Another cave is The Dark Cave, not open for tourists, which is 400 meters long with the ceiling more than 100 meters above the floor and a two kilometre long network of caverns.
The Batu Caves are among the holiest Hindu shrines in Malaysia. Once a year, in January or February, the Hindu Festival at the Batu Caves called Thaipusam is held. The festival is celebrated all over Malaysia and in Singapore. Up to 800,000 devotees and tourists come to the caves during the festival. This is a festival of faith and endurance; it combines the celebration of Lord Subramaniam, the youngest son of Hindu god Shiva, and the union of Pusan and Brihaspati stars.
