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."

Mynydd Epynt (Welsh: [ˈmənɨð ˈɛpɨnt]) is an upland region of Mid Wales, within the county of Powys. It is bounded on the south by the upper stretch of the Usk Valley, on the north by the Irfon Valley, and on the east by the Wye Valley. Its western boundary is less distinct but lies east of the A483 Llandovery to Llanwrtyd Wells road. The area is an extensive plateau lying between 400 and 450m, drained by several southward-flowing rivers that empty into the River Usk; these include (from west to east) the Cilieni, the Nant Bran, the Afon Ysgir (with its two headwaters, the Ysgir Fechan and Ysgir Fawr) and the Afon Honddu. The Duhonw drains north-eastward into the River Wye. The highest point is a marilyn (having topographic prominence of at least 150m) of 478m. Since 1940, Mynydd Epynt has formed part of the Sennybridge Training Area, the largest military training zone in Wales.

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.
