Traditionally, Preah Khan of Kompong Svay district has been the toughest of the remote Angkorian temples to reach. Even now getting there at the peak of the wet season is almost impossible, and the best time to visit is between January and April when the trails are dry. It's located some 93km north of Kompong Thom and 64km south of Tbeng Meanchey in Preah Vihear Province.
Most locals call the temple complex Prasat Bakan but it's common name is Preah Khan of Kompong Svay. Covering almost 5 sq km, it's actually the largest temple enclosure constructed during the main Angkor period, dating from the 9th to 13th centuries. The central tower at Prasat Preah Stung is adorned with large enigmatic faces and the central area of Preah Khan is overgrown by forest and has been badly damaged with many towers collapsing. Some of this was caused by severe looting at the site. If you are looking for a remote temple complex, then it doesn't get much more remote than Preah Khan.
