Thala Barivat is a historical site located in Thala Barivat district, about 4 kilometers north of Stung Treng provincial town. To reach the site, travelers must cross the Sekong and Mekong rivers. There they will find Preah Kor temple, a brick structure constructed in the late 7th and early 8th centuries during the reign of King Jayavarman I. In front of the temple is a large statue of Preah Kor.

Near Preah Kor statue, there is a 10-meter-square yard where every year the Kuoy hill tribe engages in Veay Khel. The four-day games, which are part of a Kouy festival, are held two or three weeks before Khmer New Year.

There are many small, ancient temples near Thala Barivat, but most of them, such as Prambuon Lveng temple, Srei temple and Angkor Khmao temple have been heavily damaged over time.
