On a 90m-high cliff, this 23m-tall working lighthouse, complete with a Fresnel lens, rises up above Loop Head. Guided tours (included in admission) take you up the tower and onto the balcony – in fine weather you can see as far as the Blasket Islands and Connemara. There's been a lighthouse here since 1670; the present structure dates from 1854. It was converted to electricity in 1871 and automated in 1991.
It's possible to stay at the neighbouring former lighthouse keeper's cottage.
