There’s many small caves outside of Kampot city on the road to Kep. They’re really small, but for Cambodia, they’re really big. There’s a sign from the main road directing you to the caves, but you’ll probably have to ask directions, unless you can read Khmer.
The first cave is interesting for another reason.. Drive out of Kampot towards Kep. Turn left after the first (and only) bridge. Go straight. Turn left again. If you continue straight down the road, you’ll end up in an old rock quarry. You’ll see the first caves in back of the quarry. Small, but you might see people climbing up the cave, inside or out. Thanks to Climbodia.
If you backtrack out of the quarry, you can turn right on the first road (about 30 meters outside the quarry) and it’s another 1KM, 3KM, and 5 KM ’till you can find some more caves. One of them is in a Wat…. It’s a nice ride out in the countryside, but bring yourself some food and water for the ride. (They have water, but no ice). At the end of the line, you’ll find Phnom Chhngok. (the pictures at the bottom of this page). To get back to town from here, turn one way and you’re on the road to Kep, the other way, the road to Phnom Penh. (note: if it’s raining and the bridge is washed out, you can still walk to the caves. Get a guide (any kid who speaks some English will help) for a dollar, and they’ll take you there and give you a tour.
A few kilometers out of Kampot, towards Kep, you’ll find a Buddhist Wat, Wat Phnom Sorsia, which has a few nice caves at the top of a small hill
Climbodia has cave and rock climbing tours like no other in Kampot or Cambodia.
