The Full Moon Party
The Full Moon Party is the reason most first-timers have heard of Koh Phangan at all. Once a small gathering on a quiet beach, it has grown into a monthly all-nighter that pulls travellers from across the world to one curving stretch of sand in the island's south-east corner.
This page is the practical, no-fluff version: where it actually happens, the simple lunar logic behind the dates, how to get there from wherever you're staying, what the night is really like, the smaller satellite parties around it, and the honest safety stuff nobody puts on the flyer. The next date is shown dynamically at the top of the page, so you're always looking at the upcoming one.
