The region where Ubon Ratchathani borders both Cambodia and Laos has been coined “the Emerald Triangle” in recognition of its magnificent green landscapes. Adding to Ubon Ratchathani’s natural appeal, Phu Chong Nayoi and Pha Taem national parks are two of Isan’s most unspoiled and unvisited natural preserves. Ubon Ratchathani, the north-east's largest City, is also a wonderful place to witness the annual candle festival, a charming Buddhist celebration.
