Kanchanaburi is now a major tourist destination in Thailand. In addition to the bridge it attractions include several well-known waterfalls, caves that were once inhabited by Neolithic man, pristine national parks, tranquil rivers, virgin forests, several large reservoirs and activities like fishing, rafting, canoeing, mountain biking, bird-watching, star-gazing, golfing, elephant and jungle trekking, or even living in a bamboo raft. Rafting trips in Kanchanaburi are usually done on large bamboo rafts with a two story shelter that carries up to 20 people. Obviously rafts of this kind are better for negotiating relatively calm stretches of water not Class V whitewater rapids.
