I visited in a very hot day on March 2019. I actually stay not far from the quartz ridge (around 6 km) where I get to see it everyday from my condominium balcony. But I never have time, and most importantly, friend with the same interest to discover this interesting geological formation. So only recently I managed to tick off this tentative list. 

There are two entry points to start off depends on you fitness. You can look for Kaki Bukit Tabur (West) on the GPS as this is the easy trail and you can go for the East one for advanced climbing. After ascending for around 10 minutes through the forest, you will find a lot of quartz on the ground, all over, and actually this will be the trail you'll follow on the rest of your hike. Some of the quartz are quite massive, while the others are like little crystal-like formation. Make sure you have good hiking shoes as some of the surfaces are quite sharp. Do bring a lot of water with you as there is no much shelter especially reaching the top when the sun is so hot.

You will see the Klang Gates Dam on your way up. This is the first dam in Malaysia for water supply. We also saw many species of birds, squirrels, some big ants and gibbon howling. The trail is marked by numbers sprayed on the wall so that you know how far you've got into. The trail is about 2.6 km and it can take up to 4 hours hiking the whole circuit. In our case, we turned back the same way after reaching the top, instead of continuing to the other side.

As the longest quartz ridge in the world, it has its own OUV in science and geology. The forest around provides a good example of how certain species adapted to this kind of rock formation. Compare to those karst formations and volcanic rocks which are quite common around the world, Gombak Selangor Quartz Ridge is something different. So I think it deserves to be listed as a WHS.
