A gently-sloping sandy beach at the very mouth of Carlingford Lough, where the water runs warm, shallow and sheltered — one of the best family swimming and paddling beaches in County Down, with the Cooley Mountains standing right across the water.
What you'll do — swim and paddle in safe, shallow, sheltered water, build castles on the soft sand, wander the promenade, let the kids loose on the play area, and take in the big Carlingford Lough and Cooley Mountains views.
How long & who for — an easy half-day, two to four hours, longer on a warm one. Genuinely brilliant for families with young children — the shallow water is the whole draw.
Cost & parking — completely free. There's a free car park right by the beach, with disabled bays.
Bring the lot — buckets and spades, towels, swim gear, a windbreak and a picnic. There are toilets and showers, and a hat and plenty of water for a sunny day.
Facilities & food — toilets, showers, a promenade, grassy picnic area and a children's play park. Seasonal café/kiosk nearby and the town of Kilkeel a couple of miles up the road.
Lifeguards in the summer season only. RNLI lifeguards patrol daily 11am–6pm through July and August, then weekends in September. Outside those times there's no cover, so mind the tide and swim between the flags when they're up.
This is the mouth of a lough — the tide moves. The channel here has currents and the water sweeps in and out with the tide, so keep little ones close, watch the incoming tide, and don't let paddlers drift out.
Plan your visit
Can I just turn up? Yes — it's free, with a free car park
Cranfield is open and free all year — no booking, no ticket, and there's a free car park right beside the beach with disabled bays and ramped access down to the sand. The big draw is the water: it faces south into the mouth of Carlingford Lough, so it's warm, shallow and sheltered, which is exactly why families love it for swimming and paddling. It holds a Blue Flag award for its water quality and facilities. The beach is backed by a promenade, a grassy picnic area and a children's play park, and it's an accessible beach — through a partnership with the Mae Murray Foundation you can borrow all-terrain beach wheelchairs and mobility equipment (register ahead). Toilets are seasonal, so come stocked up for the day.

Come prepared:
Lifeguards are on duty in the summer season only, and this is the mouth of a lough with real tides and currents — swim between the flags when lifeguards are up, keep little ones close, and always watch the incoming tide. Toilets are seasonal, so bring water and everything for the beach. Confirm lifeguard dates and any dog restrictions before you set off.

Good to know
Everything before you go
Cost
Free. There's a free car park beside the beach, with disabled bays and ramped access to the sand.
Opening
Open all year in daylight hours — turn up any time. Facilities such as toilets and the seasonal kiosk run in the warmer months; confirm on the day, especially off-season.
The water
South-facing, gently sloping, warm, shallow and sheltered at the mouth of Carlingford Lough — one of County Down's best beaches for family swimming and paddling. It's a Blue Flag beach for water quality and facilities.
Lifeguards
RNLI lifeguards patrol in the summer season — daily 11am–6pm through July and August, then weekends only in September. There's no lifeguard cover outside those times, so take extra care. When lifeguards are on, swim between the red-and-yellow flags.
Tides & safety
This is the entrance to a lough, so there are tidal currents and the water moves in and out with the tide. Keep young children close, watch the incoming tide, and don't let paddlers or inflatables drift out into the channel.
Facilities
Toilets and showers (seasonal), a promenade, a grassy picnic area and a children's play park. A seasonal café/kiosk operates nearby.
Accessible beach
Cranfield is an inclusive beach — through a partnership with the Mae Murray Foundation, all-terrain beach wheelchairs and mobility equipment can be borrowed free of charge (register ahead of your visit). There's disabled parking and ramped access to the sand.
Dogs
Dog access is restricted at the main bathing beach in the summer season — check the signs on the day and keep dogs under close control. There's open shore either side; watch for the current notices.
Food
A seasonal kiosk nearby; otherwise bring a picnic. Kilkeel town is a couple of miles up the road for a fuller bite after.
How long
Allow two to four hours for a good beach day — easily a full day if the sun's out and the kids get into the water and the play park.
Questions
Before you go
Is it free?
Yes — the beach is free and so is the car park beside it, which has disabled bays and ramped access down to the sand. No ticket, no booking.
Is it safe for children to swim?
It's one of the best family beaches in County Down for exactly this — the water is warm, shallow, sheltered and gently sloping. That said, it's the mouth of a lough with real tides and currents, and lifeguards are only on in the summer season. Keep little ones close, swim between the flags when lifeguards are up, and always watch the incoming tide.
Are there lifeguards?
RNLI lifeguards patrol in the summer season — daily 11am–6pm through July and August, then weekends only during September. Outside those times there's no cover, so take extra care. Confirm the dates before you travel.
Can I bring the dog?
Dog access is restricted at the main bathing beach over the summer season — check the signs on the day and keep dogs under close control. There's open shore either side.
Are there toilets and food?
There are seasonal toilets and showers, a promenade, a grassy picnic area and a children's play park, plus a seasonal kiosk nearby. Bring a picnic and water to be safe, with Kilkeel town close for food after.
Is it good for prams and wheelchairs?
Yes — Cranfield is an inclusive beach. There's ramped access to the sand and disabled parking, and through the Mae Murray Foundation you can borrow all-terrain beach wheelchairs and mobility equipment free (register ahead).
Getting there
Cranfield Beach, Kilkeel, County Down BT34 4LN — about two miles south-west of Kilkeel at the mouth of Carlingford Lough, with a free car park right beside the beach.
Cranfield sits right where Carlingford Lough opens out to the Irish Sea, just south-west of the fishing town of Kilkeel. That position is the whole secret: the beach faces south into the sheltered mouth of the lough, so the sea rolls in warm and shallow over gently-sloping sand — the kind of water where children can splash for hours and parents can actually relax. It's long been one of County Down's favourite family beaches for exactly that reason, and it wears a Blue Flag for its water and its facilities.
Look across the water and you're looking at another country: the Cooley Mountains of County Louth rise straight up on the far shore, with the Haulbowline Lighthouse marking the channel out to sea. Behind you there's a promenade, a play park and the caravan parks that fill up every summer. It's a proper old-fashioned bucket-and-spade day — just remember the tide moves at the mouth of a lough, so keep the little ones close and enjoy the water while the lifeguards are on.
