Gaelforce Great Fjord Swim

About the Event

Dive into one of the most celebrated events on the Gaelforce Great Swim Trilogy calendar: the Great Fjord Swim, an open water spectacle set against the stunning backdrop of Killary Fjord. This unique swim offers swimmers a chance to immerse themselves in crystal-clear Atlantic waters while being surrounded by Connemara's dramatic mountain peaks.
Suitable for all levels and backgrounds, participants can choose from four distinct courses ranging from a manageable 750m swim—where you launch directly into the heart of Ireland’s only fjord—from a boat—to an exhilarating new 8km marathon distance designed to challenge even the most seasoned open water athletes. Each course offers its own set of challenges and rewards, ensuring that swimmers are treated to awe-inspiring views at every turn.
The Great Fjord Swim promises not just a physical test but also a profound connection with nature. With meticulous safety measures in place for all participants, this event ensures an unforgettable experience from start to finish. Whether you're a beginner or an experienced swimmer looking to push your limits, the Great Fjord Swim is an unmissable opportunity to embrace the beauty and tranquility of Ireland's west coast.
Join fellow swimmers at Killary Fjord for this unique blend of athleticism and natural splendor—a true bucket-list adventure that celebrates both personal achievement and the breathtaking landscape of Connemara.
