About Preah Vihear:
Vast Preah Vihear Province shares borders with Thailand and Laos to the north, as well as Siem Reap, Oddar Meanchey, Stung Treng and Kompong Thom within Cambodia. Much of the province is extremely remote and heavily forested. However, large logging companies are doing their best to change this, carving huge tracts of pristine tropical hardwoods out of the landscape. The province remains desperately poor, thanks in part to a disastrous infrastructure where there are no major roads in existence. The ‘road’ linking the provincial capital, Tbeng Meanchey, to Choam Khsant in the north is only passable for half the year, and that’s stretching the definition of passable.
However, Preah Vihear’s future may be brighter, as within the province’s lengthy boundaries are found three of the most impressive legacies from the Angkorian era: the mountain temple of Prasat Preah Vihear, the 10th-century capital of Koh Ker and the mighty Preah Khan. Koh Ker is now easily accessible from Siem Reap via Beng Mealea, but the other two remain difficult to visit, requiring long and tough overland journeys and the distinct possibility of a night in the forest. In the wet season, they are simply unreachable. However, there are plans to upgrade roads leading to each of these incredible locations, which, in time, could ensure the temples of Preah Vihear province become one of the most important stops on a visit to Cambodia.
