Derrygonnelly ward lies in the rural southwest of County Fermanagh, centred around the village of the same name on the shores of Lower Lough Erne. The landscape is dominated by waterways, drumlin hills, and forested areas, with agriculture being a primary land use. The ward encompasses townlands like Church Hill and Tully, with a network of minor roads connecting scattered settlements and farms across its terrain.
The area is part of the Marble Arch Caves Global Geopark, with its underlying limestone responsible for notable karst features. This geological foundation supports a network of caves, sinking rivers, and natural arches in the nearby uplands. Social and economic activity is closely linked to the lough, with some focus on boating, angling, and related tourism alongside traditional farming practices.
