The limestone hills surrounding Kanchanaburi are famous for their temple caves, an underground communion of animistic spirit worship and traditional Buddhism. Winding arteries burrow into the guts of the caves past bulbous calcium deposits and altars for reclining or meditating Buddhas, surrounded by offerings from pilgrims. Wat Tham Khao Pun is one of the closest cave temples, and is best reached by bicycle. The temple is about 4km from the TAT office and 1km southwest of the Chung Kai cemetery across the railroad tracks and midway up the hill.
