KOH PHANGAN, Thailand -- In the late afternoon sun, a long line of sandals snakes down the beachfront road in Thong Sala, the main town on Koh Phangan, a tourist island in the Gulf of Thailand famed for its scenic settings and laid-back beach life.
Visited by 1 million travelers in 2019, Koh Phangan's primary draw has long been its monthly Full Moon Party, which attracts between 10,000 and 30,000 young revelers a month from around the world to Haad Rin Beach in the southeast corner of the island.
