Belcoo Fault

The Arney River is a small river in County Fermanagh, Northern Ireland, feeding from Lower Lough MacNean and into Upper Lough Erne. It meanders through a wide, flat Glacial Trough between the uplands of Fermanagh, Belmore Mountain and the Cuilcagh Mountains. The valley is characterised by wide flat lowlands enclosed by low hills. The Cladagh River drains into the Arney River. There are six bridging points on the Arney River, five of these are suitable for motorised vehicles, while one is located on private land near to the source of the river.

Belmore Mountain (from Irish Sliabh Bhéal Mór , meaning 'big mouth mountain') is a hill in the townland of Gortgall, western County Fermanagh, Northern Ireland. With a summit roughly 398 metres (1,306 ft) above sea level, it is the second highest point in Fermanagh, the highest being at Cuilcagh on the Northern Ireland–Republic of Ireland border in the south of the county. The historian John O Donovan (1834) states that the indigenous population called the mountain Bel Mor Muintir Pheodachain .Belmore Mountain dominates the skyline in the nearby county town of Enniskillen and gives its name to Belmore Street.

The Cladagh River (from Irish an Chlaideach 'washing river') is a small river in County Fermanagh, formed from three rivers and a number of streams draining off the northern slopes of Cuilcagh mountain, which combine underground in the Marble Arch Cave system. On the surface, the River Cladagh emerges from one of the largest karst resurgences in the UK, before flowing through Cladagh Glen Nature Reserve and eventually draining into the Arney River.

Lough MacNean (from Irish Loch Mac nÉan, meaning 'Mac nÉan's lake') is a large freshwater lake on the border between Northern Ireland and the Republic of Ireland. It is in two parts. Lower Lough MacNean (or Lough Nilly), the smaller eastern lake, is wholly within County Fermanagh (in Northern Ireland). Upper Lough MacNean, the larger western lake, is split between Fermanagh, County Cavan and County Leitrim (in the Republic of Ireland). On the strip of land between the two lakes are the villages of Belcoo (Fermanagh) and Blacklion (Cavan). A river runs between the villages, linking the eastern and western lakes.The shape of Lough MacNean changed during the 1960s when a major draining operation took place; before this, the lake was used for eel fishing, but dredging during the drainage process decimated their numbers.

Boho (pronounced BOH, from Irish Botha, meaning 'huts') is a hamlet and a civil parish 11 kilometres (7 mi) covering approximately 12 km × 7 km (7 mi × 4 mi) southwest of Enniskillen in County Fermanagh, Northern Ireland. It is situated within Fermanagh and Omagh district. This area contains a high density of historically significant sites stretching from the Neolithic Reyfad Stones, through the Bronze Age/Iron Age (Aghnaglack Tomb) and medieval (High Crosses) to comparatively recent historical buildings such as the Linnett Inn. Boho parish has a high biodiversity of flora and fauna due in part to the niches offered by the limestone karst substrata combined with fen meadow, upland heath and acidic bog. The three mountains found within the parish; namely Glenkeel, Knockmore and Belmore provide a landscape varying from high craggy bluffs, with views of neighbouring counties, to low, flat bogland punctuated by streams and lakes. Below this landscape are two of the three most cave-rich mountains in Northern Ireland, featuring the deepest cave system in Ireland at Reyfad Pot, the deepest daylight shaft in Ireland at Noon's Hole, as well as popular caves for local outdoor adventure centre groups at the Boho Caves and the nearby Pollnagollum Coolarkan.
