Overview
Lough Erne is not a single body of water but a connected network of the Upper (southern) and Lower (northern) lakes, linked by the River Erne as it flows north toward the Atlantic. Covering more than 300 square miles, it ranks as the second-largest lake system in Northern Ireland and the fourth largest on the island. The waters are threaded with over 150 islands, sheltered bays and winding inlets, creating a landscape that has shaped local mythology, supported centuries of fishing and sailing, and drawn visitors seeking quiet natural beauty.
The lake forms the core of the Fermanagh Lakelands UNESCO Global Geopark, recognised for its distinctive limestone karst topography, rolling drumlins and rich wildlife. Enniskillen, a historic island town that straddles the narrow channel between the two lakes, serves as the main gateway. From here, visitors can hop on a boat, explore ancient monastic sites, or simply follow the shoreline paths where the water meets woodland.
History & Legend
The name Lough Erne likely traces back to the ancient Érainn tribe or to Érann, a figure in Irish mythology sometimes linked to Ériu, the namesake of Ireland. Local lore offers three traditional origin stories: a drowned lady-in-waiting of Queen Méabh, a magical spring that burst its banks, and a legendary battle that split the earth to form the basin. These tales reflect how deeply the landscape is woven into Irish storytelling.
- Early settlement – Ptolemy’s second-century map notes the Menapii in this region, a people who later evolved into the Fir Manach, giving County Fermanagh its name. The seventh-century king Mongán mac Fiachnai features heavily in local lake legends, with several islands bearing names tied to his court.
- Monastic heritage – The lake’s islands became centres of early Irish Christianity. The Annals of Ulster were compiled on Belle Isle, while Devenish Island grew into one of the most important monastic settlements, founded in the sixth century by St Molaise.
- World War II – RAF Castle Archdale on the Lower Lough served as a vital flying-boat base during the Battle of the Atlantic. Pilots used the “Donegal Corridor” to fly west across neutral Ireland, cutting hours off their journey to convoy routes.
- Modern recognition – The area has gained international attention for its natural and cultural assets, including hosting the 2012 G8 summit at Lough Erne Resort and consistently ranking highly for sustainable tourism and outdoor recreation.
Island Highlights
The islands are the crown jewels of the lakelands, each offering a different blend of history, nature and quiet reflection. All are accessible only by water, with regular passenger boats and hire options running from late spring through autumn.
- Devenish Island – Dominated by a nearly 30-metre-high round tower dating to the 12th century, the island also holds St Molaise’s Church, St Mary’s Abbey and a carved high cross. Entry to the grounds is free, and the visitor centre typically opens Thursday to Sunday in peak summer, extending to weekends in September.
- Boa Island – Connected to the mainland by a road bridge, Boa Island is famous for the Caldragh cemetery, which holds the enigmatic Janus stone (double-faced) and the older ‘Lustyman’ figure. The island also features early Christian crosses and a quiet coastal walking trail.
- White Island – Reached by ferry from Castle Archdale, this small island contains the remnants of a 12th-century church whose walls incorporate carved stone figures reportedly rescued from a Viking raid.
- Crom Estate – A four-star nature conservation area on the Upper Lough, known for ancient woodland, red squirrels, pine martens and a network of marked walking trails. Weekday visits rarely require booking, but weekends fill quickly.
Watersports & Outdoor Activities
The sheltered waters and consistent breezes make Lough Erne a natural playground for paddlers, sailors and anglers.
- Sailing & regattas – Lough Erne Yacht Club at Gublusk Bay stages Ireland’s oldest sailing race, running since 1820. The Broadmeadow stretch near Enniskillen also hosts the World Waterski Championships each summer.
- Kayaking, canoeing & paddle-boarding – Local operators provide equipment hire and guided trips ranging from gentle island-hopping routes to longer coastal expeditions.
- Fishing – The 80-mile River Erne system is renowned for brown trout, rainbow trout and pike. Anglers must purchase a licence through the Department for Infrastructure Rivers before fishing.
- Cycling – The Kingfisher Trail’s Southern Loop (227 km) and Northern Loop (155 km) weave through the lakelands, crossing the water via passenger ferries.
- Walking & cave exploration – Forest-loop walks circle the lake, including routes at Castle Archdale and Ely Lodge. For a change of scenery, the Cuilcagh Boardwalk (“Stairway to Heaven”) and the Marble Arch Caves are short drives away, with combo passes often available that pair cave tours with a lake cruise.
Lakeside Stays & Dining
The lakelands cater to a range of budgets and travel styles. The Lough Erne Resort sits on a 600-acre peninsula and offers two championship golf courses, a spa, an infinity pool and several restaurants, including the award-winning Catalina. The resort frequently runs packages that bundle accommodation with guided visits to nearby attractions like Florence Court, Enniskillen Castle or the Marble Arch Caves.
For self-catering and family stays, options like Rossharbour Resort, Killyhevlin Chalets and Share Discovery Village provide chalets and lodges set directly on the shoreline. Many lakeside pubs and cafés in Enniskillen, Belcoo and Belleek serve fresh local produce and seasonal lake fish.

Plan your island visits for mid-morning to avoid the earliest ferry queues, and allow extra time for the Devenish round tower climb if you want clear photos without crowds. The lake’s rhythm is slow by design, so leaving room for an unplanned stop at a waterside café or a quiet forest loop will make the most of the lakelands.
