Batu caves are well known for their numerous macaques, which visitors feed - sometimes involuntarily

As you walk up the stairs you are greeted by hundreds of monkeys which is just amazing! Be careful of raiding monkeys, don't carry food and drink openly up the stairs! If you don't want to interact with monkeys then don't snack on anything whilst you walk and they won't come near you. Monkeys may also pose a biting hazard to tourists as they can be quite territorial.
