Nice ascent from Crosskeys, but watch out for very overgrown pathways on the Machen side. Great views from the top!

A small summit above Risca. Known locally as the "Twmp" (the hump), the pimple or the nipple, due to the shape of the mound on the summit.

If you'd like to follow the blue-rated Pwca trail, this is the point where it peels off to the right, leaving the red-rated Cafall and Twrch trails. It's well signposted and you have to stop here to go through the stone wall circle, which also leads onto footpaths and a play area.
