Kaeng Khut Khu
With the mountains making an attractive backdrop, this famous bend in the Mekong and its small set of rapids is a popular stop. The surrounding park has a bevy of vendors selling má·prów gàaw (coconut candy), the local speciality. This is also a good place to try gûng-paa (crispy fried shrimp), which looks a little like a frisbee, and gûng đên (dancing shrimp), little bowls of live shrimp. It's 5km downstream from town; túk-túk drivers charge 100B per person
