Venice, Italy

Bali, Indonesia

Once an idyllic paradise, Bali now suffers from traffic congestion, environmental degradation, and overcrowded beaches. The island’s resources are strained under the weight of mass tourism, but there are efforts underway to promote sustainability like putting a moratorium on new hotels.

Machu Picchu, Peru

Overtourism has led to erosion and damage to this ancient Incan citadel. A quota system and mandatory guides are helping preserve this popular South American destination.

Tulum, Mexico

Once a tranquil paradise known for its pristine beaches, ancient Mayan ruins, and eco-chic vibe, Tulum has become a cautionary tale of overtourism. The surge in popularity, fueled by Instagram-worthy scenery, has brought overcrowding, environmental strain, and rising costs. The Guardianreported that locals are being pushed out by developers and despite the thinking that tourism helps local communities, poverty nearly doubled between 2015 and 2020. Local ecosystems, including fragile mangroves and coral reefs, are threatened by unchecked construction and pollution too. The local ruins have implemented stricter rules like no food or drink to limit trash and environmental impact from tourists.

Santorini, Greece

Instagram fame has turned this once-serene island into a tourist hotspot. Narrow streets are perpetually clogged, and locals are struggling with soaring costs of living due to tourism demand. The government has since capped the number of daily cruise ship visitors to keep overtourism at bay.

Cinque Terre, Italy

Known for its colorful cliffside villages and breathtaking coastal views, these once-quiet fishing towns now see millions of visitors annually, way more than they can handle. To combat issues like congestion and cruise ships, local authorities have introduced visitor caps and encourage sustainable travel to protect Cinque Terre’s charm.

Reykjavík, Iceland

Is there anyone not going to Iceland these days? A small country with breathtaking landscapes, Iceland has been overwhelmed by tourists flocking to Instagram-famous sites like the Blue Lagoon and Diamond Beach. It's best to travel during the off season (November to April) and travel to lesser known spots like the Sturlungalaug hot spring.

Maya Bay, Thailand (Phi Phi Islands)

This iconic beach, popularized by the DiCaprio film The Beach, suffered ecological devastation from hordes of visitors and anchored boats. Coral reefs were destroyed, and the beach was closed for years to allow recovery. It has since reopened after a huge revitalization project, but they have introduced visitor caps.

Kyoto, Japan

Traditionally quiet streets of this ancient capital city now teem with tourists during peak season. An increase in litter from tourists has required the city to install more trash bins to handle the crowds, and peaceful geishas are often chased down for photos. To mitigate the problem, Kyoto is considering running special buses to popular sites to reduce overcrowding, and temples and shrines are encouraging visitors to come early in the morning.

Mount Everest, Nepal

The ultimate challenge for adventurers, Mount Everest has experienced overcrowding on the slopes and at base camps, leading to dangerous conditions, with litter and human waste piling up on the mountain. Permits are now harder to get, and stricter regulations for climbers are being enforced.

Dubrovnik, Croatia

The Game of Thrones effect brought an influx of fans to this medieval city. Overcrowded streets and cruise ship arrivals have made it difficult to appreciate its beauty. The local government is taking steps to limit daily visitors and impose stricter cruise ship regulations.

Lisbon, Portugal

Short-term rentals dominate the housing market now, thanks to affordable flights and the digital nomad craze. This has led to skyrocketing rents and displaced locals. Historic neighborhoods are inundated with tourists, making them less charming too. Everything from public transport to waste management struggles to keep pace with the influx. I went in December and it still felt a bit like Disneyland. Douro Valley and Madeira might be more favorable destinations any time of year.
