Cactus Bar
A busy place that tends to play r'n'b, pop and all the other chart rubbish that you can hear in any cheesy nightclub the world over. serves its purpose though as it separates the hardcore of ravers from the annoying "spring break rules!" types.
Drop Inn Bar
At the top end of haad rin is one the biggest bars on the beach. cocktails are cheap, they have plenty of beach seating and great fire shows. music is generally commercial dance mixed in with house. one of the best music selections on a regular night.
Coral
Pool parties to give some craziness on nights where there isn't some lunar celebration happening. Free taxis cruise the town to take you there. Don't arrive too early - some people got on the taxis at 7pm expecting a party to find hotel residents eating dinner and swimming at sunset. Lots of sweaty, luminous dancing on tables and questionable activities in the pool. Not quite full on Full Moon madness, but certainly memorable.
If you're after party heaven you can't do better than Haad Rin. It is most popular one night a month - the night of the Full Moon Party. Every bar is hopping, the beaches packed with trance, dance, buckets, and various other suspicious substances. However, if the sight of thousands of bottles and other trash repulses you, make sure you leave the beach area before the sun comes up, or grab a garbage bag and help tidy up a little.
Mellow Mountain
Built into the side of a cliff. after a precarious ascent up the stairs, expect to find 'special shakes' the "happy shake" is the house special and a very chilled out, laid back atmosphere - perfect if you want to escape the bustle of the beach party.
Vinyl Club
Is more for dancing to techno, but serves drinks as well. right next door is zoom bar which offers more of the same.
