Blorenge overlooks the market town of Abergavenny and the villages of Llanfoist, Llanellen and Govilon in the Usk Valley to the north.

The high moorland ridge continues to the south of the minor road at Foxhunter car park and assumes the name Mynydd y Garn-fawr.

The cairn referenced in the title of this southerly shoulder of Blorenge may be that now known as Carn y Defaid which sits on the county boundary at a height of 503m.

A small glacier nourished by windblown snow from the plateau excavated the hollow on the eastern side of Blorenge which is known as The Punchbowl.

[4] Blorenge is situated within both the Brecon Beacons National Park and the Blaenavon Industrial Landscape, a World Heritage Site.

Much of the hill has also been designated a Site of Special Scientific Interest principally for its heather moorland which is important for breeding red grouse.

Some come to see the grave of Sir Harry Llewellyn's famous showjumping horse, Foxhunter, who won Britain's only Gold medal in the 1952 Summer Olympics.

Every November a 'category A' fell race takes place on the mountain starting and finishing at St Faith's Church at Llanfoist.

It has been suggested that the mountain's name may derive from the Welsh plor ('pimple') and relating to Middle English blure ('blister'), or else from blawr ais ('grey ribbed').

The climb is regularly featured in cycle races,[14] and has hosted the finish of the final stage of the Junior Tour of Wales since 1989.
