Ban Phue

This district, which is 42 kilometers north-west of Udon Thani, has an unusual mix of pre-historic cave paintings, fantastic geological formations and Buddhist shrines, the bulk of which are at Phra Phutthabaat Bua Bok, 12 kilometers outside of Ban Phue on Phra Bat hill. The area has been declared Phu Phra Bat Historical Park where nature-loving trekkers may take a hike around the area, which takes around two hours.
