Cross the Mae Fah Luang Bridge (located just northwest of the city centre) to the northern side of Mae Nam Kok and you’ll come to a turn-off for both Tham Tu Pu and the Buddha Cave. Neither attraction is particularly amazing on its own, but the surrounding country is beautiful and would make an ideal destination for a lazy bike or motorcycle ride.
Follow the road for 1km, then turn off onto a dirt path for 200m to the base of a limestone cliff, where there is a steep set of stairs leading to a main chamber holding a dusty Buddha statue; this is Tham Tu Pu.
Continue along the same road for 3km more (the sign says ‘Buddha Images Cave’) and you’ll reach Buddha Cave, a cavern by Mae Nam Kok containing a tiny but active Buddhist temple, a lone monk and numerous cats. The temple was one of several destinations on a visit to the region by King Rama V in the early 20th century.
