Set off from Killybegs for a 1¾‑hour guided cruise to the base of Europe’s highest accessible sea cliffs. Expect close-up views of caves, waterfalls and lighthouses, plus seasonal sightings of dolphins and basking sharks.
More ways to explore the area's outdoor wonders
A low swell rocks the small passenger boat as it slips away from Killybegs harbour and the coastline opens up — sheared rock, white surf, and a wind that seems to push the horizon back. Within an hour the cliffs of Slieve League rise like a coastal wall, 1,972 feet (601 m) of dark rock plunging straight into the Atlantic. The captain eases the bow close and the engine’s hum gives way to birds and the drip of waterfalls daring the sea.
