These caves 13km from KL's city centre shouldn't be missed. Guarded by the world's largest statue of Hindu god Murugan and a spate of monkeys, they were discovered in 1878 by American Naturalist, William Hornaday. To get to the caves you have to climb a grand 272 steps. Once inside, the noise of Hindu music and dripping water, along with the sight of the numerous shrines, make this a truly unique experience. Open daily from 7am-9pm; return taxi from central Kuala Lumpur RM40.
