Every month, on the night of the full moon, pilgrims pay lunar tribute to the party gods with trance-like dancing, wild screaming and glow-in-the-dark body paint. For something mellower, the west coast has several excellent bars, where you can raise a loaded cocktail glass to a blood-orange sunset from a hilltop or over mangrove trees at the water's edge. Thong Sala has as a couple of decent bars too.
Hat Rin is the beating heart of the legendary Full Moon fun. When the moon isn’t lighting up the night sky, party-goers flock to other spots on the island’s south side. Most party venues flank Hat Rin’s Sunrise Beach from south to north.
