South Stack Lighthouse (Ynys Lawd)
Trinity House’s 1809 lighthouse on its own islet off Holy Island, reached down (and back up) 400+ cliff steps and a bridge. Open weekends 10.30am–4.30pm from 31 October.
South Stack Lighthouse was built by Trinity House in 1809 on Ynys Lawd, a small island off the western tip of Holy Island. The only way to the lighthouse is down 400+ steps on the steep mainland cliff, across a bridge to the island, and back up the same steps afterwards. When tours run, they can include climbing the tower.
The lighthouse sits below the RSPB South Stack Cliffs reserve, which is a separate attraction with its own listing.
