The traditional Songkran Festival is celebrated all over Bangkok from residential areas to Wat Suthat, Wat Pho and Siam Square shopping district. But the centre of the action remains Khao San Road, a backpacker ghetto that evolves into a cool hangout every April. For a really wet-and-wild scene, Khao San Road is definitely the place to be. Armed with pump-action water cannons and buckets of coloured powder, thousands of fun-lovers will be soaking everything that moves. Starting officially from April 12 though it's likely to get underway unofficially the Friday before, it continues until there is nothing left to soak. Khao San Road and Santi Chaiprakan Park in Bang Lamphu play host to the unofficial International Songkran Festival, the most boisterous of the Asia’s water festivals.
