A boardwalk lifts you off the sand and winds you in through the dunes — 6,000 years of them, marram grass leaning in the wind, the biggest dune-heath system in Ireland. In summer the paths run through wildflowers and clouds of butterflies; the reserve is home to more than 600 kinds of butterfly and moth, including the rare marsh fritillary, which the National Trust says is of European importance.
Then the dunes open and there's the beach — a long, generous sweep of sand with the Mourne Mountains standing right across Dundrum Bay, Slieve Donard highest of the lot. It's made for a proper beach walk in any weather, a paddle when it's warm, a picnic in the dunes, kites and running-around and staring out to sea. Look to the water and you might catch seals hauled out on the sand; the National Trust counts anywhere from 50 to 130 common and grey seals resting along this coast.
Bring what you need and you've got the whole day — the reserve is quiet, wild and free to wander, the kind of place you leave with sand on your feet and your head cleared out. Just keep to the boardwalks and marked paths to protect the dunes and the ground-nesting birds, and you're set.
Plan your visit
Can I just turn up? Yes — it's free to walk.
The reserve is open and free to wander any day of the year in daylight — no booking, no ticket. The only cost is parking: there's a charge at the car park for non-members (National Trust members park free — just scan your card at the machine). The machines are cashless, card only, with a pay-by-app option too. It's pay-and-display all year, and the rate is higher in the summer months — around £5 a day in the main season and less off-peak, so check the board on the day. Facilities here are limited, so come stocked up.

Good to know
Everything before you go
Cost
Free to walk. Parking is charged for non-members — pay-and-display all year, cashless (card only), with a pay-by-app option. Rates are higher in summer (around £5 a day in the main season, less off-peak). National Trust members park free — scan your card at the machine. Confirm the current rate on the day.
Opening
The reserve is open all year in daylight hours; you can walk it any time. The main car park can be seasonal — confirm on the day, especially in winter.
What you'll see
A 6,000-year-old sand-dune system, boardwalk and heath trails, a long sandy beach, big Mourne Mountains views across Dundrum Bay, butterflies and wildflowers in summer, and seals sometimes hauled out offshore.
Toilets
Seasonal — weekends only in April and May (10am–4pm), then daily June to August (10am–5pm), including accessible toilets. None outside those times, so plan ahead.
Dogs
Dogs welcome but must be kept on leads at all times, including on the trails — this protects ground-nesting birds and grazing livestock. Some grazing and nesting areas are out of bounds to dogs; watch for the signs, especially in bird-nesting season.
Accessibility
Honest steer: this is soft sand and sandy boardwalk, so it's not ideal for wheels. The boardwalk is wheelchair-friendly but not all-terrain, and there's no wheelchair access onto the beach itself. Accessible parking and toilets are available.
Prams
Soft sand and boardwalk are hard going for a light stroller. An all-terrain buggy will manage the boardwalk; a sling or back-carrier is easiest for little ones.
Food
Nothing on site — no shop or café. Bring a picnic, or head into nearby Newcastle or Dundrum for a bite after.
How long
Allow two to three hours for a good wander through the dunes and along the beach — easily longer if the sun's out and the kids get into the sand.
Questions
Before you go
Is it free?
The reserve itself is free to walk, any day of the year. The only charge is parking, and only for non-members — National Trust members park free by scanning their card. The machines are card-only, so no need for cash, but confirm the current rate on the board.
Do I need to book?
No — just turn up and walk. There's no ticket or booking for the reserve.
Can I bring the dog?
Yes, dogs are welcome, but they must stay on a lead at all times, including on the trails — it protects the ground-nesting birds and grazing animals. Some nesting and grazing areas are closed to dogs, so keep an eye on the signs.
Is it good for prams and wheelchairs?
Being honest: it's soft sand and sandy boardwalk, so it's tough for wheels. The boardwalk is wheelchair-friendly but not all-terrain, and there's no wheelchair access onto the beach. There's accessible parking and toilets. An all-terrain buggy or a carrier works best with little ones.
Are there toilets and a café?
Toilets are seasonal — weekends in April and May, then daily June to August. There's no shop or café on site, so bring a picnic and water; Newcastle and Dundrum are close for food after.
Will we see the seals?
Sometimes — the National Trust says 50 to 130 common and grey seals use this coast to rest and feed, so scan the sand and the water. No promises on the day, but keep your eyes out.
Getting there
Murlough National Nature Reserve, Keel Point, Dundrum, Newcastle BT33 0NQ — just off the A2 near Dundrum, between Dundrum and Newcastle in County Down, with the pay-and-display car park on site.
Murlough is where it all began. When it was declared in 1967 it became Northern Ireland's — and Ireland's — first nature reserve, and it has been in the care of the National Trust ever since. The dunes it protects are ancient: a sand-dune system reckoned to have been forming for around 6,000 years, now the finest and most extensive dune heath in Ireland.
That's why the boardwalks matter. The dunes are fragile and alive — home to the marsh fritillary and hundreds of other butterflies and moths, wildflowers, and birds that nest on the ground. Keep to the marked paths and the whole place stays wild for the next family that comes. Then it hands you the reward: a long open beach, the Mournes standing across the water, and the sea rolling in.
