Stand at the main crossing in Hallstatt, Austria, at midday and the village stops feeling like a village. Around 800 people live there. On a busy day, roughly 10,000 visitors walk through, according to National Geographic — more than a tenfold jump in population, sustained from morning to evening, every day of the season.
That imbalance is overtourism: too many people in one place at one time, enough that residents' daily life and the visit itself both suffer. There is no universal headcount that defines it. What matters is whether the crowd degrades the place — and the short answer for travelers is that you can ease the pressure by picking different seasons, different routes and different bases, without giving up the trip you came for.
What is overtourism, exactly?
The working definition comes from the UN World Tourism Organization, which calls it the impact of tourism that excessively harms residents' quality of life or the quality of the visitor experience. Wikipedia's overview of the term notes it entered common use around 2017, when protests swept European cities including Barcelona, Venice and Palma de Mallorca. A second wave of protests spread across Southern Europe through 2025.
The key nuance: overtourism is not the same as mass tourism. Some destinations host millions of visitors a year and manage fine — London is the standard counterexample. Others with far smaller totals buckle. The difference is capacity, timing and how the destination handles the flow, not the raw number.
It also is not only a city problem. Rural villages, islands, national parks and coastlines all show the same pattern: visitors and residents sharing the same streets, trails, water and housing, with the infrastructure sized for the residents.
Why do hotspots buckle under the pressure?
The core cause is concentration. The French analytics startup Murmuration, which monitors tourism's environmental footprint using satellite data, found that 80% of travelers visit just 10% of the world's tourism destinations, as reported by National Geographic. Everyone goes where everyone went last year. Social media amplifies that, turning single viewpoints into must-shoot stops. We covered a connected angle in Slow Travel: Why Fewer Stops Make Better Trips.
When the crowd arrives, several things happen at once:
- Housing shifts. Landlords convert rentals to holiday lets. Rents rise, residents move out, and whole neighborhoods reorganize around visitors.
- Infrastructure strains. Buses, water, waste and parking were built for locals, not a daily surge of tourists.
- Prices climb for basics like food, lodging and transport — for visitors and residents alike.
- Nature pays. Reefs get damaged by anchors, trampling and touching; trails erode when people stray from official paths.
The scale behind all this is growing. International arrivals peaked at 1.5 billion in 2019, and the UNWTO projects 1.8 billion by 2030. Transport-related tourism emissions are expected to grow 25% from 2016 levels by 2030, per the same UNWTO figures cited by National Geographic.
What are destinations actually doing about it?
The toolkit has grown sharper in the last few years, and some of it now looks drastic. As the BBC reported in February 2026, Fujiyoshida, Japan cancelled its annual cherry blossom festival — an event that typically drew 200,000 visitors — after residents complained of littering and trespassing. Kyoto has banned photography of geisha and restricted access to certain alleys in historic Gion. Fujikawaguchiko erected a mesh barrier in 2024 to block an Instagram-famous Mount Fuji photo spot.
Money is another lever. In 2026 the US introduced a $100 per-person surcharge for international visitors at 11 popular national parks, including Yellowstone, Yosemite and the Grand Canyon, and raised the annual America the Beautiful pass to $250 for non-residents, against $80 for US citizens. Half of all recreation visits to the 433-park system concentrate in the 25 most-visited parks, which is where the crowding sits.
Not everyone thinks fees fix it. "Pricing is not a visitor management plan," Dulani Porter of destination marketing firm SPARK told the BBC, noting that congestion at places like Zion and Yosemite tracks domestic summer travel patterns and limited parking as much as anything. Jamaica, meanwhile, is trying the opposite approach: incentives that pull visitors into off-peak months rather than restrictions that push them away.
Conditions and rules change often — check the managing agency or tourism board before you book, because the fee you read about in January may not be the fee at the gate in July.
How can you travel popular places responsibly?
Here's the practical part. None of this requires skipping the famous places entirely. It requires spreading yourself — in time, in space, and in where your money lands.
- Go in the shoulder season. The same city in late October is a different destination than in August. Fewer crowds, lower prices, and your spending arrives when the town actually needs it. Our guide to slow travel covers how fewer stops makes this easier.
- Go at off-peak hours. Sunrise at a famous viewpoint is not just better light. It moves your visit outside the tour-bus window and out of the queue.
- Take the alternate route. If one trail, beach or alley is overrun, the region usually has a near-equivalent that doesn't. Tour operators are already adjusting — Inside Travel Group shifted its Japan trips toward five under-visited regions including Toyama and Aomori, telling the BBC these are "places that actively want visitors."
- Book licensed, local accommodation. Unlicensed short-term rentals are part of the housing problem — Spain's government fined Airbnb $75 million in December 2025 for advertising unlicensed rentals. Staying in regulated, locally run places keeps your money in the community. Our guide to picking genuinely sustainable accommodations walks through the checks.
- Follow the rules that exist. Time slots, photo bans, trail closures and coach curfews are the destination's attempt at self-defense. Respecting them is the whole job.
Our analysis: the single highest-leverage choice most travelers make is timing. A trip shifted by six weeks does more than any offset or reusable bottle, because it directly reduces the peak that breaks a place.
Does avoiding hotspots actually help anywhere?
Yes — that's the point of "undertourism." The same National Geographic piece describes how less-frequented destinations have plenty of capacity but often miss out on tourism's benefits. When you redirect a trip to a place that wants visitors, the economic upside arrives without the crowding cost. If you're weighing operators for an active trip, our guide to choosing a responsible tour operator covers the questions worth asking, and our eco section tracks the broader sustainability picture.

What the evidence established: overtourism is a capacity problem concentrated in a small share of destinations, and it is worsening as global arrivals climb toward 1.8 billion. What remains unknown: no agreed method exists for measuring how many visitors is too many, and fee-based fixes show mixed results so far. The traveler's lever is real but modest — one trip, spread out well, is a small number that adds up.
