Completed in 1909 to help warn ships off the rocks, Mizen Head signal station is perched high above crashing waves and contorted sea cliffs on a small island connected to the mainland by a spectacular 45m-high bridge. From the visitors centre (you have to pay the admission fee to get to the island), it's a 10-minute walk via 99 steps to reach the station, which houses exhibits on the station's history and on marine wildlife – keep a weather eye open for whales and dolphins.
Back at the visitors centre there are displays about local ecology and history, and on the building of the Fastnet lighthouse. There's also a modest cafe.
