One can find Kanchanaburi just a few hours west of Bangkok. This place is known for the bridge on the river Kwai and the nearby Erawan waterfalls. I stayed on a floating guesthouse on the river Kwai and in the evenings I spend my time in the reggae bar enjoying some live music.
I did a day trip to the Erawan waterfalls and the Hellfire pass, a section of the Death Railway where some remnants of the Thailand-Burma railway are still intact. I learned that a lot of people from the Netherlands were also killed while constructing this railway to Burma during World War II.
