The Great Blue Hole: 9 Pics That Will Make Us Shudder (16 That Make Us Want To Visit)

The Great Blue Hole is the world’s largest natural formation of its kind, and it is part of the larger Barrier Reef Reserve System in Belize. It is a World Heritage Site of the United Nations Educational, Scientific, and Cultural Organization (UNESCO), and is ranked as a top scuba diving site in the world. Its fame has stemmed from its beautiful waters, stunning size and grandeur, and its fantastic variety of marine life.

The Great Blue Hole has been described by NASA as “surrounded by darker, deeper ocean waters, with coral atolls that often glow in vibrant hues of turquoise, teal, peacock blue, or aquamarine. Belize’s Lighthouse Reef Atoll fits this description, with its shallow waters covering light-colored coral: the combination of water and pale corals creates varying shades of blue-green. Within this small sea of light colors, however, lies a giant circle of deep blue”. Their description of the beauty cannot do it justice enough though. It is an incredible site and is renowned for a reason. It is an amazing destination to take in all that mother nature has to offer, and there are numerous adventures awaiting you to discover.

Here are 13 pictures that make us want to visit, and 12 that will make us shudder.

Hopefully you aren’t afraid of the dark! Due to the depth of the sinkhole, sunlight is unable to reach the floor of the hole which gives the area an inky blue darkness.

Recently, Glyn Collinson, a NASA scientist explored the Great Blue Hole and stated that it was the “deepest, deep blue hole imaginable; a chasm that fell away deep into the deep, dark blue’ stated Belize.com. Visibility is minimal which provides a sense of isolation, so if you want to explore the area, make sure to bring a light!

17 Makes Us shudder: A Massive Sinkhole In The Caribbean Sea

Via: National Geographic

The Great Blue Hole is an enormous submarine sinkhole in the Caribbean Sea. The hole is circular and is almost 125 meters or 410 feet deep. The Curiosity states that this is taller than the world’s tallest tree and wider than three football fields across. Thousands of years ago, the Great Blue Hole was actually a dry on-land cave system, which we know by the mineral dripping which only forms in on-land cave ceilings.

Eventually, sea levels rose and caused this system to collapse and the sea filled in the hole left behind.

16 Makes Us shudder: A Giant, ominous Cave Awaits

Via: Pinterest

The Great Blue Hole is a sinkhole that was created by a ‘karst cave system’ according to the CN Traveler. According to Cahalpech, scientists believe that these structures were formed in a dry cavern above sea level during the glacial periods, but after thousands of years of erosion, the soft rock inside collapsed. However, much of these cave structures still remain visible today.

This essentially formed a massive vertical cave, which includes a limestone shelf about 40 feet below the surface and many smaller cave areas throughout.

15 Want To Visit: Surrounded By The Lighthouse Reef


The Great Blue Hole is near the centre of the Lighthouse Reef in the Caribbean Sea. This ancient sea structure might have begun developing over 70 million years ago, and might have originated on top of giant fault blocks rather than subsiding volcanoes. Most likely, limestone covered ridges settled into steps offshore which provided platforms for coral growth.

After the last Ice Age, the sea level began to rise and the coral growth expanded. This created the outer waters and shallow inside lagoon. This island of coral garners much attention annually from divers and scientists alike.

14 Makes Us shudder: Rock Formations From The Last Ice Age

Via: Pinterest

As mentioned before, the geology of the area indicates that The Great Blue Hole can be dated all the way back to the Ice Age. According to Cahalpech, water used to filter through the rocks, however millions of years ago at the end of the last Ice Age, the waters rose due to the polar ice-caps and led the caverns to be engulfed by the sea.

These forces caused this chasm to collapse onto itself and create the sinkhole that we see today. The rock formations show evidence of this, adding interest to the area.

13 Makes Us shudder: Only A Small Portion Has Been Explored

Via: National Geographic

Much of the cave area remains unexplored. Most divers can only get 40 meters or 130 feet below the surface. More than half of the cave area has not been explored in depth. IFLScience stated that a new study is being conducted in December 2018 to construct a real-life model of the sinkhole and to collect information on the water quality.

The first part of the expedition aired on the Discovery Channel, however, the research will continue. One the team is Richard Branson and Jacques Cousteau’s son, Fabien Cousteau.

12 Want To Visit: Interesting Cave System To Explore

Via: Deeper Blue

Even the most experienced divers will find the Great Blue Hole interesting. Cahalpech states that starting at the surface, divers enter a steeply walled entrance and descend to find remnants of the rock formations and cave system from the Ice Age. Much of the cave system was destroyed during the collapse of the sinkhole, however the structure remains.

Divers enjoy negotiating their way around and exploring through the rock formations, enjoying little light as they make their descent. Many are awestruck as they take in the ancient structures.

11 Want To Visit: Incredible Stalactites To See

Via: BluWaterLife

Many divers are particularly interested in the underwater stalactites and stalagmites, which were formed during the last glacial period. Some of these stalactites and stalagmites measure up to 12 meters or 40 feet in length, according to Belize.com. Cahalpech states that the first formations can be seen as you begin your descent, and divers enjoy exploring the overhangs and giant stalagmites.

If you are able to dive even further, it is possible to explore bedrock ledges and underwater dunes! Farther than that, divers find a limestone shelf, however any farther descent leads into the unknown.

10 Want To Visit: The Atolls In Belize Are A Rare Sight In The Western Hemisphere

Via: Trekking Diving Living

The Belize Atolls are an anomaly in the Caribbean. There is nothing else in the Western Hemisphere that resembles a true coral atoll according to Belize.com other than perhaps the Chinchorro Reef off of Mexico’s southern coastline in the Yucatan Peninsula.

According to geologists, they are even more rare and unusual because the origin of their formation does not seem to mimic or mirror that of the atolls that can be found in the Pacific Ocean, where rings of coral are found more frequently. Also as more coral continues to die off globally, this preserved reef becomes increasingly more special.

1 Want To Visit: Explored By Jacques Cousteau, Named By Ned Middleton

Via: Tropic Air

Belize.com states that in the mid 1970’s, Jacques Cousteau (a famous marine biologist) made an investigation into the Great Blue Hole and the atolls surrounding it. After his exploration, he stated that it was one of the top ten best dive spots on the planet. He later displayed what he found on a television series called “The Undersea World Of Jacques Cousteau” bringing attention to the area.

However, according to the Cahalpech, the actual name came from a British diver Ned Middleton, who wrote, that if Australia could have ‘The Great Barrier Reef’ then Belize could have ‘The Great Blue Hole’.
