Sangkhla Buri is an idyllic place off the tourist trail, although it is popular with Thais who come for relaxing weekends away or to party in the floating houses.
Away from the main town, across a wonderful rickety wooden bridge, is Wangka (also known as Monside). The village was founded by Luang Phor Uttama in 1949 after he fled Burma with 60 other Mon families. Uttama stayed there until his death in 2006. Alcohol is not permitted to be drunk in public in Wangka and doing so would be hugely disrespectful. Many of the villagers speak Mon as their first language, so don't be surprised if they cannot understand Thai. An easy word to remember is "dangoon" for "thank you".
