One of the most distinctive caves in Malaysia is a 370-metre long limestone cave near the small town of Kaki Bukit (literally 'foot hill') called Gua Kelam (Cave of Darkness). Located about 33km north of Kangar, the state capital, Gua Kelam Recreational Park is popular for its enchanting 'cave walk' where you can enter from one end of the cave and come out a different end. Gua Kelam is located within the Perlis State Park which borders with the Nakawan Range of Thailand.
