The Epynt Way is a long-distance path created by the Ministry of Defence in 2004 around the perimeter of its 'Sennybridge Training Area (SENTA)' and artillery range on Mynydd Epynt in Powys, Wales. There is, understandably, virtually no public access across the land used by the MoD, pre-existing public rights of way and public roads having been closed, with only one or two exceptions. The establishment of the Epynt Way, section by section in recent years has gone some way to compensating for that reduction in public access across the area.

Garth Bank Quarry is a Site of Special Scientific Interest in Brecknock, Powys, Wales. The Countryside Council for Wales describes the significance of the quarry as follows: "The rocks in this quarry are siltstones and pebbly sandstones of late Ordovician and Early Silurian age, approximately 440 to 445 million years old. The rocks provide an insight into the environmental conditions at the boundary between the Ordovician and Silurian Periods. The oldest rocks in the quarry comprise late Ordovician siltstones. These contain fossilised remains of brachiopods, a marine sea-shell. After a break in deposition these siltstones are overlain by pebbly, rippled sandstones which range from very late Ordovician to Silurian in age."
