The cave, also called Pahiyangala, is about 5 km from the Kalutara district. You can check with your Kalutara hotel about organising a tour or get recommendations for good tour groups you can join. Located in a village called Yatigampitiya, the cave is named after a legendary monk, Faxian, who is said to have resided there many centuries ago; there is no architectural evidence to prove the monk used the cave as his residence, but you will love listening to the legendary stories woven around his existence. One of the largest caves in Sri Lanka, its altitude is 400 feet. The place is a popular site, especially for school field trips, and lovely enough to enjoy a casual picnic once done exploring the 200-foot long cavern where prehistoric human remains dating back 37,000 years were discovered.
