Head out to Kanchanaburi, Thailand's third largest province, located west of Bangkok, and spend a day learning about the turbulent history of the area. You'll first visit the War Cemetery, the main burial ground for prisoners of war during the Japanese occupation in the early 1940s, and the JEATH War Museum where casualties from the construction of the notorious Burma-Siam railway are commemorated. Next stop is the bridge over the River Kwai, a historical landmark that is part of the Death Railway. The history of the bridge is well known, as it was part of the railway lines in World War II and had seen its share of conflict and bloodshed. It also served as inspiration to the novel by Pierre Bouelle chronicling the horrific events that unfolded, which was later adapated into a Hollywood movie. If you opt for a private tour, you’ll get a chance to ride a boat across the River Kwai before having your lunch and departing for Bangkok in the afternoon.
