This limestone cave complex is about 10km north of Nan and is part of a relatively new wildlife reserve. Some 17 caves have been counted, of which nine are easily located by means of established (but unmarked)trails.
From Nan you can catch a bus or sŏrng·tăa ·ou bound for Pua or Thung Chang; it will stop at the turn-off to the caves for 30B. The vehicles leave from the bus station.
