You don't need a flight for a world-class beach summer. Northern Ireland packs seven-mile strands, sheltered lough shallows and Blue Flag sand into one small country — and every beach on this list is free to visit.
The spread — golden strands on the north coast, a white-sand cove in the Glens, four beaches under the Mourne Mountains on the Down coast, and easy family bays at Bangor and Millisle. Wherever you live, serious sand is closer than you think.
Cost — all ten are free to visit; parking is the only cost where there is one. At Portstewart the charge is for driving onto the sand itself (card only, National Trust members free). Every entry links to our full guide with the detail.
Swimming — flags first.RNLI lifeguards patrol the flagged beaches in July and August — Benone and Cranfield run daily daytime patrols — and several beaches on this list are unpatrolled, so swim between the flags where they fly and mind the tide everywhere.
Dogs — summer rules. Most of these beaches restrict dogs in the bathing season, roughly June to mid-September (April to September at Newcastle). Check the signs on the day before letting them off.
Food — Harry's Shack serves proper food on the sand at Portstewart, Newcastle's prom lines up cafés, chip shops and ice cream, and Cushendun has a tea room in the village. Everywhere else, a picnic is the play.
When — long summer evenings are the secret weapon, and a quick tide check makes every one of these better: low tide means rock pools at Whiterocks and Millisle and huge open sand everywhere else. Pack water and a hat and make a day of it.

Portstewart Strand
Portstewart · Free to walk · Charge to drive on (NT members free)
Two miles of golden National Trust sand where you drive on and park right beside your spot — the car boot becomes base camp for the whole day. Often called one of the best beaches on the island: clean water, rolling surf, dune trails through the Bann Estuary nature reserve behind, and Harry's Shack serving proper food on the sand. Free to walk on; the charge is for driving on (card only). RNLI lifeguards patrol in summer — swim between the flags.
Half a day or moreHarry's Shack · seasonal toiletsStick to the firm sand — soft sand near the dunes bogs cars down
Seven miles of Blue Flag sand under the Binevenagh cliffs — and another one you can drive onto, claiming a firm golden patch beside the car. No rocks, no shingle, just proper buckets-and-spades territory with kitesurfers and land yachts out beyond. It's Northern Ireland's first fully inclusive beach, with beach-access equipment to pre-book through the Mae Murray Foundation, and the Benone Tourist Complex next door opens its outdoor heated splash pools daily in July and August. RNLI lifeguards patrol July and August, 10am–6pm.
2–4 hours, easily a dayFree · free parking on the sandBeach is zoned · dogs restricted 1 June – 15 Sept — follow the signs
A Blue Flag beach beneath white limestone cliffs carved into caves, arches and sea stacks — and one of the north coast's best surf spots. Little ones get wide bucket-and-spade sand, older ones get rolling waves, and a seasonal outlet hires boards and wetsuits right on site. At low tide the rock pools and caves open up, and the clifftop path east gives big sea views toward Dunluce Castle. Free, with a free car park above the beach. Lifeguards July and August — swim between the flags.

Dundrum, Co. Down · Free to walk · NT parking charge
Northern Ireland's first nature reserve — boardwalk trails winding through a wild dune system to a long open beach on Dundrum Bay, with the Mourne Mountains sweeping down to the sea behind. Summer brings butterflies and wildflowers to the dunes, and seals sometimes haul out across the bay. Free to walk; the only charge is the National Trust car park (members free, card only). No café and no lifeguard, so pack a picnic, mind the tide when you paddle, and keep dogs on leads.
2–3 hours, longer on a good dayNT parking charge · members freeFragile dunes — keep to the boardwalks and marked paths
Newcastle, Co. Down · Free · Pay-and-display parking in town
A long sweep of sand and a proper seafront promenade, with Slieve Donard rising straight off the end of the beach. Build the castle, paddle the shallows, then work along the prom for ice cream, chip shops and amusements — and on summer days the Rock Pool, a 1930s open-air seawater lido, makes a brilliant add-on (own admission). Public toilets sit by the seafront, and Donard Park is a stroll away when legs want grass. RNLI lifeguards patrol in the main summer season — check the flags on the day.
2–4 hours, easily a dayProm cafés, chip shops & ice creamDogs out of the marked amenity area 1 April – 30 Sept
Tyrella, Co. Down · Free · Parking charge in season
A Blue Flag beach with two kilometres of flat golden sand, grassy dunes behind and the full Mourne skyline across Dundrum Bay — one of the best mountain views from any beach in Down. It's big and open enough to share with horse riders and kayakers, and there's a new inclusive-beach set-up with accessible equipment. Free to walk on; parking is charged at weekends from Easter to September and daily in July and August. Lifeguards patrol in the main season — swim between the flags, and mind the tide outside it.
2–3 hours, easily a dayFree beach · parking charge in seasonDogs out of the bathing area 1 June – 15 Sept, 10am–6pm
A gently sloping sandy beach at the very mouth of Carlingford Lough, where the water runs warm, shallow and sheltered — said to be one of the best family swimming beaches in County Down, with the Cooley Mountains standing right across the water. Toilets, showers, a grassy picnic area and a children's play park sit behind the sand, all free, with a free car park and disabled bays. RNLI lifeguards patrol daily 11am–6pm through July and August, then September weekends. It's a lough mouth, so keep paddlers close.

Cushendun, the Glens · Free · Free village car parks
A small, sheltered sandy beach where the Glendun river meets the sea, wrapped in the green hills of the Glens — with the red Cushendun Caves a short walk along the shore. The National Trust village behind it was designed in Cornish style by Clough Williams-Ellis, and a tea room and Mary McBride's pub are two minutes from the sand. Free, with two free village car parks — they're small, so land early on a sunny day. No lifeguard: it's a calm-day paddling beach, and the caves cut off at high tide.

Bangor, Co. Down · Free · Seafront & on-street parking
Bangor's long, easy sweep of sand and promenade — a beach walk, a paddle and a proper play, with sailing dinghies and paddleboards out on the bay. Play areas at both ends keep little ones going for hours, public toilets bookend the beach, and Ballyholme village is a short stroll away when the ice-cream call comes. Free, no ticket — there's a seafront car park (open 5am–11pm) plus on-street parking, and both fill fast on a hot day. No lifeguard, so mind the tide and keep an eye on swimmers.
2–3 hours, a full afternoonFree · no ticket, just turn upDogs on a lead on the beach 1 June – 31 Aug, 11am–8pm
Millisle, Ards Peninsula · Free · Large shorefront car park
The Ards Peninsula's ready-made family seaside day: sand, a promenade, a pirate-ship play park and a purpose-built seawater lagoon with a children's paddling pool that refills fresh on every tide. Rock pools line the northern stretch, there are toilets and picnic tables at the beach park, and shops and cafés are a short walk into the village. Free, with a large shorefront car park — and Ballycopeland Windmill is a five-minute drive for an easy add-on. No lifeguard, so keep a close eye on children in the lagoon and the sea.

The drive-on double: morning on Benone with the splash pools (open daily July and August), then along the coast to Portstewart Strand for the afternoon and food at Harry's Shack.
The Mournes day: boardwalks and dunes at Murlough in the morning, then round to Newcastle's prom for chips, ice cream and a summer dip in the Rock Pool.
The little-legs day: the lagoon and pirate ship at Millisle in the morning, rock pools on the northern stretch after lunch, and Ballycopeland Windmill on the drive home.
