The South Stack lighthouse is built on Ynys Lawd, a small rocky island just off the edge of Holy Island, which itself is an island just barely separate from the main part of Anglesey. To reach it you need to descend a switchback stairway running down the cliff face, over 400 steps down (and 400 back up). At the bottom a bridge carries the visitor over a chasm to the island. Once there, you can explore the tiny island, view the exhibition about the history of the lighthouse, and climb more steps in a guided tour to the top of the 28m tall lighthouse tower.
