Cross to Abbey Island at low tide
The ruin stands on Abbey Island, joined to the sand by silt so you can walk over dry-shod — but only when the tide is out. At high tide, and on new-moon and full-moon tides, the crossing is submerged.




A roofless sixth-century ruin perched on a beach-linked "island", Derrynane Abbey overlooks one of Ireland's loveliest strands — and you can only walk out to it when the tide is out.

Only three roofless buildings survive, the highlight being a shale-and-limestone Romanesque church with a low door and sea-facing arched windows still in remarkable condition.
The graveyard is still in use and coffins are shouldered across the sand; look for Celtic crosses and the graves of Mary O'Connell, wife of Daniel O'Connell, and the poet Tomás Rua Ó Súilleabháin.
Below the abbey this Blue Flag beach is good for a swim or picnic; swim only in the marked areas and mind the strong currents of 'Danger Beach'. Derrynane Sea Sports hires kayaks, sailing boats and windsurfing gear.
A short walk inland, the ancestral home of Daniel O'Connell is now a museum of his life and relics, set in over 120 hectares of coastal parkland.
