Ubon Ratchathani or Ubon for short is a large province in the lower part of Isan, the North East of Thailand. Little visited by foreign tourists, the province bordering Cambodia and Laos is dotted with mountain ranges and several national parks. Ubon’s history goes back thousands of years; traces of ancient man can be found at Pha Taem National Park where rock paintings on cliffs show scenes of prehistoric life. The province’s capital city Ubon Ratchathani town is located on the banks of the Mun river, which flows into the Mekong river at the Thai - Laos border.
