To reach the Playa del Amor on the Marieta Islands, you swim through a short tunnel carved by the Pacific into volcanic rock, then surface inside a collapsed crater open to the sky. Sand rings the interior. Waves lap gently. The effect is of stumbling into a private world, a pocket of coast hidden inside the island itself. When photos of this hidden beach went viral around 2015, tourist numbers exploded from 27,500 visitors a year to more than 127,000. By 2016, boats were dropping 2,500 people a day onto an island the University of Guadalajara determined could sustain 116 without degradation. The Marieta Islands became a case study in what happens when a fragile place becomes famous overnight.
