Sited on the banks of the River Kwai, the town is most famous for its role as a POW camp in World War II and for its bridge, whose destruction by the Allied Forces was immortalized in Davis Lean's movie. There are plenty of sobering World War II sights in the town, as well as a reasonable range of trekking, rafting and cycling options that make the most of the fine river scenery, plus some appealing rafthouse accommodation too  so the hiking is not difficult. Most treks last two to four days and feature nights in the villages, as well as an elephant ride and river rafting. The main trekking centres are the northern cities of Chiang Mai and Chiang Rai , but routes out of both are hugely over subscribed, so it's better to start from Mae Hing Sin, Pai, Kanchanaburi or Umphang instead, where trails are quieter and more rewarding.    葵芳工廈 葵芳租盤 葵芳辦公室 Here you can sleep in a tree house under limestone karst, wake to the sound of the hooting gibbons, and take an adventure tour via waterlogged caves and jungles trails to a lakeThe ancient Khmer temple of Phanom RungThis exquisite pink sandstone complex was built in the tenth century as a blueprint for the Angkor temples across the border in Cambodia   Thai massage
