There are over 200 caves in total, with continuous archaeological work going on, as many very old human remains have been found in the caves, plus other evidence that some of the first settlers on Palawan lived in the caves.
It was a fascinating little trip in a beautiful place. A good path has been built around all the cliffs and steep hills, but I have no idea how the first people to live there got into the high caves or found them... I guess by sea as some of the caves go down to the water. Click on the pic to see an album of more photos.
