There are a number of caves surrounding Kep. The most popular of which is what was a large circular cavern now open to the sky, with its roof having collapsed over a million years ago. Access is through a tunnel at the side of the limestone formation. This cave is next to Kiriseila Pagoda in Kampong Trach, 30km from Kep Beach. 4km on the left before KT is Phnom Salei, and 326 steps take you to the top for a spectacular view of the countryside.

Phnom Sorsir has several caves to explore, the path winding its way up the hill to a stupa atop, with stunning views of the Bokor mountain escarpment. This complex is also known as White Elephant Cave, a reference to the shape of a limestone formation at the base of the main cave. It’s 10km from Kep Beach, turn west of the White Horse Statue, signposted Wat archway after 1.5km

Phnom Ch’nork has Pre-Angkorian ruins set within a limestone cave, its brick structures dating back to the 6th century ancient state of Funan. It’s located 24km from Kep Beach. Turn right 8km west of White Horse Statue.

Good footwear and a flashlight are a must when exploring all of the caves, and be aware of broken stairways, low ceilings and slippery rocks.
