6. Taj Mahal, Agra, India
The most famous mausoleum in the world has about 8 million visitors a year. India’s government is limiting tourists to no more than three hours there in order to prevent overcrowding. Previously it was not uncommon for some people to spend an entire day there. The Taj Mahal easily sees about 60,000 tourists a day during the peak season.
7. Zion National Park, Utah
The third most visited national park in the country attracts more than 4.5 million a year. (No. 1 is Great Smoky Mountains National Park, and No. 2 is Grand Canyon.) The National Park Services (NPS), which manages all 60 national parks in the country, has been considering an admissions cap at Zion, which is famous for its red cliffs and narrow canyons. NPS is also recommending an increase in entrance fees in the summer for Zion and several other parks, to $30 per person, $50 for motorcycles, and $70 per car. The park is also working on a possible visitor reservation system and requiring permits for popular hikes.
8. Boracay, Philippines
The famous Boracay island was closed for six months to give locals a chance to clean it up. The country’s president had described it as a “cesspool” due to its inadequate sewage system. The island reopened in October 2018, but with the number of tourists way below the daily limit. Tourism is now limited to 6,000 visitors a day at least until October 2019, down from 19,000 before the shutdown. Tourists now also have to show a government-approved hotel reservation.
9. Angkor Wat
The Cambodian government has said in its tourism management plan that restrictions on the numbers of tourists in certain parts of the site and on the time spent in the temples are necessary to preserve the complex, which dates back to the 12th century. More than 5 million people visit a year. In March 2017, it was decided that no more than 300 people will be allowed on Phnom Bakheng at one time, a very popular hill from which to watch the sunset over the ancient ruins.
The number of tourists rose by 17% — to almost 52,000 — in the year up to the 2017/2018 season. Ships with more than 500 passengers are not allowed to land while in Antarctic waters. The maximum number of visitors allowed ashore to see the scenery and wildlife is 100. A permit is required for all human activities, according to the International Association of Antarctica Tour Operators.
