Stung Treng is a northern province of Cambodia. It was formerly called Xieng Teng and was once a part of the vast Khmer Empire, then the Lao kingdom of Lan Xang and later the Lao kingdom of Champassack. During the period of French Indochina it was again ceded to Cambodia.
The provincial capital is also named Stung Treng and is an important trade hub with a few hints of Lao influence scattered about, owing to the fact that the Lao border is about 50 km away .
The San River goes by three names, depending on which of the locals you speak to. Some call it the Kong River because the San and Kong Rivers merge together about 10 km northeast of Stung Treng town, confusing people about which name the river should bear. Others call it the Sekong River, which is the combined name of these two rivers.
The San River is fronted in Stung Treng by a nice stretch of paved road. It’s the centre of socializing (as in most Cambodian river towns) in the late afternoon and early evening hours as the locals ride up and down the stretch enjoying the view and each other. Drink and dessert stands spring up earlier to serve the daily merrymaking crowd.
The river port area just in front of the small city park is fairly busy, handling trade between Cambodia and Laos. The ferry across the San River to where National Highway No 7 continues north to the Laos border is also at this pier. The fare is 300 riel per head. We went for a ride on this stretch (2,000 riel for taking a big bike on the ferry), but there is not much to see along the way besides light jungle and some remnants next to the road that was a target of carpet bombing during the Vietnam War years (the road was recently overhauled and is now one of the best in the country).
