There are many different places around Bangkok where you can celebrate Songkran this year. The most popular places for the water fights will most likely be Khao San Road and Silom Road. However, if you want to see a more traditional side of Songkran, then I suggest that you head to the temples.
Many of the Bangkok temples are having special activities for Songkran. Last night I headed to Wat Pho which is the home of the Reclining Buddha. Every day this week, until Friday 15th April 2011, they have different cultural shows in the courtyard in front of the Reclining Buddha building. These start at 4 p.m. and run until 5:30 p.m.
In addition to the shows, there is also an old-style Thai market where you can buy an assortment of traditional Thai food. This is a great opportunity to taste some of the delicious Thai food and also experience Thai culture from the four regions. While you are at the temple you can also make a “sand pagoda” to pay your respects.
