Phnom Sar Sear is a nature and cultural site located about 14 kilometers southeast of Kep city. This mountain is called Phnom Sar Sear because, according to Khmer legend metions above, when Prince Sakor Reach led the troops to this place, he got off his horse and moved furtively ahead of his pursuers along the mountainside, where at that time there was an island to which he fled. Thus, the mountain was called Phnom Sar Sear.

Phnom Sar Sear is composed of three small mountains about 1.5 square kilometers. It is about 40 meters high. The site features two natural caves-Phnom Dorei Sar and Phnom Ach Prochiev-which tourists can explore. In Phnom Damrei Sar cave, there is a beautiful mountain well called Veil Sre Mouy Roy. In the past, this site was also popular with filmmakers.

At the foot of the mountain are a number of small halls where clergymen and nuns meditate. Along the way to the mountaintop, there is a Buddhist pagoda where monks live. On the mountaintop sits a colorful, finely sculpted stupa built in 1964 by Prince Rasmei Sophoan. A place of worship, it also houses a Buddha relic.

The fresh air and beautiful natural scenery make Phnom Sar Sear popular with tourists throughout the year. From the mountaintop, visitors have an excellent view of the rice paddies, the islands and the sea below, as well as the distant mountains. Buddhists go there to pray for good fortune.
