Marble Arch Caves Global Geopark

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.

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.

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.

Shannon Cave is an active stream passage cave which straddles the border of County Fermanagh, Northern Ireland and County Cavan in the Republic of Ireland. At 130 metres (430 ft) vertical depth, it stands joint sixth with Poulnagree in County Clare in the deepest caves on the island of Ireland. The cave is recorded at 5.4 kilometres (3.4 mi) in length (making it the sixth-longest on the island of Ireland), but exploration is ongoing and further passage is expected to be found.

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.
