Yajagama Cave is a former river cave with a single huge passage. The cave drained toward the sea, and so the cave end in a valley where formerly the water which came from the cave was flowing to the sea. Today the cave is dry and the drainage is one level deeper. The cave has some nice speleothem but actually it is famous for various endemic troglobionts which were found in the cave. Beneath bats the cave houses various insects and crabs.
Yajagama Cave was developed as a show cave with a trail, but for some reason without light. Probably because there are not enough visitors to make a real show cave profitable. So there is a huge explanatory sign at the netrance and visitors can see the cave on self guided tours.
