Chiang Dao Town is situated on the Ping river. The river is relatively gentle most of the year and lends itself easily to safe and enjoyable bamboo rafting. White water rafting it is not, but it is a relaxing float down a beautiful river, with a few faster flowing sections adding some spice. The playful pilots(!) ensure fun is had by all.
The rafting is often included in one day tours from Chiang Mai along with Elephant rides.
