Went here on 5th July, now only post. So lazy.
This place is in Cheras near Persiaran Awana and the entrance to the trail is at the end of Jalan Awana 25. (I think la) There is another trail that does not lead to this waterfall. Also known as Bukit Saga. There is apparently a Gunung Datuk but that is at Seremban somewhere. Dont confuse them.
It was a 1 hour + hike to the falls. It was a nice trek not too hard or too easy. But the waterfall isnt that nice. Very small and quite low.
