The verdant hills surrounding the town of Kanchanaburi hide numerous limestone caves, many of which have been used as Buddhist and animistic temples over the years. Khao Pun Cave (Wat Tham Khao Pun) is one of the best. Claustrophobic passages burrow into the hill, where cave formations — stalagmites and stalactites — are interspersed with alters carved from the rock, displaying statues of the Buddha, various Hindu deities and offerings left by devotees.
During World War II, soldiers of the Japanese Imperial Army used the caves for storage.
The best way to reach Khao Pun Cave is by bicycle from Kanchanaburi. The cave is located less than half a mile (1 kilometer) from the Chong-Kai War Cemetery.
