Pha Taem National Park
Na Pho Klang, Khong Chiam District, Ubon Ratchathani, Thailand
History Amid SplendourOne of Thailand's least visited national parks, Pha Taem deserves much more exposure. Not only does it boast some awesome scenery -- the views over the Mekong River to Laos from the top of the cliff that dominates the park are incredible -- it also has prehistoric rock painting dating back to at least 1000BC. Other highlights include waterfalls and unique rock formations.
