Wat Tham Klong Phen 

This temple is at the foot of Phu Phan mountain, 13 kilometres from town on Highway No. 210 (Nong Bua Lam Phu-Udon Thani), then 2 kilometres on the right. The area was once the site of an ancient Khmer temple that later became deserted until 1958 when Phra Achan Luang Pu Khao Analyo turned it into a meditation centre until his death in 1983. A museum displays his wax figure as well as his personal items. The temple is very peaceful with a large area and covered with shady trees and natural rock formations. It is most suitable for meditation.
