The site is located on the outskirts of Kuala Lumpur but, based on my high-level check, going there with public transport may be a hassle. I went there with rental car and my GPS led me to a very strange place with parking for about three cars and teenagers laughing while taking a bath in a nearby river. I thought I got into wrong location, but after a while I found the start of trekking trail just near the parking. Unfortunately the trail was closed until further notice. Despite the warnings I entered but surrendered after 20 minutes - after heavy rains the trail is really destroyed.
Based on the pictures shown on the billboard at the start the trail should be nice, with caves, shaped stones etc. From the distance the ridge is however not spectacular at all, there are tens of better looking ones in Malaysia. Overall, I am surprised Malaysia put it on T-list in 2017 while the site is totally unprepared for tourists.
