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.
