About Castlerock

Castlerock is a Blue Flag beach on the Causeway Coast at the mouth of the River Bann in County Londonderry, a long sandy strand backed by dunes and the village. Lifeguarded in summer, it is a popular family and surf beach, with the dramatic Mussenden Temple and Downhill Demesne perched on the cliffs nearby. A fine north-coast beach with reliable Atlantic waves.
