Overtourism

Why can a place be spoiled by the very people who came to admire it?

Nobody arrives in a small hill town intending to ruin it. Each visitor comes because it is quiet, unhurried, and lived-in — and each is, individually, almost weightless. Yet the towns that get famous for being quiet reliably stop being quiet, and the people who made them famous are the ones who did it.

That is a strange kind of destruction: no vandal, no policy, no malice. Just admiration, at volume. What kind of thing gets destroyed by being appreciated?

Ask what is actually being consumed. Not the cathedral — stone survives being looked at. What each visitor consumes is a share of the uncrowdedness — the ability to stand in the square without queueing, to hear the bells, to be one of few. That commodity behaves like a resource: my use of it subtracts from yours. And nobody owns it, so nobody can charge for it or ration it.

Which puts this in a familiar family. A resource that is depletable but not owned invites the standard trap: the cost of my visit lands almost entirely on everybody else, while the benefit lands entirely on me. Each visitor's arithmetic is sound — one more person in the square really does barely change it — and the sum of sound arithmetic is a square nobody wants to stand in. No individual mistake is required.

But congestion alone would be a mild problem, self-correcting even: crowds put people off, demand falls, the town breathes. Why does it not settle there? Because the visitors change the town's structure, not just its occupancy, and that part does not reverse when the season ends. Follow the money. A flat let to residents at a monthly rent competes against the same flat let by the night to visitors; where the nightly total wins, the flat converts. A bakery serving a neighbourhood competes for the same lease against a souvenir shop serving a queue, and the queue pays more. Neither conversion is a scandal; each is a landlord doing arithmetic. But each one removes a little of the resident population and a little of the everyday infrastructure that residents need to stay — schools with enough pupils, a doctor, a hardware shop.

Now notice what has happened to the feedback. The town's capacity to host rose — more beds, more restaurants, more boats — while its capacity to be a town fell. Visitor numbers do not self-correct against a falling resident population; they correct, weakly and late, only against visitor dissatisfaction. So the loop runs one way: popularity raises returns to serving visitors, which converts housing and shops, which thins the resident community, which leaves the place still more dependent on the visitors whose numbers created the problem. Venice is the standard illustration — the historic centre's population has fallen from roughly 175,000 in the early 1950s to under 50,000 today, and by 2024 the city was charging day-trippers an access fee on peak days, an admission that arrival volume itself had become the thing to manage.

The last step is the honest one: is there a number? A carrying capacity, above which a place is "over"? Not in the way a lift has a weight limit. The physical constraints are real — a bridge is a certain width, a trail erodes at a certain rate, a water supply has a ceiling — but where the acceptable line sits is a judgement about who bears what, and residents, traders, and visitors will place it differently.

The problem is not visitor numbers as such; it is concentration. A number that is unremarkable spread over a year and a region is unmanageable when it lands in one quarter, in one square, in twelve weeks. Most measures that work are measures against concentration — timed entry, cruise berth caps, moving the marketing budget to the shoulder season — rather than against tourism.

The visitors are also not the decision-makers. How many cruise berths exist, whether whole-flat short-term letting is licensed, which sites get promoted: these are choices made by port authorities, councils, and tourism boards. Treating overtourism as a mass moral failing of travellers puts the blame where the levers are not.

The costs and the benefits also land on different people. Tourism income is real and substantial, but it accrues to landlords, operators, and platforms, while congestion, noise, and rent inflation fall on residents — so a destination can be simultaneously richer and worse to live in, which is why aggregate figures settle nothing.

And the standard remedies each have a cost worth naming. Pricing entry rations by willingness to pay, which manages numbers by selecting for wealth. Caps require someone to decide who gets the permits. Dispersal to lesser-known places is often the same process started somewhere else. There is no version of this that is free.

• Why timed-entry and permit systems have worked at single sites, such as Machu Picchu, more cleanly than at whole cities.
• What short-term-let licensing has actually done to rents in the cities that restricted it.
• How a place funds the upkeep of what visitors use when most of the spending flows to accommodation and platforms.
