Stung Treng is located on a high sandy bank overlooking the Mekong River. It is a beautiful place with some historical value. The Ramsar site to the north that connects to Laos is a real treat to explore and several (nearly extinct) Irrawaddy Dolphin pools surround this charming provincial town. You could also easily spend a day here relaxing by the river, watching the sun set and rise over the landscape.
