West Baray, is the largest man-made body of water at Angkor. Visitors can hire a boat to take them to the island in the middle where West Mebon temple once stood. Today, only traces of it remain. But the island is a pleasant spot for a picnic or just walking around when water level is low. Alternatively, visitor can also go for a refreshing swim.
As the temple in the middle is in the same style as Baphuon, the baray was probably constructed in the 11th century. The east dyke leads to Ba Kheng temple. Some historian believed that the West Baray could have been a mooring place for the royal barges as well as a reservoir and a place for breeding fish.
