Crystal Cave is a very small cave located in a hillside past a now abandoned quarry at the Batu Caves. It differs greatly from the rest of the caves in the hill in that its walls are covered with crystals of all sorts, in the most fascinating shapes and patterns, and it is obviously considerably younger because there are very little signs of re-erosion, unlike the other caves in the hill.

In this cave, while photographing the formations, I also conducted some I conducted some photographic experiments.
