When director Danny Boyle released The Beach starring Leonardo DiCaprio, few expected the film to permanently change one of Thailand’s most beautiful coastlines. Filmed at Maya Bay, the movie showcased crystal-clear turquoise water and towering limestone cliffs that captivated audiences worldwide.

Almost overnight, Maya Bay became one of Thailand’s most sought-after destinations. At its peak, the small beach welcomed up to 5,000 visitors and around 200 boats every day. The surge in tourism brought significant income to the region but also devastated the fragile ecosystem. Anchors damaged coral reefs, sunscreen polluted the water, and constant boat traffic disrupted marine life. By 2018, scientists estimated that more than 80% of the bay’s coral had been damaged, prompting Thai authorities to take the extraordinary step of closing the beach indefinitely.

During the closure, conservation teams replanted thousands of coral colonies, restored native vegetation, and even reintroduced blacktip reef sharks, which gradually returned as the waters became quieter. The bay officially reopened in 2022 under strict conservation measures, including daily visitor limits, designated walking areas, and a ban on boats entering the bay itself.

Today, Maya Bay stands as one of the world’s most famous examples of “overtourism,” proving that a single blockbuster movie can transform a natural wonder—and that protecting it sometimes means temporarily keeping people away.
