Overtourism Hotspots: Destinations to Reconsider in 2026

As British holidaymakers initiate planning escapes for 2026, popular destinations like the Canary Islands, Antarctica, and Mexico City have been flagged as places where tourism is placing undue pressure on the environment and local communities. Travel experts suggest that visitors would benefit from choosing alternatives or planning trips with a focus on sustainability and local wellbeing.

The Rise of Overtourism

Overtourism – the result of too many travelers overwhelming local infrastructure – is becoming a global concern, impacting everything from housing prices to fragile ecosystems. Fodor’s Travel Guide’s annual No List for 2026 highlights destinations where tourism growth is outpacing communities’ and environments’ capacity to adapt sustainably. Tourists, business travelers, and adventurers are urged to rethink their plans to help ensure long-term access and positive experiences for all.

Why These Destinations Are Being Reconsidered

Fodor’s No List is designed not to ban travel, but to encourage reflection before booking trips where tourism has grown unsustainably. Places on this year’s list are experiencing pressures such as crowded streets, stretched public services, and environmental degradation due to heavy visitor numbers.

Canary Islands (Spain)

A favorite winter sun spot for British tourists, the Canary Islands – including Tenerife, Gran Canaria, and Lanzarote – have reached a saturation point where local services and infrastructure struggle to support the influx. Residents have protested against overcrowding, rising housing costs, and environmental impacts linked to tourism growth.

Antarctica

Once the pinnacle of remote adventure travel, Antarctica faces pressures as visitor numbers increase and fragile ecosystems are exposed to strains. The Antarctic Treaty requires visitors to have minimal environmental impact, yet increasing cruise and flight access has raised concerns about pollution, disturbance to wildlife, and disease transmission.

Mexico City (Mexico)

Mexico City is seeing tourism-driven changes to housing markets and neighborhood identity, contributing to gentrification and resource strain. Business travelers and digital nomads, once praised for boosting urban economies, are now part of conversations about responsible urban travel and support for sustainable local businesses.

Other Destinations on the List

Additional destinations highlighted by Fodor’s 2026 ‘No List’ include:

• Mombasa (Kenya): Growth in cruise and resort tourism has contributed to congestion, waste management challenges, and strain on marine ecosystems.
• Montmartre (Paris, France): Sheer visitor numbers are transforming living spaces and pushing up prices.
• Glacier National Park (USA): Climate change and visitor numbers threaten dwindling glacial landscapes.
• Isola Sacra (Italy): Facing infrastructure strain due to concentrated visitor growth.
• Jungfrau Region (Switzerland): Experiencing environmental fragility caused by concentrated visitor growth.

What Overtourism Means for Travelers and Local Communities

Overtourism – where visitor numbers exceed what a destination can sustainably handle – leads to challenges such as:

• Congestion and longer wait times for transport and attractions.
• Environmental degradation, especially in fragile coastal or ecological areas.
• Higher living costs for locals due to housing demand from short-term rentals.
• Strain on local services, like waste management and public transit.

These issues impact both short breaks and extended trips, forcing travelers to rethink not just where they travel, but when and how they explore.

Impact on Tourists and Business Travel

For Leisure Travelers

• Crowds and queues: Popular sites may be less enjoyable during peak season due to congestion.
• Accommodation costs: Prices in high-demand areas can be elevated by short-term lets dominating the housing market.
• Environment: Natural sites like Antarctica and Glacier National Park require careful planning to minimize impact.

For Business Travelers

• Timing: Business travel calendars should avoid peak visitor seasons to reduce hotel and transit delays.
• Accommodation strategy: Booking early can secure better rates and support local accommodations outside congested hubs.
• Community engagement: Choosing locally operated services benefits communities rather than large global firms alone.

Quick Tips for Responsible Travel in 2026

• Check Official Travel Guidance: Use national tourism boards and local government sites for updates on capacity limits and travel advisories.
• Choose Off-Peak Seasons: Visit iconic spots when crowds are lower to spread tourism pressure.
• Support Sustainable Options: Book eco-friendly tours and locally owned accommodations.
• Explore Alternatives: Consider lesser-visited destinations for a more authentic experience.
• Respect Local Culture: Learn basic customs, support compact businesses, and reduce waste during your stay.

Planning a Responsible Trip: A Step-by-Step Guide

1. Research the Destination: Look up overtourism data and sustainability ratings before choosing.
2. Set Your Travel Time: Off-peak visits reduce stress on both travelers and hosts.
3. Identify Sustainable Operators: Prioritize tours with environmental or community certification.
4. Book Early and Smart: Plan transport and accommodation well in advance to secure stable prices.
5. Pack Responsibly: Bring reusable items to reduce waste and respect local ecosystems.
