Why go

East of Kep the countryside rises into a scatter of limestone hills, jagged and green, riddled with caves. Phnom Kampong Trach is the most dramatic. A path leads through a tunnel into a hidden valley ringed by cliffs, with caves opening off it, a reclining Buddha in one chamber, and holes in the rock where the sky shows through.

Phnom Sorsia, closer to Kep, is smaller but lovely: steps climb to a pagoda, and inside the hill are caves with formations that pilgrims identify as a white elephant and other sacred shapes.

Together they make a full and varied day, with pepper farms and a lunch of crab in Kep easy to add.

The story

The karst hills of southern Cambodia are a continuation of the limestone landscape that runs across the border into Vietnam’s Ha Tien. Over millions of years, water dissolved the rock into caves, arches and sinkholes, and people have used them as shrines for centuries.

Phnom Kampong Trach has a darker history too. During the war years the caves served as hiding places and military positions, and older villagers remember the fighting here. Today the atmosphere is peaceful, and local children guide visitors through the passages.

At Phnom Sorsia, the main cave is often called the White Elephant Cave, after a pale stalagmite said to resemble the sacred elephant of Buddhist and Hindu tradition. White elephants are symbols of royal power and good fortune throughout mainland Southeast Asia.

Many caves contain small shrines, statues and offerings left by pilgrims. They are living religious sites, not just natural attractions, and families come here on festival days to pray and picnic.

Getting there

Phnom Sorsia is on the main road between Kampot and Kep, a short detour from either. Kampong Trach is further east, roughly an hour from Kampot and less from Kep, toward the Vietnamese border. Roads are mostly paved, with dirt tracks at the end. A driver or tuk-tuk for the day is the easiest option.

A suggested plan

1. 8:00 amLeave Kampot; stop at Phnom Sorsia, climb to the pagoda and the White Elephant Cave.
2. 10:00 amContinue east to Kampong Trach; walk through the tunnel into the hidden valley.
3. 11:00 amExplore the caves and the reclining Buddha with a local guide.
4. 12:30 pmLunch in Kampong Trach town or ride on to a pepper farm.
5. 3:00 pmReturn via Kep for the crab market and sunset.

Where to stay

Kep is the closest comfortable base. Kampot works well too; it just means a longer day.

Good to know

• Hire a local guide at the caves; they know the safe paths and the stories.
• Bring a torch and shoes with grip.
• Cover shoulders and knees at the shrines.
• Carry water; there are few shops near the caves.
