The entire length of Khao San Road is turned into an almighty water fight, and once you're in, you're going to get absolutely wet! There are police checkpoints set up at both ends of the street to confiscate bottles, cans and the white powder that is usually rubbed on people's faces. Don't worry though, you can buy all the alcohol you're likely to need inside one of the many bars that stay open throughout the festival, some with DJs set up inside plastic shelters and podiums for dancing. A word of advice though: be careful on the tiled floors that become like ice rinks because it's a fiarly common sight to see inebriated young tourists slipping, sliding and ending up with their whisky bucket all over the floor.
