The Causeway Coast has one of the best runs of beaches anywhere in Ireland or Britain, and the wider north of Ireland adds a genuinely world-class one further south. This isn’t a generic “top 10” list - it’s a working guide to what actually makes each beach different, so you can pick the right one for what you want to do that day rather than driving to the first name you recognise.
Portstewart Strand
A two-mile Blue Flag beach owned by the National Trust since 1981, bounded by the River Bann estuary and backed by dune systems around 6,000 years old. It’s also a genuine Inclusive Beach, with equipment loan and Changing Places toilet facilities through the Mae Murray Foundation. Car access onto the sand costs £8 in summer (£3.50 in winter), free for National Trust members. See the full Portstewart Strand guide.
Benone Strand
Seven unbroken miles of golden sand from below Mussenden Temple to Magilligan Point - one of the longest stretches on this coast, and Northern Ireland’s first officially designated fully inclusive beach (2017). The adjoining Benone Tourist Complex offers camping, caravan pitches, and glamping if you want to base yourself here rather than just visit for the day. Full detail: Benone Strand guide.
Whiterocks Beach
Backed by dramatic white limestone cliffs (genuinely Cretaceous chalk, not the basalt seen at the Giant’s Causeway a few miles west), riddled with sea caves and arches including the Elephant Rock wishing arch. A frequent Blue Flag winner, popular with surfers and families alike. Dogs are welcome outside the 1 June-15 September restricted section. See the Whiterocks guide.
Portrush: West Strand and East Strand
Portrush has two distinct beaches worth telling apart. West Strand, right by the harbour and Barry’s Amusements, has the liveliest holiday atmosphere. East Strand, on the other side of Ramore Head, is longer, quieter, and backed by dunes and the Royal Portrush Golf Course rather than a promenade - better for a proper walk than an afternoon by the amusements. Guides: West Strand, East Strand.
Castlerock Beach
A shorter, 0.7-mile stretch between the cliffs of Downhill and the Lower Bann estuary, with Castlerock’s own railway station a short walk away - a genuinely easy beach to reach without a car. Castlerock Golf Club, one of Northern Ireland’s oldest links courses (founded 1901), sits right behind the dunes. Full guide: Castlerock Beach.
Downhill Beach
Sits directly beneath Mussenden Temple’s clifftop perch, with the Belfast-Derry railway line running through a tunnel at the base of the cliffs - watching a train emerge while looking up at the Temple is a genuinely popular, unusual sight. On-beach parking is free, with the same seasonal dog restrictions (1 June-15 September) as most of this coast. Guide: Downhill Beach.
Ballycastle Beach
A Blue Flag beach at the eastern end of the Causeway Coastal Route, with Pans Rocks - a historic sea-salt production site - at one end and Ballycastle Harbour and Marina at the other. RNLI lifeguards patrol through summer, and Ballycastle Golf Club (founded 1890) overlooks the beach from the clifftop. Guide: Ballycastle Beach.
Whitepark Bay
A broad, quiet, less commercial beach with genuinely old archaeological roots - Neolithic settlement evidence and a passage grave reportedly aligned to the midsummer solstice. Swimming isn’t recommended here because of dangerous rip currents; it’s a beach for walking and wildlife-watching (otters, porpoises, and dolphins are regularly seen offshore) rather than getting in the water. Full guide: Whitepark Bay.
Runkerry Beach (Bushfoot Strand)
A smaller, roughly 500-metre beach at Portballintrae, in easy reach of both the Giant’s Causeway and Dunluce Castle - a good, quieter stop if you’re already visiting either. Guide: Runkerry Beach and Bushfoot Strand.
Murlough Beach, County Down
Worth the detour south of the Causeway Coast proper: Murlough Beach, beneath the Mourne Mountains near Newcastle, is the centrepiece of Murlough National Nature Reserve - Ireland’s first nature reserve, established in 1967, protecting a 6,000-year-old dune system and internationally important wildlife habitat. It’s a genuinely different kind of beach experience, with the Mournes as a backdrop instead of basalt cliffs. Full guide: Murlough Beach.
