The first sight that hits you when you approach the site (07:00-21:00, free admission) is the massive statue of Lord Murugan, a particularly important deity for Malaysia's Hindu community.
Next to the statue are the 272 steps leading up to main caves of the temple complex. After the ordeal by steps, you are faced with the 100-metre high Cathedral or Temple Cave. After another set of steps is a smaller cave, which is bathed in light from the tree-lined gap in the ceiling above. The best (and worst) time to visit Batu Caves is during the Hindu festival of Thaipusam, when the site is thronged by several hundred thousand worshippers.
The caves are located right next to a KTM Komuter station (2 ringgit from KL Sentral).
