Clonea is a broad sandy beach on the sheltered east side of the Ballinacourty headland, a few kilometres east of Dungarvan. It's the town's beach, and the Waterford Greenway runs right past it, so you can walk or cycle there from town in under an hour.
There's a camping and caravan site behind the beach. The castle that once stood here washed away in winter storms in 1990.
