Public transport - Take a bus from Chiang Mai Bus Station to Lampang and there get to songthaew stop as informed further below.

Drive 57 km until you see a sign pointing left to “Chae Son National Park” on route 1252. Continue driving around 8 km until you see a much bigger sign pointing left. Drive another 3 km and the visitor center will be on the right side of the road.

Public transport - There are songthaews operating from Lampang 8 am to 6 pm. Sonthaews are converted pickup/trucks for shuttle service. These leave from a small and narrow side street to Talad Gao Road on the south side of Want River. This small street doesn’t have any name.
