We did this tour on the advice of trip advisor. Couldn't fault it! Our tour guide Eddie was a wealth of knowledge (an ex-lighthouse keeper at Ballycotton). His passion for the island and lighthouse was inspiring and wonderful to listen to. The island itself was beautiful with 360degree views. Quick boat ride over and bit of a walk up the hill to the top but well worth it. We had an overcast day but it didn't ruin the trip at all. Trip lasting about 90min. Only €20 and worth every cent. Highly recommend!
