Kanchanaburi

Although best known for its sobering role in WW2 history — with sites including the Death Railway, Bridge over the River Kwae (Kwai) and Allied War Cemetery — Western Thailand's Kanchanaburi has plenty to offer tourists wanting to stay a little longer.
The nearby Erawan National Park is home to a number of caves and one of the most popular waterfalls in the country — a 7-tiered series of falls with emerald green ponds and a head which allegedly resembles the Erewan, the three-headed white elephant of Hindu mythology. In the city, visitors can enjoy a Khmer temple ruins tours or explore the scenic River Kwae area, with peaceful bamboo raft journeys down the river available.
