The Klang Gates Quartz Ridge is unique due to its size and the outstanding beauty of its landscape. The ridge comprises elongated craggy stones in the midst of a tropical green forest. It is a gigantic vertical rock slab built entirely of quartz minerals. The 14 metres long and 200 meters wide ridge is believed to be the longest quartz dyke in the world.

It records an incredible history of more than 200 million years. In geological aspect, the ridge has gone through several stages - sedimentation; collision and emplacement that transformed the original sedimentary rocks into metamorphic rocks; and natural weathering and erosion that make the rocks into a beautiful geological monument.

This area is rich with vegetation and surveys show that there are at least 265 plant species thriving in the area. Five of these species are endemic to the area. A National and Wildlife Department survey in 1985 also indicated the presence of a rare animal, the serow.

It also displays four types of quartz formation. Much of it is opaque white or tainted with grey, lined with minute needles or clear hexagonal quartz crystals in some places. Part of the ridge surrounds the Klang Gates Dam and Gombak Forest Reserve.
