Belcoo Fault is a geological fault in County Fermanagh, Northern Ireland.

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.

Abohill railway station served Abohill in County Fermanagh, Northern Ireland. The station opened in June 1886. Passenger services were withdrawn on 1 October 1957.

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.

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.

Moylehid (from Irish Mulleithid/Maol Leathan 'broad bare hill') is a townland in County Fermanagh, Northern Ireland. It is in the civil parish of Boho.

The Marble Arch Caves are a series of natural limestone caves located near the village of Florencecourt in County Fermanagh, Northern Ireland. The caves are named after the nearby Marble Arch, a natural limestone arch at the upstream end of Cladagh Glen under which the Cladagh River flows. The caves are formed from three rivers draining off the northern slopes of Cuilcagh mountain, which combine underground to form the Cladagh. On the surface, the river emerges from the largest karst resurgence in Ireland, and one of the largest in the United Kingdom. At 11.5 kilometres (7.1 mi) the Marble Arch Caves form the longest known cave system in Northern Ireland, and the karst is considered to be among the finest in the British Isles.

The Cuilcagh Lakelands Geopark formerly known as the Marble Arch Caves Global Geopark straddles the border between Northern Ireland and the Republic of Ireland. It is centred on the Marble Arch Caves and in 2001 it became one of the first geoparks to be designated in Europe. The Geopark features various sites which demonstrate the geological and wider natural heritage of the area, as well as the cultural heritage relating to 7,000–8,000 years of recorded human occupation since the last ice age. It is jointly managed by Fermanagh and Omagh District Council and Cavan County Council.

The Boho Caves (pronounced BOH, from Irish Botha, meaning 'huts') are a collection of caves centred on the village of Boho, County Fermanagh on the northern slopes of Belmore Mountain. They encompass the main Boho Cave and the smaller Waterfall Cave and Upper and Lower Ravine Caves. The Boho Cave system is the sixth-longest cave system in Northern Ireland, is designated an Area of Special Scientific Interest (ASSI #144) and is the only example of joint-controlled caves in Northern Ireland.

Carn or Carngreen is a townland situated in County Fermanagh, Northern Ireland. It is situated within the civil parish of Boho and Fermanagh and Omagh district.

Clogherbog is a townland in County Fermanagh, Northern Ireland. It is part of the civil parish of Boho, and contains the sub-townlands of Carrickrory, Lough Nacloyduff, Loughanquin, Loughnamanfin and Tullylaur. It is situated within Fermanagh and Omagh district. The area is notable for the discovered remnants of ancient civilisations, including an Iron Age wooden cauldron and the lettered cave at Lough Nacloyduff (the lake of the dark caverns), which contains primitive inscriptions. The origins of this cave have been speculated on since a visit by William Wakeman in 1850.Other features include the Mass rock which is inscribed with the date of 1777 and the Lake of the Fair Woman (Irish: Loch na mban fionn) which is the subject of an old tale.

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.
