Gua Batu Cermin or Mirror Stone Cave in English is an area with approximately 10 hectares filled with huge rock formation. The rock is looking like basalt type of rock, black color and hard.
It is believed to be an area covered with sea water in the past as there are rocks and skeletons of turtle and fish still sticking on the rock wall.
Why is it called Mirror Cave or Batu Cermin then?
There is no mirror in it! It is called mirror because there is a little light of sunshine comes through a hole in the dark tunnel and then bounces on the stone walls that again reflect small lights to other areas inside the cave like a mirror. It is like you point your flashlight towards a mirror in a dark hole and then you will get a light in it. This is why this site is called mirror cave.
To get in the place to see this ‘mirror-like-tunnel’ you will explore the inside part of the rock. The feeling being in the rock has a great feeling of an adventure.
