US, Mexico, Italy, Switzerland, Kenya and France are all experiencing a sharp rise in visitor numbers, pushing their cultural and natural landmarks to a critical point. From fragile alpine trails and melting glaciers to overstretched historic districts and coastal regions struggling with unchecked development, each destination is confronting a mix of environmental stress, overcrowding, and community fatigue. Local residents, conservation groups, and policymakers are increasingly voicing concerns, urging for stronger protections before these iconic places lose the qualities that make them globally admired. As tourism continues to surge, the call for responsible travel and sustainable planning has never been more urgent.
As global tourism surges to unprecedented levels, numerous popular destinations are beginning to feel the strain. Rising crowds, environmental damage, and local frustrations have triggered urgent calls for a change in the way we travel. Fodor’s annual “No List” sheds light on these pressure points, urging travellers to reconsider their plans for 2026. The list isn’t about punishing destinations but about raising awareness—helping us understand when a beautiful place needs a break from the overwhelming influx of visitors. Here are eight destinations where overtourism is wreaking havoc, and why it might be time to choose an alternative.
1. Antarctica – A Pristine Wilderness at Risk
Antarctica, the world’s most remote and untouched continent, continues to draw a steady stream of adventurers. In 2023-2024, 120,000 visitors made the journey, and this number is expected to double by 2033. While Antarctica’s majestic landscapes are mesmerizing, it’s a place without infrastructure to support mass tourism. Its fragile ecosystems are under increasing threat, with conservationists warning that the delicate balance could be disrupted by further tourism. For responsible travellers, the message is clear: hold off on visiting for now and allow Antarctica the time it needs to preserve its unique environment.
2. The Canary Islands – A Paradise Struggling to Cope
In the first half of 2025 alone, the Canary Islands welcomed 7.8 million visitors. This surge in tourism has placed a heavy burden on the local infrastructure, natural resources, and social fabric. Rising rents, environmental degradation, and overdevelopment have sparked protests across the islands, with locals arguing that the current tourism model is unsustainable. While tourism is a vital part of the islands’ economy, the residents are beginning to question whether it’s worth sacrificing their quality of life for the sake of mass tourism. The Canary Islands are beautiful, but at what cost?
3. Glacier National Park, USA – A Vanishing Legacy
Once home to 150 glaciers, Montana’s Glacier National Park now only has 27 remaining—and they’re melting fast. With rising temperatures and growing numbers of visitors hoping to catch a glimpse of the glaciers before they disappear, the park is facing mounting pressure. The combination of overcrowding and environmental stress is damaging the park’s fragile ecosystems. In just a few years, the glaciers could be gone, and with them, a piece of natural history. For those planning a visit, it’s worth reconsidering whether it’s better to explore alternative destinations and allow this national treasure the space it needs to heal.
4. Isola Sacra, Italy – Quiet Shores Turned Into Cruise Ship Highway
Isola Sacra, a peaceful island just outside Rome, is facing the threat of massive development as a new mega-port is being planned. The port would accommodate large cruise ships and thousands of passengers, transforming the once-silent coastline into a major tourist hub. The local community, joined by environmental activists, is protesting against the development, warning that the project could destroy the island’s natural beauty. With plans for docking spaces that can handle up to 6,000 passengers, Isola Sacra is at risk of losing its charm and tranquillity. This is a destination in need of time to breathe, not more tourists.
5. The Jungfrau Region, Switzerland – The Strain of Alpine Tourism
Switzerland’s Jungfrau Region is famed for its breathtaking landscapes, but these once-quiet alpine retreats are now under intense pressure. Tourists flock to towns like Interlaken and Grindelwald, eager to experience the Swiss Alps. However, overcrowding has taken its toll on mountain trails, local resources, and the environment. What was once a pristine escape is becoming increasingly strained by mass tourism. As Switzerland faces the challenge of preserving its idyllic landscapes while accommodating growing visitor numbers, the Jungfrau Region is at a tipping point.
6. Mexico City, Mexico – The Gentrification Dilemma
Mexico City has become one of the most popular destinations for travellers, but this popularity has sparked tensions. Gentrification has driven up rents, and the increasing presence of Airbnbs and expatriates is altering the character of once-vibrant neighbourhoods. Protests against rising costs and the displacement of locals have become more frequent, with tourism becoming a point of contention. As tourism continues to reshape the city, Mexico City is becoming a more sensitive destination for visitors. It may be wise for travellers to approach with awareness of the socio-economic issues affecting the local community.
7. Mombasa, Kenya – A Coastal City on the Brink
Mombasa, Kenya’s historical coastal city, is grappling with the pressures of overtourism. With the government targeting 3 million visitors annually, Mombasa is beginning to show signs of strain. Overcrowded beaches, clogged roads, and waste management issues are becoming more common. The rapid, unregulated development is further exacerbating the city’s environmental problems. Mombasa’s charm is at risk of being overshadowed by the very tourism that made it famous. For those seeking an authentic Kenyan coastal experience, it might be time to look elsewhere.
8. Montmartre, Paris, France – A Bohemian Dream Turned Tourist Trap
Paris’ Montmartre district, once a haven for artists and bohemians, now sees 11 million visitors each year—more than the Eiffel Tower. The area’s cobblestone streets, once filled with quiet charm, are now crowded with souvenir shops, caricature artists, and tourists seeking the perfect photo. Local residents are struggling to maintain their way of life amid the influx of tourists, and the once-picturesque neighbourhood is being worn down by overcrowding. While Montmartre’s beauty remains undeniable, the impact of overtourism is clear. The village atmosphere that once defined Montmartre is quickly vanishing.
US, Mexico, Italy, Switzerland, Kenya and France are facing surging visitor numbers that strain ecosystems, city districts, and heritage sites, prompting locals and conservation groups to demand stronger protections. As tourism pressure intensifies, these destinations are calling for more responsible travel and urgent safeguarding measures.
These eight destinations are facing the damaging effects of overtourism. From environmental stress to social unrest, these locations are at risk of losing the very qualities that made them appealing in the first place. While they remain popular travel spots, it is clear that responsible tourism is more important than ever. In 2026, it’s time to rethink our travel choices and consider destinations that are ready to embrace tourism without sacrificing their integrity. Let’s choose to be mindful of the impact we have on the world’s most cherished locations.
