Lough Erne in County Fermanagh, Northern Ireland, is a two-part lake system connected by the River Erne flowing through Enniskillen, running south to north from Upper Lough Erne to Lower Lough Erne. The total canoe trail covers approximately 42 miles. Access to the water is free and no licence is required to paddle.

Upper Lough Erne is characterized by a maze of bays, narrow channels of slow-moving water, and innumerable islands and peninsulas, making it well suited to beginners and families. Lower Lough Erne, north of the Rossigh access point, is known locally as the "broad lough" and can become very rough in strong winds, making it more appropriate for experienced paddlers. Duross Bay and Glenross Bay on Lower Lough Erne contain significant submerged rocks and should be avoided entirely. Navigation markers — red and white spades — indicate shallow water at various points around the lough.

The River Erne section through Enniskillen carries a small current flowing northward. It is generally possible to paddle upstream for most of the year, though paddlers should keep to the left bank when travelling downstream to use the channel through the lock.

Because the system allows loop routes, many paddlers can start and finish from the same access point without requiring a vehicle shuttle, though local hire providers offer shuttle services. Key access points include Rossigh, which has a pontoon and a wild campsite, and Castle Archdale Marina on the eastern shore of Lower Lough Erne, identifiable by a large white cairn at its entrance. Castle Archdale Country Park has a campsite and amenities. Trory also offers access and a wild campsite.

Notable landmarks along the route include Devenish Island, where an 81-foot 12th-century round tower — founded as a monastic settlement by Saint Molaise in the 6th century — is visible from the water well before arrival. White Island holds the ruins of a 13th-century church and seven carved stone figures. Enniskillen Castle and the Crom Estate are also accessible from the trail.

kingfishers, otters, and herons can be found along the shores. The quiet shorelines and some islands are suitable for wild camping. Wind direction is the primary factor affecting travel conditions on the lough sections, as the current is negligible there, and checking the forecast before launching is strongly advised.
