Every year in late November and early December the River Kwai Bridge Festival is celebrated. A highlight of the festival is the Sound & Light Show, which tells the history of the Death Railway, the Hellfire Pass and the Bridge on the River Kwai. Once the 415 km long Death Railway runs from Thailand to Burma to support there the Japanese defense lines. The festival also includes a big fair at the Bridge on the River Kwai. It's an excellent location for shopping and having some fun there; give the local foods and sweets a try.
