12 famous landmarks that don't welcome large crowds of tourists.

Santorini, Greece:The island, famous for its blue and white color scheme, will undergo significant changes in the near future to curb the influx of cruise ship tourists, which can reach up to 10,000 people per day during the peak season from May to September. In 2017, the island will begin limiting the number of visitors to 8,000 per day.

Norway:According to The Local, Norsk Friluftsliv, Norway, is calling for limits on trekking tourists to popular spots including Preikestolen (Pulpit Rock) and Trolltunga (Troll Tongue). Norwegian rescue teams have carried out 34 emergency rescues at Pulpit Rock this year. Due to the high number of accidents and injuries, the Norwegian Tourism Association called in August for new regulations prohibiting tourists from climbing the site.

Venice (Italy):Besides rising water levels threatening infrastructure, the city of love is also witnessing a steady influx of tourists. Some scholars suggest that native Venetians will completely disappear from the city by 2030 due to increased tourism and rising rental prices that locals can no longer afford. To reduce the number of tourists, the Italia Nostra group has proposed that authorities ban boats from the harbor and that large groups of tourists book in advance.

Koh Tachai, Thailand:This island, part of Similan National Park, was closed in October 2015 after being overcrowded with tourists. Three other islands in Phuket—Koh Khai Nok, Koh Khai Nui, and Koh Khai Nai—followed suit. Tour operators had to strictly adhere to regulations regarding when and where tourists could visit and how they could travel to the islands. Beach chairs and umbrellas were also removed.

Zion National Park, Utah, USA:Zion is expected to welcome a record number of visitors this year, with 4 million. However, to avoid soil erosion and vehicle overload, park leaders are considering limiting the number of visitors through a new booking system.

Barcelona, ​​Spain:The plan of the city's administrators was to balance the interests of tourists and locals, implementing restrictive policies before things got out of control. In May 2016, the city considered applying a new tourism tax for visitors entering the city without staying overnight, and for tourists traveling by boat.

Bhutan:Located in the western Himalayas, the Buddhist kingdom of Bhutan prides itself on "quality tourism with less." All foreign visitors, except those holding Indian, Maldivian, or Bangladeshi passports, must apply for a visa and book tours through a Bhutanese travel agency. Visitors must also pre-pay a minimum of $200-250 USD per day for a tour package, depending on the month as stipulated by the Royal Government of Bhutan, via bank transfer through the Bhutan Tourism Board. This fee covers accommodation, meals, guides, transportation, healthcare, and poverty alleviation. Only 155,121 tourists visited Bhutan in 2015, of which 57,537 were international visitors, with the remainder being from India, Bangladesh, and the Maldives.

Iceland:In May 2015, the number of tourists visiting Iceland increased by 76% compared to the same period in 2014, and by 2017, Iceland will have more American tourists than its own population. Currently, the Icelandic Tourism Board and the Tourism Research Centre are investigating the overcrowding of tourist sites before implementing any remedial measures.

Machu Picchu, Peru:UNESCO is encouraging measures to strictly control the number of visitors to Machu Picchu. Foreign visitors must hire guides, use one of three entrances to the complex, and have time limits to avoid overcrowding. In 2014, approximately 1.2 million visitors visited the Inca citadel, exceeding the daily limit of 2,500 set by Peru and UNESCO. The citadel was added to UNESCO's "dangerous" list earlier this year.

Cinque Terre, Italy:The cluster of five picturesque villages along the Ligurian coast, Cinque Terre, is one of Italy's most popular tourist destinations. However, authorities have recently announced plans to limit the number of visitors due to environmental concerns. While Cinque Terre attracted 2.5 million tourists in 2015, this number will now be limited to 1.5 million.

Antarctica:In 2009, the surge in tourists led to the ratification of the Antarctic Treaty. Under this treaty, ships with more than 500 passengers were prohibited from docking, and the number of tourists on shore was limited to 100. Visitors to the pristine environment had to register through authorized travel agencies and organizers approved by the government. Time spent on shore and kayaking were also strictly controlled.

Mount Everest:The Nepalese government has taken steps to control tourism, such as increasing the fee for foreign tourists climbing mountains from $10,000 to $11,000, and establishing a liaison office at the base camp to check the experience, health, and climbing ability of tourists. In September 2015, Nepal banned novice climbers and is considering age limits. Additionally, group sizes have been reduced to avoid overcrowding.
