context_page_description: Mynydd Epynt is an upland area of Mid Wales within the county of Powys, Wales. It is bounded to the south by the upper section of the valley of the River Usk and the Brecon Beacons National Park, to the north by the valley of the Afon Irfon, and to the east by the valley of the River Wye. Its western boundary is less distinct but lies eastward of the A483 Llandovery to Llanwrtyd Wells road. Its character is that of an extensive though dissected moorland plateau lying between 400 and 450m above sea level and whose highest point of 478m is reached at an unnamed rise at OS grid ref SN 961464.
  The south-western part of Mynydd Epynt is known as Mynydd Bwlch-y-groes. The area is drained by several southward-flowing rivers which empty into the River Usk. These include the Cilieni, Nant Bran, Afon Ysgir and Afon Honddu. The Duhonw drains north-eastward into the River Wye. The highest point is a Marilyn.
  The Welsh-language name means mountain horse-path. It can be spelled as Mynydd Eppynt. In earlier times it was known simply as Epynt and is commonly referred to today as the Epynt.
context_section_description: The Ministry of Defence acquired several thousand acres of Mynydd Epynt in 1939.  This now forms the core of the Sennybridge Training Area (SENTA). It is one of the largest military training zones in the UK and is of restricted access owing to the use of live ammunition and explosives. Unsurprisingly this move was a controversial one, not least for those people who were required to vacate their land. The families who left Mynydd Epynt in 1939 were not given any compensation.
