Gua Kelam

Gua Kelam is a limestone cave system located in Kaki Bukit near Padang Besar in Perlis, Malaysia's northernmost state. Known as the Cave of Darkness, it features a 370-metre illuminated walkway through a former tin-mining cave carved by an underground river. Notable for its stalactites, stalagmites and historic mining heritage, it is managed as a recreational park within Perlis State Park and is one of Perlis's most visited natural attractions.

Visitors can expect a walk through a well-lit limestone cave along a wooden boardwalk and suspension bridge following an underground river. The cave interior displays stalactites, stalagmites and rock formations illuminated for viewing. The route is about 370 metres from one entrance to the other, with a landscaped park, picnic areas and small stalls outside. An extension, Gua Kelam 2, offers a more adventurous guided cave experience with darker passages and stream wading.

Gua Kelam was a tin-mining cave from the 1920s until the 1970s. Miners used the underground river flowing through the cave to transport tin ore, constructing a wooden walkway and channel system. Mining ceased in the 1970s and the cave was later developed as a recreational and tourism park within Perlis State Park, preserving evidence of its industrial heritage.

Known locally as Cave of Darkness (Gua Kelam), the cave is a well-known natural landmark in Perlis and an important recreational site for local communities. It is part of the Perlis State Park geotourism area showcasing the state's limestone hill landscape and former mining culture.
