There are several activities for you to do aside from wandering around the canyon. Take a boat ride on the Mekong and look at life on both sides of the river (Laos and Thailand). You can get on the boat at Had Salung (Salung Shore) which will take you to “Mahanatee Si Phan Don”. This area is a natural breeding ground for certain fish. In addition, you can also visit various shores, caves, and odd-looking rocks. - See more at: http://www.thaiticketmajor.com/Travel-News/Sam-Phan-Bok-@Ubon,-The-Grand-Canyon-of-Siam-1696-en.html?hc_location=ufi&la=th#sthash.3BhTzGv7.dpuf
