Batu Caves is not just about the 272 steps and the Hindu temples at Temple Cave – there is also the Dark Cave where visitors can explore the fascinating cave ecosystem with a guided educational tour. The cave is at least 100 million years old and the limestone that surrounds it was originally formed from shells and coral, from when this entire area was underwater.
The cave is also home to millions of both fruit- and insect-eating bats where their droppings (also known as guano) supports an ecosystem within the cave, with cockroaches, spiders, crickets, snakes and other creepy crawlies living off either the guano, the bats themselves or each other.
As you climb up the 272 steps towards the Temple Cave, you will find that at step 204, a path branches off to the Dark Cave. Follow the path and right at the entrance into a very dark cave, there are registration tables where visitors can sign up for the tour. You will also find a mini-exhibition of the bats you can find the Dark Cave.
For RM 35 (Adult), you can sign up for the Dark Cave Educational Tour – you don’t have to bring any special equipment for the tour as torchlight and helmet will be provided.
Just make sure you wear comfortable shoes and clothing and keep yourself hydrated as the tour is about 45 minutes long and the cave can get quite hot at times (with temperature of 27º -29º Celsius and 85-90% humidity year round).
