The FloatHouse River Kwai Resort
It's all about nature at this splendid floating resort, near Sai Yok National Park. The buildings are made of teakwood and bamboo, with wooden furniture, though there are modern amenities like fluffy bathrobes and wide-screen televisions. Direct access to the river means that guests can swim, raft, or kayak or just kick back with a book on a private sundeck.
