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.
