The Phrai Sawan falls are hidden in the middle of the magnificent jungle covering the sides of Khao Bantat, one of the region's mountains. 4.5km in length, and with 17 separate tiers, they tumble down impressively through this verdant landscape. It's possible to reach them along a footpath, although the most exciting option is a descent by kayak. This adventure is suitable for everyone as the gradient is gentle and risk-free, and if you rent a kayak here you'll be given some simple and sound advice on how to enjoy and make the most of your trip.
