Dunluce Castle — North Antrim Clifftop Ruin

Dunluce Castle is perched on a sheer basalt promontory above the North Antrim coast, connected to the mainland by a narrow bridge. The ruin dates to the 13th century and was the seat of the MacDonnell clan — part of the gatehouse literally fell into the sea during a storm in 1639. It sits right on the A2 Causeway Coastal Route between Portrush and Ballycastle, making it a natural stop when you’re linking the Giant’s Causeway area with the Glens of Antrim. Managed by the Northern Ireland Environment Agency; there’s a small admission fee to enter the castle grounds, but the clifftop views are visible from the roadside pullout for free.

Parking is directly off the A2 in a dedicated lot. Road access is fully paved and manageable for any rig. Busy in peak summer — arrive before 9am or after 5pm to avoid coachloads. The coastal path west toward Portrush is worth a short stretch on foot.
