Bamboo bungalows moored on the Chao Phraya and River Kwai offer one of Thailand's most atmospheric accommodation experiences.
Most famous in Kanchanaburi — bamboo or wood platforms over the water; sleep to the sound of the river; basic but magical.
A handful of floating accommodation exists near Bangkok on the Chao Phraya — more private and more expensive than the River Kwai versions.
Basic amenities (fan, mosquito nets, shared bathrooms at budget options); the experience is the point, not the facilities.
Through Kanchanaburi guesthouse operators; prices 400–1,500 THB per night depending on facilities and location.
