A religious hill complex, Phnom Sorsia consists of a garishly painted Buddhist temple and a karst outcrop riddled with caves. A staircase leads up to the temple, to the left of which is the first cave with a stalagmite resembling an elephant’s head, giving the cave its name – Rung Damrey Sor, or White Elephant Cave.  Farther east lies Bat Cave, filled with thousands of bats. The walk up to the summit leads to a stupa and scenic views.
