Amazing sea cliff climbing on impeccable granite. There is a wide variety of routes from multi-pitch overhangs to sea stacks. Apart from the most obvious, stars have yet to be given to the routes but all are of very high quality! Plenty scope for new routing too.
Good topo here.
Dan, one of the islanders, is happy to take people out on his boat for a small charge. Transfer is 10 mins but always call Dan Gallagher, the boatman's on 0035386601389. Camping is a great option with the ideal site very close to the harbour in grassy areas sheltered by stone walls. All crags are within a 20 minute walk. At certain times there is B&B available on the island for those who do not like to camp. Alternatively, kayak across.
