Volcanoes are both awe-inspiring and ferocious. They’re a testament to the power and wonder of Mother Nature, beautiful and fearsome at the same time. There’s no denying volcanoes are some of the most dangerous places on the planet. At the same time, they can also be some of the most beautiful.

If you’ve ever pondered a photo of red-hot magma erupting from a volcanic cone or watched video of lava creeping its way down a mountainside and felt the need to get closer, this list is for you. There are many places around the world where you can experience the thrill of hiking up a real, live volcano. From sleeping giants to bubbling calderas, from tiny shield volcanoes to soaring, ice-capped peaks, you can conquer some of the world’s most dangerous, active, and beautiful volcanoes.

A word of caution for the wise, since we want you to be safe wherever your adventures take you. Volcanoes are often unpredictable, so always exercise caution. Check in with authorities before attempting any of these hikes, and make sure the volcano is safe. If you plan carefully, you’ll have amazing adventures to tell your friends after successfully completing some of these challenging volcanic hikes.

20 Erta Ale, Ethiopia—The Hottest Place On Earth!

Welcome to the Afar region of Ethiopia, the home of Erta Ale. This area isn’t exactly the safest in the world, due largely to ethnic clashes, which is why all treks to Erta Ale have to be accompanied by an armed escort. The landscape itself is particularly harsh, so it’s a good idea to have an escort anyway. This is the hottest place on the planet.

From the colorful and strange Danakil Depression, you’ll take a rough, multi-hour journey by 4x4 to base camp. From the camp, it takes about 3 hours to hike to the volcano itself. Your hike will almost certainly take place after sunset, when the heat of the day has faded. Exerting yourself in the hot sun in the hottest place on Earth isn’t exactly the best idea. When you reach the top, you’ll spend a night at a rustic camp, sleeping on thin mats underneath the stars. You probably won’t miss the blankets.

Erta Ale is Ethiopia’s most active volcano, and it erupted as recently as January 2017. Its most prominent feature is its lava lake, one of a mere handful in the world. The lake has been there since 1906, and you can view it today, bubbling and spitting, after making the trek to the summit.

19 Kilauea, Hawaii—The World’s Most Active Volcano

The Hawaiian Islands were formed by volcanic activity on the deep seafloor. Over millennia, underwater volcanoes built up the land mass until they rose above the ocean. As the tectonic plates beneath the Earth’s crust move, the “hot spot” moves as well, resulting in the chain of islands we see today.

The Big Island of Hawaii is currently over this hot spot, so it shouldn’t be surprising to know this island is home to active volcanoes. In fact,

There are 5 volcanoes on the Big Island, and 3 of them are currently considered active. Hualalai is the least active. Kilauea is the most active. The latter is actually the world’s most active volcano. Kilauea has been erupting almost without stop since 1983. It’s made headlines since early May 2018, when a new round of eruptions endangered homes.

Currently, the area around Kilauea is very volatile and quite dangerous. At other times, however, it’s possible for people to hike around the Hawaii Volcanoes National Park. The 11-mile Crater Rim Trail circles the caldera of this shield volcano, while the Kilauea Iki Trail will take you to the Kilauea Iki Crater’s lava lake. The 18.8-mile Chain of Craters Road ends where the lava flows into the Pacific Ocean.

Other popular trails include the Halema’uma’u Trail, a 1.8-mile hike to the crater itself, and the Napau Trail, which takes you across 14 miles of backcountry as you follow the flow of magma underground to exposed lava fields.

18 Visit A Sacred Crater Lake At Mount Rinjani, Indonesia

Mount Rinjani soars above the clouds at 12,200 feet, making it the second highest peak in Indonesia. At this height, you can guess that getting to the summit is quite difficult, and relatively few make it all the way to the tip-top. Most people prefer a trip to the rim of the volcano’s crater. Even getting to this lower altitude is no walk in the park—it’s a 2-day endeavor!

The hike to the crater has historically been a spiritual journey for the locals, who consider the crater lake sacred. Segara Anak is located around 6,600 feet above sea level, or just about halfway up the mountain. The lake is estimated to be about 660 feet deep. The 4-mile-by-5-mile caldera is also home to Aik Kalak, a hot spring, and Gunung Baru, an active “baby” volcano.

There are two access points to climb Mount Rinjani. You’ll sign up for an organized trek and depart from Senaru or Sembalun Lawang. From there, you’ll head into Gunung Rinjani National Park and hike to Pelawangan II, the northeastern part of the crater. After spending part of the night here, you’ll rise around 2 am and continue on to the summit. You’ll arrive before sunrise. Take in the spectacular view from above a carpet of clouds. By mid-morning, it will all be covered over by clouds, but you’ll have your memories as you begin your descent.

17 Hike Europe’s Largest Volcano: Mount Etna, Italy

Italy’s Mount Etna is something of a legend. Located just outside of the Sicilian community of Catania, this 11,000-foot giant is Europe’s largest volcano. It’s also one been one of the world’s most active volcanoes, erupting more frequently throughout history than many others. Currently, only Hawaii’s Kilauea is considered more active.

Mount Etna might hold the world record for the longest period of action for any known volcano. The first recorded eruption hit the books in 425 BC.

To hike Etna, you’ll depart from Catania’s railway station, either by bus or by car. From there, you’ll take a cable car to the stations around the mountain. You can opt for either the “long trek,” which will take you to the very summit, or the “short trek,” which will take you to one of the lower craters on the volcano. The long trek has one daily departure in the early morning. For the short trek, you’ll take a cable car halfway up the mountain, then travel by 4x4 before hiking to the crater.

To get to the very summit, you’ll need to arrange for a certified mountain guide to go with you. In the summertime, you’ll be able to visit some of the steaming craters in the area, or discover one of the many trails. You may even see flowing lava if this “friendly giant” is particularly active. Keep in mind eruptions may block off the highest craters. Always check the volcano’s status in advance and adjust your plans accordingly.

16 Enjoy An Epic Sunrise Over Mount Bromo, Indonesia

Mount Bromo may not be the highest volcano in Indonesia or even the highest peak on the Tengger massif, but it is one of the most famous. The massif area is one of the most visited tourist attractions on East Java, and congestion is common on many of the trails to and around Mount Bromo.

Mount Bromo is something of a stereotypical volcano. It’s constantly smoldering, and even though its last eruption was in 2015, white smoke billows out of it every day. You’ll need a mask if you plan to approach the summit.

Despite its height, Mount Bromo is very popular because it provides a relatively easy hike. It will take you about 3 hours of easy walking through the Tengger Sand Sea, followed by some steep stairs to the crater itself.

You can book a tour or take on Mount Bromo as an independent adventure. To get there, book a car or take public transport to Cemoro Lawang, a village on the edge of Bromo Tengger Semeru National Park. From there, you can hike Bromo, or you can explore one of the other mountains in the area. A popular climb is Mount Pananjakan, which offers the highest viewpoint. If you get up early enough, a sunrise over Bromo will be your reward. If early morning hiking isn’t your style, you can book a jeep tour or a horseback ride.

15 Hike To The World’s Largest Caldera On Mount Aso, Japan

Japan sits on the Pacific Ring of Fire, along several fault lines. As a result, the island nation often weathers natural disasters such as earthquakes and tsunamis. It’s also home to several volcanoes. Mount Fuji is the most famous, but is largely considered to be dormant.

Japan’s most active volcano is currently Mount Aso, located at the center of Kyushu. Mount Aso is impressive for many reasons. It actually boasts the world’s largest caldera, measuring 16 miles in diameter and 80 miles in circumference. There’s even a hill named Komezuka inside it. Mount Aso features 5 volcanic peaks, with Mount Nakadake being the most active. A steaming, cyan lake is another feature inside the crater. All 5 peaks have well-developed trails.

Reaching Mount Aso is relatively easy. You can take the train to Asosan Nishi Station, about an hour from Kumamoto. From there, it’s about 30 minutes of relatively easy hiking. If you prefer to drive, a toll road will take you right to the summit, with a large parking lot on the way. Two cable car lines also operate up and down the mountain.

While you’re here, you can learn more about the volcano in the Aso Volcano Museum or explore the rest of Aso-Kuju National Park. The area surrounding the volcano is well-developed. You’ll find hot spring resorts in the towns of Aso, Tarutama, and Jigoku. If the caldera happens to be closed off due to emissions, you can sit back and relax instead.

14 Whakaari/White Island, New Zealand—Only 10% Of It Is Above Water

You’ll find Whakaari, or White Island, in New Zealand’s Bay of Plenty. The island sits about 30 miles from the east coast of the North Island, so you’ll need to travel to it by helicopter or by taking a 90-minute boat ride.

Whakaari is unique in that you’ll be dropped off into the crater itself, which means you can explore this volcanic landscape without needing to hike steep trails. This is because Whakaari is a marine volcano, the only active one in New Zealand.

It’s been built up by continuous activity over the last 150,000 years, and it’s currently the most active volcano in New Zealand. It’s also the largest. Only about 10% of the volcano is visible above the ocean surface. The rest of it, measuring a total of 5,249 feet, is underwater.

Upon arrival, you’ll be greeted by what appears to be a moonscape. You’ll be able to visit the crater, crater lakes, and the remains of a sulfur factory. Whakaari constantly emits sulphuric acid, which is responsible for the colorful reds, yellows, greens, and blues that dot the landscape. You’ll need to wear masks and hard hats for safety.

Whakaari erupted in 2013 and 2016, and it’s considered “restless” by scientists. Its usual activity includes expelling hot steam and gas, but another eruption isn’t out of the question. As with all volcanoes, check in advance and exercise caution.

13 Even Frozen Wastelands Have Volcanoes: Mount Erebus, Antarctica

While most people likely imagine tropical or subtropical islands when they think of volcanoes, a volcano can occur anywhere around the world. They can even erupt through layers of ice and snow. Such is the case in Antarctica, where several volcanoes have broken through. Volcanic islands, such as Ross Island and Deception Island, are common.

Ross Island is characterized by 4 volcanic peaks, Mount Terror, Mount Bird, Mount Terra Nova, and Mount Erebus. Standing tall at 12,448 feet, Mount Erebus is the second highest of Antarctica’s several volcanoes, dwarfed only by Mount Sidley. Mount Terror, also on Ross Island, is a dormant volcano. Mount Sidley is also dormant, leaving Mount Erebus as the southernmost active volcano on earth. Mount Erebus is also the sixth highest ultra-mountain on an island.

Mount Erebus has been continuously active since 1972. It was first summited in 1908, with its first winter and solo ascent happening in 1985. In 1991, a solo climber summited the volcano in 17 hours on snowmobile and on foot. It’s the current site of the New Mexico Institute of Mining and Technology’s observatory. Obviously, hiking up Mount Erebus is an extreme challenge, both to reach it and then to scale its summit.

12 Head To Mayon, Philippines, For A Multi-Day Hiking Adventure

Mayon is renowned for its “perfect cone,” as well as the white smoke almost constantly billowing from its narrow tip. If you closed your eyes and imagined a volcano, Mayon is likely what you’d picture.

Mayon, or Mount Mayon, has the distinction of being the most active volcano in the Philippines. It’s erupted about 50 times since the 1600s, and its most recent eruption was in January 2018. It hardly needs to be said that you’ll need to approach Mayon with caution and due respect, just the same as any volcano. Volcanoes are unpredictable forces of nature, so exercising caution is always wise.

Mayon deserves your respect for another reason. The hike up to the summit, you’ll need at least 2 days, if not 3. Trail Adventours ranks the hike as a 7 on a 10-point difficulty scale. Mayon is known to spew rocks and ash, adding to the difficulty and danger of the hike. If you’re in the mood for something more sedate, you can hike around its base, through the trails of Mayon Volcano Natural Park.

If you’re in the mood for more adventure, you can push on to the top for scenic views of Legazpi city and the Pacific Ocean far below. Either the Buyuhan Trail from Buyuhan or the Buan Trail from Tabaco will take you to the top.

11 Eyjafjallajökull, Iceland—Hard To Pronounce, Harder To Hike

Iceland has many things to recommend it to tourists. You can check out the capital city of Reykjavik. Most tourists head to the popular Blue Lagoon. Others can get a taste of Viking history at Thingvellir National Park. Glaciers, black sand beaches, and wilderness hiking are all part of an Icelandic tour.

You can add volcanoes to the list of things to hike in Iceland. Eyafjallajökull is an active volcano and a tourist hot spot, despite its caldera being covered over by an ice cap. The Icelandic name of this 5,417-foot high volcano means “island mountain glacier.”

Iceland has around 130 volcanoes total, with the Angry Sisters Katla and Hekla being 2 of the most active. Eyafjallajökull is the most active, erupting quite frequently. It gained notoriety in May 2010 when it sent plumes of ash and smoke into the air and halted air traffic across Europe for a week.

You’ll need to book a guide in order to make the dangerous, 4-mile trek to the top of Eyafjallajökull. Without a guide, you won’t be allowed to hike on the mountain. These days, you may have some trouble finding a guide to take you. Many large new crevasses have opened up recently, making Eyafjallajökull quite dangerous, even for jeep tours. Instead, take a 15-mile hike across Fimmvor∂uhals Trail for scenic waterfalls, rivers, and lava fields.

10  Get Up Close And Personal With Lava At Mount Yasur, Vanuatu

If you want to see some lava, book travel to Mount Yasur. Located near Sulphur Bay on Tanna Island, Vanuatu, this coastal volcano almost never disappoints. Mount Yasur is relatively short, rising just 1,184 feet above sea level. As a result, it makes for relatively easy hiking up to the summit of the unvegetated cone.

The summit is nearly circular, crowned by a 400-meter wide crater. This stratovolcano emerged because of the Indo-Australian plate moving underneath the Pacific Plate, much like the other volcanoes in the area. Mount Tukosmera, to the northwest of Yasur, is older and taller. It was active during the Pleistocene era.

Mount Yasur, although much younger, has been erupting nearly continuously for more than 800 years. Despite this, it’s usually safe to approach with caution. Mount Yasur is well-known for its craters full of lava, and it regularly gives lightshows as lava sprays up from the craters.

Always check in with local authorities and tours before you head out for the day, and exercise your better judgment when approaching a volcano. Although beautiful, they are also dangerous. Sometimes, the awe-inspiring forces of nature are best viewed from a safe location further away.

9 Mount Vesuvius, Italy—Climb The Volcano And Visit Pompeii

Mount Vesuvius is possibly the best-known of Italy’s 3 active volcanoes, despite not being the largest (Etna) or the most spectacular (Stromboli’s lightshow is hard to top). Vesuvius earns its reputation on historical fact. An eruption in 79 AD buried the Roman city of Pompeii. As a result, Pompeii is the best-preserved Roman town we have, and it’s an incredibly popular tourist attraction.

Vesuvius is relatively inactive, having erupted only about 36 times in recorded history. Nearby Naples sits in its shadow and may one day face the same fate as Pompeii. For the time being, however, you can join other adventurers and volcano enthusiasts and hike mainland Europe’s only active volcano.

Vesuvius National Park offers 9 different trails, all of them with different levels of difficulty. If you’re a beginner, you’ll find some friendly trails to accommodate you, while those with more experience will find a challenge among the more “advanced” trails. Trail 5, Gran Cono (the Big Cone), is the most popular trail. Trail 4 sees less traffic, but it’s considered more manageable and offers some of the best views.

The hike to the crater itself is relatively steep, but the views are worth every step. Vesuvius was originally much higher, but has since collapsed, leaving a large cone encircled by the rim of its summit caldera. The path will take to the very edge, where you’ll be able to see steam rising from the crater. A trip to the historic museum rounds out your trip.

8 Never Mind Hiking: You Can Mountain Bike Down Cotopaxi, Ecuador

Many things set Cotopaxi apart from other volcanoes. For one, it’s the second highest mountain in Ecuador. It’s also the third most active volcano in the entire world, just behind Kilauea and Mount Etna. Since 1738, it has erupted more than 50 times. Standing proud at 19,300 feet, it’s also one of the highest active volcanoes in the world.

Located just outside Quito, Ecuador’s capital city, Cotopaxi is considered the “main attraction” of the Avenue of the Volcanoes, which cuts through the Andes Mountains. Cotopaxi’s activity has transformed the surrounding landscape. The volcano is surrounded by lahars and volcanic mudflows that have created numerous valleys.

You’ll likely want a guide to accompany you on a trip to the icy summit. It’s a 2-day climb even for experienced hikers and mountaineers. Multi-day tours provide you with warm-ups to prepare for summiting. Cotopaxi also offers another option for those seeking unique adventures: You can actually mountain bike back down. Of course, that means you’ll need to haul your bike with you to the top, but many feel the exhilaration is worth it.

If climbing to an icy peak or whizzing back down an active volcano on a mountain bike aren’t your speed, you can opt to explore Cotopaxi National Park more thoroughly. The area offers many different trails to challenge hikers of all skill levels.

7 Pacaya, Guatemala, Will Remind You Of Summer Camp

Guatemala has several volcanoes, most of them located close to the city of Antigua. Pacaya is perhaps one of the more famous volcanoes in the area, at a distance of about 2 hours driving from the city. Pacaya isn’t as ancient as some of the volcanoes on this list, first erupting about 23,000 years ago. It’s erupted about 23 times since the 1500s, but it was dormant for nearly 100 years between 1865 and 1965. In 1965, the volcano “woke up” again, and has been erupting ever since.

Pacaya became popular with adventure-seekers because you used to be allowed to walk right up to the lava, sometimes until your shoes melted. Access has since been restricted, which is probably for the best, as it’s much safer to stand back a little. These days, you’ll need a guide. You can either join a tour or hire one from the visitor’s center.

Pacaya is a moderately steep hike. It’s also a relatively short one, about 2 miles total. You’ll pass hot steam and lava formations on the way, which makes it more strenuous. If you prefer, you can opt to ride a horse. As you reach the fumaroles, your guide will likely hand out some marshmallows to toast over the heat rising from the ground. If you think ahead, bring some graham crackers and chocolate, and make s’mores!

6 Villarrica, Chile—1 Of 5 Volcanoes With A Literal Lava Lake

This South American volcano is just 1 of 5 volcanoes in the world with a literal lava lake inside its crater. Despite the heat at the top, you’ll find yourself weathering a snowy, icy hike to reach the summit of Villarrica. Located in the rugged Patagonia region, Villarrica is one of Chile’s most active volcanoes and the westernmost of 3 large volcanoes running along the Gastre Fault. All 3, Quetrupillan, Lanin, and Villarrica, are located within the boundaries of Villarrica National Park.

Villarrica is a popular hike for visitors, although you’ll need a guide unless you’re a mountaineer yourself. Several guided ascents reach the summit each summer, leaving from Pucon. Mountain biking tours will also take you toward the top. You can hop on a chairlift for $30 and save yourself 1.5 hours of hiking. And once you’ve reached the top, you might find taking a sled ride down the slopes is a more enjoyable way to make the return trip.

Villarrica is located near a town and a lake of the same name. It’s also known as Rucapillan, or “the House of the Pillan.” Part of the Torres del Paine region, Villarrica isn’t the only mountain you can climb, although it has been called the hardest hike. Villarrica’s eruptions make it very dangerous, partly because lava mixing with melting snow makes them more violent.

5 Piton De La Fournaise, Reunion Island—Prepare For An Incredible Lightshow

Piton de la Fournaise is located on Reunion, a small, French-held island in the Indian Ocean. Its name, which is French, means “Peak of the Furnace.” A shield volcano like Hawaii’s Kilauea, it also ranks as one of the most active volcanoes in the world.

Known simply as “le Volcan” (or the Volcano) to locals, Piton de la Fournaise is a major tourist attraction. It’s located on the eastern side of the island, inside Reunion National Park. It’s also been designated a UNESCO World Heritage site. There’s no public transport, so you’ll need to get there by foot or by car. A good forestry road connects Highway of Plains to Pas de Bellecombe. From Pas de Bellecombe, well-signed paths will lead you through subtropical scenery to any of the many volcanic craters in the area. Various roads and paths link both active and dormant craters.

Keep in mind that Piton de la Fournaise is very active, frequently giving lightshows and producing lava flows. Eruptions have been recorded from August 2006 to January 2007, February 2007 to September 2008, December 2010, and again in August 2015. The most recent eruption began in July 2017 and is currently ongoing. Access to the most active calderas is often intermittent because of this high level of activity.

4 Visit The Site Of The Eruption Felt Around The World: Krakatoa, Indonesia

The name Krakatoa is practically synonymous with volcanoes. Krakatoa is a real place, located in the Sunda Strait between the Indonesian islands of Java and Sumatra. The name actually refers to the surrounding island group, which are the remnants of what was originally a single island with 3 volcanoes.

Krakatoa isn’t the largest volcano or the most active, but it certainly is one of the most explosive. It erupted in 1883, destroying two-thirds of the island. The sound could be heard 3,000 miles from the origin point, making it the loudest sound in modern history. The shockwaves were recorded around the world. Krakatoa sent so much smoke and ash into the atmosphere, the Earth actually got a couple of degrees colder.

With such a violent eruption, it’s little wonder “Krakatoa” has become shorthand for explosive volcanic activity.

Krakatoa has been quieter for the last century or so, but the area is still the site of eruptive activity, and it has been for a while. The emergence of a new island in 1927 demonstrates this. Anak Krakatau, or “child of Krakatoa,” is also volcanic and popular for hiking. Anak Krakatau is growing at a rate of about 16 feet per year, and was recorded at 400 meters high in 2017.

3 Mount St. Helens, USA, Is A Hikers’ Paradise

Although we like to think of volcanoes as part of some far-off lands, the truth is you don’t need to travel very far to hike one. In fact, you can find several on the mainland United States, including the infamous Mount St. Helens in Washington state. This 8,300-foot volcano last erupted in the early 1980s. The eruption was violent, sudden, and explosive. It triggered the largest landslide in human history, released 24 megatons of thermal energy, blew the top off the mountain, and laid waste to an area of more than 200 square miles.

Given Mount St. Helens’ dramatic history, it makes sense the number of visitors allowed on the mountain is limited at any time. If you plan to summit, you’ll need to obtain a permit well in advance. Gaining the summit isn’t easy, but it offers spectacular views. The 28-mile Loowit loop will take you through the 1980s blast zone, up to Monitor Ridge. From there, you’ll tackle a rigorous ascent through ash, rocks, and boulder fields. At last, you’ll reach the rim of the colossal crater.

The area around Mount St. Helens, just under 100 miles south of Seattle, offers well over 200 miles of trails, so heading up to the tip-top isn’t your only option here. The Meta Lake loop is stroller- and wheelchair-friendly. You’ll see waterfalls, lakes, canyons, caves, and even an emerging glacier on a hike near Mount St. Helens.

2 Sakurajima, Japan—A Constantly Smoldering Threat

Sakurajima was once an island in Japan’s Kyushu region. A 1914 eruption changed that, as lava flows connected the island to the Osumi Peninsula. Sakurajima, or “Cherry Blossom Island,” is an active volcano, constantly smoldering. Mini-eruptions occur almost daily, and the volcano is known for emitting large amounts of volcanic ash.

Sakurajima is considered quite volatile, so although you can hike it, you’ll need to check with authorities to make sure it’s safe to hike to the peak on any given day. It most recently started erupting on May 2, 2017, and some scientists think it’s due for a major eruption within the next 30 years.

If Sakurajima is deemed too dangerous during your visit, you can explore the area in other ways. There are many trails around the base of the mountain. These scenic hikes allow you to get close to it and take in some of the volcanic landscape, such as Sakurajima’s white sand highlands, which were created by eruptions. Yunohira Observation Point is about 2 kilometers away from the craters. It’s occasionally the closest you can get to the action. Afterwards, it’s just a short walk back to the ferry terminal, which will take you back to Kagoshima.

1 Stromboli, Italy—There’s A Reason It’s Called The Lighthouse of the Mediterranean!

Just off the north coast of Sicily, in the Tyrrhenian Sea, there’s a small island called Stromboli. This island, dominated by a massive mountain, is home to 1 of Italy’s 3 active volcanoes. It’s also 1 of the 8 islands making up the Aeolian volcanic arc. The island’s name comes from the Greek “strongule,” referring to its rounded shape.

Stromboli is world-renowned for its spectacular pyrotechnics. It’s been active since 1932, with minor eruptions happening approximately every half-hour. Stomboli’s lightshow is often visible around the island and out at sea, earning it the nickname “the lighthouse of the Mediterranean.”

Stromboli’s activity makes it fairly dangerous, so you’ll need to be in a guided group if you plan to climb to the summit. You can climb to Sciara del Fuoco, a point around 400 meters up, without a guide. To get here, you’ll follow an attractive trail starting in Piscita. The trail is steep, and it can be cold and windy, so take a jacket with you.

If you plan to take a guided tour, you’ll likely leave just before sunset. The tours are timed to reach the summit at sunset, then allow about 45 minutes to observe nature’s most spectacular fireworks show. You may even see lava roll down the mountain, burning bright in the darkness of the night. Bring a flashlight, and factor about 6 hours for the trip to the top.
