Khao Phra Wihan National Park

Khao Phra Wihan National Park is a protected area in Kantharalak district, Sisaket province, Thailand, that contains numerous ruins of the 11th century Khmer Empire. The park lies 98 km (61 mi) south of the town of Sisaket, at the end of Thai highway 221. Sited on a red stone cliff that is part of the Dângrêk Mountains on the southern edge of the Khorat Plateau, it abuts the international border between Thailand's Sisaket province and Cambodia's Preah Vihear province.
