evidence: LOCATED IN THE VILLAGE OF Yatagampitiya in Sri Lanka, Fa-Hien Lena (also known as Pahiyangala Cave) is the largest cave on the island, and one of the largest natural rock formations in all of Asia. The cave was also the site of a remarkable archaeological discovery that dug up human skulls dating back about 37,000 years—the remains of one of the region’s oldest prehistoric human settlements. [...] A long walk and semi-strenuous climb is required to visit the Pahiyangala Cave, but compared to the other historic sites in Sri Lanka, the climb and walk, in this case, is minimal. Located about 40km away from Colombo, this is a close site and is an easy drive too. The place is accessible from Kalutara and Horana and when you take the Piliyandala Bulathsinghala Road and pass the rice fields and villages, you’ll find yourself at the stony path that leads up to the cave’s entrance. The steps in the path are cemented, but you’d find natural stone steps in between, and they must be stepped on carefully as they have jagged edges and can cause discomfort if stomped on. The excavation pit is open to visitors, and if you’re curious, you can walk down the stairs and into the pit and take a look at the digs with your own eyes. Within the cave, you’d find an ancient door that leads you into the bat cave, not like DC, but real bats that can hit you in the face when they fly out, so step in with care!
