About the Event

Experience the enchanting waters of Lough Derg near Portumna with the Gaelforce Great Lake Swim, part two of the prestigious Gaelforce Great Swim Trilogy. This unique freshwater swim invites participants to explore the mystical islands and ancient ruins that dot the lake's surface against a backdrop of Ireland’s stunning countryside.
The event offers three distinct distances catering to all levels: beginners can start with an introductory loop designed for building confidence in open water, while more experienced swimmers have options ranging from a challenging middle distance to the full Ironman swim. Swimmers are encouraged to choose a course that matches their skill level and comfort zone. Whether you prefer the buoyancy of a wetsuit or the raw sensation of swimming “skins,” this event accommodates both preferences.
Safety is paramount at Gaelforce Great Lake Swim, with comprehensive measures in place to ensure every participant enjoys a secure and thrilling experience. Immerse yourself in the serene beauty of Lough Derg on July 10, 2027, for an unforgettable aquatic adventure.

About County Donegal

Learn more about the host city, County Donegal.

County Donegal is in Northwest Ireland and Lakelands Region and is the northernmost county in Ireland, stretching further north than any part of Northern Ireland. It's a large county but mostly hill and forest, with a population in 2022 of 167,000. Historically part of Ulster, Donegal was one of its three counties that joined the Republic of Ireland, while the other six are in Northern Ireland. So it's referred to as part of "the south" in spite of being so far north.
