Khao Phra Wihan is a national park two hours south of Ubon Ratchathani. It sits on a 500m cliff, nearly vertical, with stunning views of Thailand and nearby Cambodia. But they made a mistake when documenting the border between Thailand and Cambodia, so the park is on the Thai side but the important Preah Vihar temple in it ended up in Cambodia. The two countries actually went to war over that a while ago.
It’s peaceful now but access to the temple is forbidden. That part of the park is filled with soldiers, sandbagged guard posts, and endless spools of razor wire. But even without access to Preah Vihar it’s a beautiful park.
