This is an exciting and delightful recreation. The Pai itself is the longest river of Mae Hong Son originating from mountain ranges in Laos which flows through Pai district and eventually joins the Salawin river in Myanmar, a total distance of 180 kilometres. With an average depth of some 7 metres, the riverbed is mainly pebbled. There are several sectors eminently suitable for rafting past rapids and natural scenery including beautiful waterfalls.

Tour operators in Mae Hong Son town or in Pai district can provide the necessary service, some also able to provide elephant rides. The best time for rafting is from October to March.
