At the King Sitric restaurant on the East Pier, a 2½-km (1½-mile) cliff walk begins, leading to the white Baily Lighthouse, built in 1814. In some places, the cliff path narrows and drops close to the water, but the views out over the Irish Sea are terrific. Some of the best views in the whole Dublin area await from the parking lot above the lighthouse, looking out over the entire bay as far south as Dun Laoghaire, Bray, and the north Wicklow coast. You can also see quite a bit of Dublin.
