While traveling has always been hugely popular, it seems like it has become far more accessible to the general public in recent years. From the construction of new modes of transportation to the lowered costs in flights, more and more people have begun to venture out to all different parts of the globe. From historical sites that should be on everyone's bucket list, to on-location sites that were made popular by depictions on both the small and big screen, there are a number of different tourist destinations that have become bombarded with an astounding number of travelers.

Oftentimes, being considered a sought-after travel destination is seen as a positive since it can help boost the local economy. Yet, the influx in tourism to some of these sought-after travel spots has actually caused some negative effects that have changed the entire experience for new visitors. From damage to the actual environment, to upset amongst the local residents, there have even been a number of travel sites that have had to implement restrictions on the number of people that can visit the area. From limiting daily tourists to complete closures, it's amazing how many places have seriously gone downhill due to mass-tourism. Check out our list of the 25 places that went downhill after tourists took over and see if there is still an opportunity to check something off the bucket list.

25 Scotland’s Harry Potter Bridge

Fans of the Harry Potter film series have flocked to see a portion of a route that was used by the Hogwarts Express. The Scottish locals have had their fair share of tourism due to the Jacobite clansmen Glenfinnan Monument but the influx of tourists to the Glenfinnan Viaduct has caused a huge impact to the traffic in the area.

The available parking has no longer been able to withstand the influx of tourists to the area and visitors have resorted to parking on single-track roads.

In June 2018, The Scotsman quoted Glenfinnan Community Council chairman Duncan Gibson stating, “It’s getting to the point that it’s getting dangerous, and emergency vehicles can not get up the road.”

24 Taj Mahal

As part of the New7Wonders of the World, the Taj Mahal is considered one of the locations that is on everyone's bucket list. With an incredible backstory of being built for the beloved wife of the Mughal emperor in the 17th century, visitors flock to see this vast complex. The main tourist attraction entails seeing the marble graves that feature semi-precious stones and really show off just how spectacular the site is, despite the actual graves being in a separated lower chamber.

Unfortunately, there is quite some damage caused to the structure, from all the foot traffic.

Global Village Space released a report on how future tourists will have to be limited and stated, "Experts say the vast crowds increase wear and tear on the white marble tomb, which already must undergo regular cleaning to stop it turning yellow from polluted air, and could put pressure on its foundations."

22 Denali National Park And Preserve

While there are some tourists that seek out serene beaches and palm trees, there are others that seek out more of a picturesque locale that really entrenches the individual into nature. The Denali National Park and Preserve is a landmark in Alaska that boasts six million acres of wilderness with an iconic road that bisects it. In an effort to minimize the effects of human interaction with the wildlife and natural elements, travelers must adhere to the strict practices set in place. Visitors are no longer able to drive their own cars and must submit themselves to win the "Road Lottery" which allows for a single day permit to drive the iconic Denali Park Road.

21 Half Dome

Yosemite National Park is a huge attraction in the United States and it's often a must-see locale for those wanting to really immerse themselves in nature. Yet, there has been quite a lot of focus centered on the effects the human interaction with the park has had with the natural elements and that has directly affected the ability hikers have to partake in the Half Dome feature.

The influx in tourism and the concern regarding the wildlife and habitat has forced the Half Dome to limit the number of tourists that can hike it.

In 2013, USA Today reported that the National Park Service authorities would limit hikers to just 400 a day via an approved permit.

20 Machu Picchu

Machu Picchu is the most well-known icon of the Inca civilization and has become a huge travel destination for tourists around the year.

Every year, Machu Picchu receives a huge number of visitors that bring a great boost to the economy in Peru.

Yet, there have been some worries regarding the increase of travelers to Machu Picchu with each passing year. The Traveller quoted Sandra Doig, from the Commission for the Promotion of Exports and Tourism of Peru, which stated, "Machu Picchu is a great attraction, but we are worried about its sustainability... It is being affected by too many people at the citadel at the same time." New regulations regarding when and where tourists are allowed at the historic site have been implemented to counteract some of the negative effects the tourists have had on the area.

19 Cinque Terre

Cinque Terre is a hugely popular tourist destination on the Italian Riviera that features pastel-colored houses and quaint fishing harbors in the Liguria region. While it had long been thought of as a must-see stop for travelers in Italy, a drastic increase in tourists put an enormous strain on the villages. In 2015, The Italian Tribune reported, "The opening of a new cruise ship terminal at the nearby port of La Spezia has increased the number of day trippers by around 30 percent. The tourists swarm through the villages, crowding narrow alleyways and overwhelming local services."

18 Santorini

Santorini in Greece has long been considered a dream vacation spot for people all over the world, and the whitewashed walls and blue-domed roofs have been depicted on both the small and big screen.

In 2013, the Kardashian/Jenner clan once visited Santorini for Keeping Up with the Kardashians and there have also been a number of well-known chefs to visit the region for its signature cuisine.

Yet, increased tourism has also brought on some negativities to the region. In 2017, The Guardian reported, "Like the staggering debt load at the root of Greece's long-running drama with financial issues, the tourism boom has amplified socioeconomic tensions and placed an intolerable burden on the island’s infrastructure. Behind the scenes, local people are becoming agitated."

17 Venice

The Italian city of Venice has been a must-see travel destination for many years but it seems to have fallen into the same pitfalls as the booming cruise industry. The influx of tourists, due to cruise ships unloading visitors into the city has caused Italian government officials to rethink how they handle the overcrowded streets and Grand Canal. In April 2018, CNN reported,

"Venice has come up with a new plan to cope with the huge numbers of visitors that continue to strain its infrastructure: segregating locals and tourists."

Not only will visitors be restricted from certain areas but some motorists will be turned away.

16 Dubrovnik

When HBO first premiered Game of Thrones in 2011, it was immediately apparent that there was something utterly special about this new series. Based off of the fictional world of the Seven Kingdoms from A Song of Ice and Fire by George R. R. Martin, fans of the book series were thrilled to learn that some real-world locations were featured in the show.

The city of Dubrovnik in Croatia can be recognized as the setting of King's Landing in Game of Thrones and has been featured throughout the show.

In 2017, Time reported, "A tourist boom has hit Dubrovnik, Croatia -- so much so that the city is now trying to combat overcrowding."

15 Galápagos Islands

The Galapagos Islands has been a hugely iconic location ever since Charles Darwin used his observations of the wildlife in his book, The Origin of Species. His findings were hugely influential in the scientific view of the biological origins of life and have ultimately earned a place for the Galapagos Islands on a number of bucket lists for travelers from around the world. In 2012, The Guardian reported on how the once untouched environment of the Galapagos Islands has completely changed due to mass tourism to the area. From contaminated groundwater to oil leakage from "hundreds of boats [waiting] to receive the next intake of tourists," there are even unique species that are in a "high risk of extinction in the wild."

14 The Koh Khai Islands

Thailand has been increasingly receiving more and more visitors each year due to its crystal clear waters and amazing beaches. Numerous celebrities have long thought of Thailand as a favorite place to vacation and have even been featured as a vacation spot when the Kardashian/Jenner clan visited on Keeping Up with the Kardashians.

Yet, the popularity of the Koh Khai Islands in Thailand has also caused some negative effects on the environment.

In 2016, Global News reported, "closures are due to a massive increase in tourism, causing irreversible damage to the endangered coral reef."

13 Jeju Island

Off the coast of the Korean Peninsula, there are islands that have become hugely popular for tourists. Jeju Island is the largest and has become increasingly more popular in recent years. Although there are only around 660,000 residents of the island, there are 15 million tourists that vacation on Jeju Island each year. The Korea Times reported on the government's new plan of building a new airport in southern Jeju, in order to accommodate the already strained airports, and it's said to increase the tourists to 45 million by 2035. The influx in tourism has caused the underground water to be "in danger of being exhausted," and the traffic and trash has caused local residents to protest the tourists.

12 Reykjavik, Iceland

Iceland has been a hugely popular tourist destination over the years, especially for those looking for a vacation filled with majestic scenes and natural elements that can really cause jaws to drop. A number of areas in Iceland have actually been used as locations depicted in HBO's series, Game of Thrones, and there have also been quite a few travel shows to stop off in Iceland to show off its unique features for tourists.

Yet, the popularity of Iceland has created seven times more tourists than locals and it's created major tension.

In 2017, Iceland magazine reported, "Defecating in the open air, stealing road signs and even stealing a young lamb to be cooked on a barbecue, are just some of the actions of tourists that have angered locals in Iceland."

11 Barcelona, Spain

Barcelona is a city with a rich history and a population of around 1.6 million and travelers from around the world make their way to Barcelona in record numbers. In a single year, Barcelona can receive over 15 million tourists, and it's caused a big strain on the locals and their living conditions. Home-sharing networks have caused some landlords to drive up the cost of rent and it's threatening to push locals out. Fox News reported on the number of protests from the locals and stated, "Barcelonians are reportedly at their wit’s end with the wild antics of rowdy tourists, who are said to be urinating in public, littering playgrounds with substance paraphernalia and passing out in the streets of the Catalonian capital."

10 Caño Cristales

While Colombia was once seen as far too dangerous for tourism, new proclamations within the government has increased the tourism rate over the years. The New York Times reported that what was once a small trickle of tourists has turned into a flood and there has been worries over the affect it has had on the environment.

The Caño Cristales river is known as "the river of five colors" or "the melted rainbow" because of the specialty foliage and algae that creates a rainbow of colors in the river. In February 2018,  The New York Times quoted the author of a four-year regional study, Carlos Lasso, who stated,

"It's a unique ecosystem, and it's very fragile."

There is talk of further limiting the tourists, as well as tension regarding the oil companies and the government.

9 Maya Bay, Thailand

When Leonardo DiCaprio starred as the lead in the 2000 film, The Beach, it seemed like it instantly showcased an already favored travel destination. Thailand's Maya Bay in the Andaman Sea was featured in the film and tourists constantly travel there to take photos in the same locations as scenes in the film. Yet, the photos don't turn out like the pristine scenes in The Beach since it's completely overcrowded with other picture-taking tourists, and loads of speedboats in and out of the bay. In May 2018, CNN reported Thailand's Department of national Parks, Wildlife and Plant Conservation's decision to close Maya Bay for a four-month rejuvenation program. The evaluation of the negative effects of such an influx in tourists has caused many to wonder what the future will be for May Bay.

8 Boracay, Philippines

Tourists around the world are often seeking out beach destinations, but there is definitely some that seem far more appealing than others. Boracay has brought an increasing number of travelers each year because of its signature powdery beaches with white sand and clear waters.

Local businesses have sought to capitalize on the booming tourist destination that filled the area with a festive nightlife.

Yet, the boom in tourism also brought on months of closure because of the fears regarding the negative effects brought on by mass-tourism. The Traveller reported on a government study that stated, "Neglected infrastructure and growth of resorts threatened to turn Boracay into a "dead island" in less than a decade."

7 Great Wall Of China

With the incredible history behind the Great Wall of China, it's not surprising that people would want to flock to see it and get their chance to walk along this historic path. Yet, people are often quite surprised by what they see (or don't see) once they do reach the Great Wall of China due to the incredible overcrowding of tourists. The Beijing Times reported that not only has 30 percent of the fortification disintegrated due to erosion and damage caused by humans. On top of that, there are also sections of the wall that have been sprayed with graffiti and it definitely doesn't fit in with the experience that tourists expect to have when visiting.

6 Angkor Wat

Cambodia is home to one of the largest religious monuments in the world and millions of tourists flock to Angkor Wat to see the incredible temple complex that was originally created as a Hindu temple. While the historical and religious aspects of Angkor Wat is definitely a draw, many people travel there to witness the spectacular sunrises that can be seen from the steps within the complex. Yet, the influx in tourists has also caused some to worry about the structural and environmental factors that have been changed due to mass-tourism. A member of the Cambodian tourist board was quoted by CNN in 2015, and stated, "I think that many sites need to determine cultural and environmental carrying capacities, and then limit visitation numbers to sustainable numbers."
