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

The Garth has a nice flat top with views across the valleys. Lots of sheep grazing too (March). Also a number of mounds provide some cover from the wind if a break is in order

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.

High above the A470 to the north of Quaker’s Yard, the Giant’s Bite is a dramatic gap in the skyline quarried from the ridge top at the former Cefn Glas mine and quarry. ❤️👌 The site was intensively grazed up to the mid-1990s when a large belt of native trees were planted on the lower slopes. These trees are now maturing and have helped to heal the visible mining scares. The shales forming the upper soil horizons support a wide variety of native flowering grassland species including wild strawberry, cowslip, foxglove and wild thyme, and the site is increasingly becoming re-vegetated by scrub species. Incredibly Fine views of the Taff and Cynon valleys are afforded from the summit ridge, while the line of the former Glamorganshire Canal is also discernible.
