Killary Harbour is Ireland’s only true fjord and extends 16km (10 miles) in from the Atlantic to its head at Aasleagh, below Aasleagh falls. It forms the border between Galway and Mayo and boasts some of the most spectacular scenery in the west of Ireland. Killary Harbour is also extremely deep, over 45m at its centre. To the north lies Mweelrea, the highest mountain in Connacht and County Mayo. To the south are the Twelve Bens and the Maumturk Mountains of Connemara. Majestic views greet the visitor from all directions.
