This small town marks the halfway point from Ubon Ratchathani to Khong Chiam and is certainly worth a stop, at least for a lunch break if not for the evening if time allows. Best known for the Kaeng Saphu rapids which lie about 600m south of where the bridge crosses the Moon River, these rapids are best seen between January and May (in the wet season they are under water) and are an extremely popular place for the locals to come and cool off -- you can even hire inner tubes to float down the river and over the rapids.

On the bank of the river there are a selection of open-air restuarants which throw mats down on the shaded grassy banks and ply you with excellent food and ice cold drinks. Try the extremely spicy baby prawn salad or the slightly less spicy som tam. There are no English menus, but the staff are very friendly and will try to at least guess what you want!
