If you’re coming from Pai drive out to kilometer marker 93, you will find a sign that points you to Ban Pam Klang on your right. If you take that road & drive for 8 kilometers you’ll find Pam Bok Waterfall on you right hand side just before reaching Pam Bok village.
You can park your motorbike or car in the small alcove next to the track. Pam Bok Waterfall is a short walk up a narrow track until you reach a high cliff with a small stream running over it. In the wet there is enough water in the pool at the base of the falls to swim in.
