The Erriff River is one of the most prolific salmon fisheries in Ireland.
The falls were a filming location for the 1990 movie 'The Field'.
The surrounding valley is a classic U-shaped glacial formation.
The name Aasleagh derives from the Irish 'Eas Liath', meaning 'grey waterfall'.
Aasleagh Falls is a series of cascading waterfalls located on the Erriff River near the head of Killary Harbour in County Mayo, Ireland. The falls are situated at the border between County Mayo and County Galway. The water drops over a series of limestone ledges, creating a tiered effect that spans the width of the river. It is a known site for salmon leaping, particularly during the autumn migration period. The area is a designated Special Area of Conservation. The river's flow is influenced by heavy rainfall in the surrounding mountains, which can significantly alter the appearance of the falls. Visitors access the riverbank via a small roadside parking area. The site serves as a scenic waypoint along the Wild Atlantic Way driving route.
The viewing area adjacent to the small roadside car park offers a direct perspective of the full width of the cascades.
Wear waterproof footwear as the riverbanks can be muddy and slippery.
Visit after a period of heavy rain to witness the falls at their most dramatic volume.
Exercise caution if walking near the water's edge, as the current is strong.
Do not attempt to swim or wade in the river, as the undertow and currents are dangerous.
Practice 'Leave No Trace' principles and keep dogs on a leash to protect local wildlife.
