Castlerock Beach

General Beach Description

Castlerock is a 1km (0.7 mile) long stretch of beach between the sea cliffs of Downhill to the west and the Lower River Bann estuary known as the Barmouth to the east. Castlerock Beach frequently attains the Blue Flag Award, most recently in 2024. Castlerock beach backs on to the tranquil resort of Castlerock. The dunes to the east of the entrance are home to Castlerock Golf Club.

Visitors can access the beach via the dunes by means of 4 new boardwalks. Cars are permitted on the eastern portion of the beach all year round, although access may be difficult due to accumulation of soft wind-blown sand (please heed signage at entrance).

Walkers and anglers can walk along the concrete pier of the Barmouth but should exercise extreme caution at all times (inadvisable during high winds and breaking swell).
