This heavily trafficked half-moon bay is famous (read: infamous) for its full moon parties, when thousands of revelers descend on the beach to dance to house music and alter their states. The monthly party attracts mostly a younger crowd that unfortunately leaves garbage cairns to mark their path. Nonetheless, the beach is located near a beautiful headland and makes for a relaxing stop so long as long as there is some waxing or waning going on.
Where to Stay: There are tons of hostels of highly varying quality near the beach and hotels will fill up prior to the party so booking a room here can be a little tricky. A good bet is the Best Western Phanganburi Resort ($150), which is located in a quiet area and offers a quiet place to relax, or detox — whatever you need.
Getting There: There is a ferry service between Haad Rin and Koh Samui as well as frequent pick-up taxis. Koh Samui has an airport that is serviced predominantly by flights from Bangkok and occasionally by flight from various cities in Malaysia.
