Overtourism — the condition where visitor volumes exceed the social, environmental, or infrastructural carrying capacity of a destination — now affects over 200 cities and natural areas worldwide. The phenomenon has prompted a wave of innovative management interventions.
The Scale of the Problem
Barcelona receives 32 million tourists against a resident population of 1.6 million. Venice hosts 30 million annual visitors in a city built for 55,000 residents. Dubrovnik’s Old Town, with a carrying capacity estimated at 8,000 people, routinely hosts 15,000 daily visitors during peak season.
In natural areas, the problem is equally acute. Iceland’s Golden Circle route received 2.3 million visitors in 2025 — a 600% increase from 2010 — causing trail erosion, vegetation damage, and strain on waste management systems.
Economic Instruments
Venice Entry Fee — Venice introduced a $5.50 day-tripper entry fee in 2024 for visitors not staying overnight. While criticized as too modest to deter visitors, the fee generates approximately $40 million annually earmarked for infrastructure maintenance and resident quality-of-life improvements.
Bhutan’s Sustainable Development Fee — Bhutan charges international visitors $100 per day (reduced from $200 in 2023), limiting visitor volumes while generating conservation and development funding. The country received approximately 150,000 visitors in 2025 — deliberately modest by regional standards.
Amsterdam’s Tourism Tax — At 12.5%, Amsterdam levies the highest tourism tax in Europe. The city has simultaneously restricted new hotel construction, banned vacation rentals in the city center, and removed the iconic “I amsterdam” sign to discourage mass selfie tourism.
Technology-Enabled Visitor Management
Real-time visitor density monitoring using mobile phone data, entry-gate counting, and satellite analysis is enabling destinations to implement dynamic management. Dubrovnik displays real-time crowd density on digital screens at city gates, encouraging visitors to delay entry during peak hours.
National parks in the United States and Europe are adopting timed-entry reservation systems that distribute visitors throughout the day, reducing peak-hour crowding while maintaining total visitor access.
Natural Area Carrying Capacity
Carrying capacity determination for natural areas is advancing from crude visitor number caps toward sophisticated frameworks that account for spatial distribution, temporal patterns, activity types, and ecosystem sensitivity.
The Galapagos Islands represent the most comprehensive carrying capacity management system, with island-by-island visitor limits, mandatory guided access, and real-time monitoring of wildlife disturbance indicators.
Outlook
Overtourism management will become a core competency for destinations worldwide as post-pandemic travel recovery pushes visitor numbers to new highs. The destinations that implement intelligent visitor management earliest will maintain both environmental integrity and visitor satisfaction, while those that delay action risk irreversible degradation of their core tourism assets.
