The Drive at a Glance

The Mournes are one of the best places in Ireland to bring a dog. River walks with deep pools for swimming. Ancient forests with trails through oak and cedar. Beaches that stretch for miles with barely another soul in sight. Open moorland where the only sound is wind and the padding of paws on heather. This weekend covers the highlights — two days of walking, splashing, sniffing, and exploring, with dog-friendly stops for breakfast, lunch, and dinner along the way. Your dog will sleep the whole way home. You probably will too.

Who It's For

Dog owners who want more than a car park loop. Active dogs, water-loving dogs, and dogs who think they're mountain goats.

What It Covers

3 forests, 2 beaches, 1 mountain trail, 1 reservoir, river walks, and a gravity hill that confuses humans (dogs unbothered)

What to Bring

Lead, poo bags, collapsible water bowl, towel for the car, treats, and a camera — your dog is about to have the best weekend of its life

I think dogs are the most amazing creatures; they give unconditional love. For me they are the role model for being alive.

Day 1

Rivers, Forest & Beach

Bloody Bridge river walk, Tollymore Forest, and Murlough Beach — your dog will be in and out of water all day.

Morning
Glen River path through Donard Forest, perfect for dog walks

Breakfast in Newcastle

45 min - 1 hour

Start the weekend at a dog-friendly spot on Newcastle's promenade. Niki's Kitchen Cafe has outdoor seating where dogs are welcome, or try The Great Eastern which allows well-behaved dogs inside. Get your Ulster fry, let the dog stretch its legs on the prom, and watch Slieve Donard catching the morning light. The beach beside the promenade is right there if your dog needs a pre-breakfast paddle.

9:30am5 min from Newcastle
Mountain river valley with granite boulders and clear pools

Bloody Bridge River Walk

1 - 1.5 hours

Five minutes south of Newcastle on the A2, pull into the Bloody Bridge car park. The name comes from a 1641 massacre, but today the river valley is one of the most peaceful walks in the Mournes — and one of the best for dogs. The path follows the Bloody Bridge River upstream into the mountains, with granite boulders and deep pools on both sides. Most dogs will be in the water within thirty seconds. The path is clear and well-worn — this was the start of the old smugglers' route over the mountains. Walk as far as you like and turn back. Twenty minutes in, the mountains close around you and the coast disappears behind.

Two rivers converging in Tollymore Forest Park

Tollymore Forest Park

1.5 - 2 hours

Back in the car and a ten-minute drive inland to Tollymore (*Tulach Mhór* — "the big hill"). This is the forest Game of Thrones used as the Haunted Forest, but forget the White Walkers — for dog walkers, this is paradise. Sixteen trails wind through ancient oaks, past stone bridges, along the Shimna River, and through an avenue of Himalayan cedars that feel like they belong in another century. The river crossings are the highlight — your dog will find every one of them. The 18th-century follies hidden throughout the forest are worth hunting for: gothic gates, a hermit's grotto, a clapper bridge. Most visitors walk the river trail and miss them entirely.

Lunch in Newcastle

1 hour

Head back into Newcastle for a dog-friendly lunch. If the weather's kind, grab a takeaway and eat on the beach — the dog won't complain.

2:30pm5 min from Newcastle
Murlough Nature Reserve, County Down — sand dunes and beach with the Mourne Mountains beyond

Murlough Beach & Dunes

1 - 1.5 hours

After lunch, drive north along the coast for five minutes to Murlough National Nature Reserve. This is one of Ireland's finest dune systems — 6,000 years old, stretching along the coast with Dundrum Bay on one side and the Mournes rising behind. The beach itself is spectacular: long, sandy, and usually quiet enough that your dog can run for as long as its legs will carry it. The dune boardwalk trail adds a gentler option if you want to save some energy. The reserve is managed by the National Trust, and the wardens are friendly. Check at the car park for any seasonal restrictions — ground-nesting birds use certain areas in spring and early summer, and those sections may require dogs on leads.

4:30pm5 min from Murlough
Sunset over a wide beach with mountain silhouettes

Newcastle Beach Sunset Walk

30 min - 1 hour

Return to Newcastle for the end of the afternoon. If the tide and light cooperate, walk the length of Newcastle strand with the dog. The beach stretches south towards Bloody Bridge, and with the Mournes behind you and the Irish Sea ahead, this is one of those walks where you stop thinking about time. Slieve Donard turns pink in the evening light. Your dog will be tired by now. So will you. That's the point.

Evening

Dinner in Newcastle

1.5 - 2 hours

After a full day of river walks, forest trails, and beach runs, you've earned a proper dinner. The Anchor Bar is a solid choice for pub grub in a traditional setting.

Day 2

Forest, Mountain & Moorland

Castlewellan lakeside, the climb to Cloughmore Stone, and the wild open space of Spelga Dam — a properly tired dog by teatime.

Morning15 min from Newcastle

Breakfast in Castlewellan

45 min

Start day two with a short drive inland to Castlewellan. The town is small and quiet — a good staging post before a morning in the forest park.

9:30am5 min from Castlewellan centre

Castlewellan Forest Park

1.5 - 2 hours

Walk straight from the town into Castlewellan Forest Park — one of the finest in Northern Ireland. The lakeside trail is a gentle 4km loop around the lake, flat and well-surfaced, with the Mournes reflected in the water on a still morning. For something more adventurous, take the longer forest trails up through the arboretum — some of the trees here are over 150 years old and came from as far as Japan and Chile. The Peace Maze (the world's largest permanent hedge maze when it was planted in 2001) sits in the grounds, though dogs aren't allowed inside. Drumena Cashel, a 1,500-year-old ringfort, is a short drive from the park if you want a historical detour.

12:00pm25 min from Castlewellan

Lunch in Rostrevor

1 hour

Drive south through Hilltown or via the coast road to Rostrevor (*Ros Treabhair*), the adventure village at the foot of Slieve Martin overlooking Carlingford Lough. The Kilbroney Bar & Restaurant has an outdoor area with lough views. Sit outside if the weather allows — the view across to the Cooley Mountains of County Louth is worth the drive alone.

Explore Rostrevor
1:30pm5 min to Kilbroney Park trailhead

Cloughmore Stone

1.5 hours (up and back)

The Cloughmore Stone (*An Chloch Mhór* — "the big stone") sits on the hillside above Rostrevor: a 40-tonne granite boulder that legend says the giant Fionn Mac Cumhaill hurled across Carlingford Lough from the Cooley Mountains in County Louth. The reality is almost as impressive — an ice-age erratic carried here by a glacier and deposited 15,000 years ago. The walk up from Kilbroney Park takes 30-40 minutes on a well-maintained forest trail. It's steep in places but manageable for any reasonably fit dog (and owner). The views from the top are extraordinary — Carlingford Lough, the Mournes, Slieve Gullion, and on a clear day, the Wicklow Mountains 100 miles south. Your dog won't care about the views. It will care about the squirrels.

Mountain reservoir surrounded by open moorland and distant peaks

Spelga Dam & the Gravity Hill

1 - 1.5 hours

The last adventure of the weekend. Drive up into the mountains from Hilltown to Spelga Dam, a reservoir sitting at over 300 metres in the heart of the Mournes. The landscape here is open moorland — heather, bog, and silence. This is the kind of place where you can see for miles and hear absolutely nothing. Let the dog off the lead (if no livestock in sight) and walk along the dam wall or out onto the surrounding hills. The water is shallow at the edges — perfect for a paddle. On the way back down towards Hilltown, you'll pass the famous gravity hill — a stretch of road where your car appears to roll uphill. Stop, put it in neutral, and let physics (or fairies) do their thing. The dog will be unimpressed, but you'll tell the story for years.

5:00pm

Spelga Views — Pull Over Here

10-15 min

On the drive back down from Spelga, pull into any of the laybys and take in the view. The Mourne peaks spread out in every direction. If the light is right — and in the late afternoon it often is — the mountains glow amber and the valleys fill with shadow. This is the quiet heart of the Mournes, away from the coast and the towns. A final moment of stillness before the drive home. Your dog has earned the car nap that's coming.

Evening15 min from Spelga to Rostrevor

Dinner in Rostrevor or Warrenpoint

1.5 - 2 hours

End the weekend with dinner before the drive home. If you head back through Rostrevor, try one of the local pubs for reliable pub grub in a friendly setting. In nearby Warrenpoint, The Whistledown on the seafront serves fish and chips with a view. The dog's weekend is done. Yours too. Two days of forests, rivers, beaches, and mountains — and a dog that'll sleep all the way home.

Insider Tips

Always carry poo bags — it sounds obvious, but the Mournes are grazing land and popular walking country. Leave no trace.

Forest Service parks (Tollymore, Castlewellan, Kilbroney) require dogs on leads at all times. Open mountain and beaches are generally off-lead, but watch for livestock.

Bring a collapsible water bowl. Your dog will drink from rivers and the sea, but having fresh water in the car saves arguments.

Spring and autumn are the sweet spot — fewer nesting-bird restrictions on beaches, cooler temperatures for walking, and the forests are at their most beautiful.

Murlough Beach has seasonal restrictions for ground-nesting birds (typically mid-April to mid-July in some areas). Check signage at the entrance and keep dogs on leads where indicated.

Keep a towel in the car. After Bloody Bridge river, Tollymore, Murlough beach, and Spelga Dam, your dog (and your car) will need it.

Dog-friendly dining is growing across the Mournes, but always ring ahead — policies change seasonally and with new management.

Spelga Dam and the mountain roads can be exposed. In winter, check conditions before driving up. The rest of the route is low-level and accessible year-round.
