Lying just across the water from Kratie is the island of Koh Trong, an almighty sandbar in the middle of the river. Cross here by boat with a bicycle in tow and enjoy a slice of rural island life. This could be the Don Khong of Cambodia in years to come and attractions include an old stupa and a small floating village, as well as the chance to encounter one of the rare Mekong mud turtles who inhabit the western shore.
Catch the little ferry from the port or charter a local boat (USaround US$2) to get here.
