The ground of Thailand is mostly limestone that is quite soft compared to other stones and water washes it out easily, creating caves. You will find many caves around Thailand. If you just have the time to visit One Thai cave, make it this one.
Located 3km north of Phetchaburi.
There is a road that goes straight there. In front of the hill where the cave is, it divides into 2 lanes, one goes right, the other left - and then there is a very small road going straight up the hill. Big buses can't get up there and you have to walk (10 minutes) or take a taxi. If you have a car, drive straight up, there is a parking space. Take care of the monkeys that are around here.
You climb down the steep stairs into the cave. The sun is falling through holes in the ceiling.
Especially nice to see them is between 11a.m. and 2 p.m. when the sun lights up on the golden Buddha statues (see picture).
