The largest town in Perlis, Kuala Perlis, is a fishing town located at the estuarine delta of the Perlis River. The town is 13km from Kangar.

The population in Kuala Perlis is about 10,000 people. The major industry in this town is fishing. Along the riverbank you will see wooden houses resided by fishermen. Small shops and old warehouses can be found around this area as well.

The visit to Kuala Perlis would not be complete without taking a bite on some of their local fast food like Laksa.

To reach Phuket Island or Langkawi, one should head to Kuala Perlis. There is a ferry terminal here bound to both islands and other coastal towns as well.

Gua Kelam, Kaki Bukit refers to the 370-metre long limestone cave at the small town of Kaki Bukit. Its name literally means "at a foothill (Kaki Bukit) lies a dark cave (Gua Kelam)". Access to the cave is by way of a suspension bridge. The uniqueness of approach, as well as the experience of walking along the bridge, make a visit to this place an intriguing and adventurous experience.

A subterranean stream flows in the limestone range near Kaki Bukit for about a quarter of a mile long. As in other limestone areas, the stream has built a long cavern over the centuries. This physiographic phenomenon was enlarged throughout the length of the underground stream in 1935 by a resident Englishman who saw it as a marvellous way of transporting tin ore from a mine located near the stream entrance through the underground cavern.

A wooden walkway hangs suspended throughout the length of the underground cavern providing a wondrous means of communication from Kaki Bukit to a valley on the opposite end - the Wan Tangga Valley.
