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.

The earliest evidence of settlement at Ruperra is from between around 700 BC and 100 AD, when an Iron Age Hill Fort was constructed along the ridge of Coed Craig Ruperra. The splendid panoramic views from the top of the ridge would have given the site a strategically strong position. Defensive banks and ditches are still visible around the area of the mound, and continuing work on the site will reveal these more clearly. This hill fort lies within what would have been the tribal territory of a people the Romans called the Silures, who were a fiercely independent nation inhabiting the vale of Glamorgan, Gwent and the valleys
