The Trip at a Glance
The Mourne Mountains get a quarter of a million visitors a year. Most of them walk the same trails, park in the same car parks, and take the same photographs. This itinerary is for the people who want to see what the crowds miss. An ice house buried in a hillside. A stone older than the pyramids, standing in a field where nobody will bother you. A stretch of mountain road that defies the laws of physics. And a forest full of 300-year-old architectural jokes that most Game of Thrones fans walk straight past. None of these places are signposted from the main roads. None of them appear in the standard guidebooks. All of them are real, visitable, and free. You just need to know where to look.
Who It's For
Curious explorers, history lovers, anyone who's already done the Slieve Donard summit and wants to dig deeper.
What It Covers
1 ice house, 1 Neolithic dolmen, 1 gravity hill, a forest of follies, and a river that inspired Narnia
What to Bring
Walking boots, a torch, camera, waterproof jacket, and a willingness to leave the beaten track
“The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.”
Marcel Proust
The Route
Newcastle — Hilltown — Spelga — Tollymore
9 stops. Take your time — the drive itself is the destination.

Breakfast in Newcastle
45 min - 1 hourStart the day in Newcastle with a proper breakfast before heading into the hills. You'll need the fuel — today is about walking, climbing, and peering into corners most people never find. Grab a table somewhere on the Main Street with a view of Slieve Donard, and take your time. The hidden Mournes aren't going anywhere. They've been hiding for centuries.

The Ice House — Glen River Walk
1 - 1.5 hours (round trip)From the Donard car park in Newcastle, follow the Glen River upstream. The path climbs gently through oak woodland with the river tumbling beside you. After about twenty minutes, leave the main track and take the path up the hillside to the left. Built into the slope, half-buried in earth and moss, sits a stone dome — an ice house constructed in the early 1800s for the Annesley estate. In winter, servants cut blocks of ice from the river pools and packed them inside this chamber, insulated by the hillside. The ice lasted through summer, supplying the kitchens of Donard Lodge below. The structure is remarkably intact: a corbelled stone dome, maybe three metres high, with a low entrance you can crouch through. Inside, the air drops several degrees even on a warm day. Most walkers heading for Slieve Donard march straight past it without knowing it's there.

Goward Dolmen — Finn's Finger
30-45 minDrive inland through Bryansford and up towards Hilltown. A few miles before the village, a small brown sign points you down a farm lane. At the end of it, in a field with views across to the Mournes, stands Goward Dolmen — known locally as *Cloch an Bhile*, or Finn's Finger. A massive capstone, estimated at 50 tonnes, balanced on upright stones for roughly five thousand years. Nobody knows exactly how Neolithic people managed this. The engineering is extraordinary. The setting is extraordinary too — just you, the stones, and the mountains. There's no visitor centre, no ticket booth, no interpretive panels. Just a gate, a field, and a mystery older than the pyramids. The farmer doesn't mind visitors, but close the gate behind you.

Lunch in Hilltown
45 min - 1 hourHilltown (*Cromghlinn* — "crooked glen") sits at the crossroads of old smuggling routes through the Mournes. In the eighteenth century, this tiny village had eight pubs on a single street — all of them linked to the contraband trade. The pubs have thinned out since then, but the village still has places to eat. Try The Hilltown Courtyard or Ernie's Bar for a hearty lunch — soup, sandwiches, and the kind of portions that fuel an afternoon of exploring. You're deep in the Mournes now. This is farming country, and the food reflects it.
Explore Hilltown
Spelga Dam & The Magic Hill
30-45 minFrom Hilltown, take the Spelga Road south into the mountains. The road climbs steeply, winding between heather-covered hills until you reach Spelga Dam — a reservoir built in the 1950s to supply Banbridge and Newry, with panoramic views across the High Mournes. But the real curiosity is a stretch of road just past the dam. Pull over, put your car in neutral, and take your foot off the brake. The car rolls — uphill. Or at least it appears to. This is a gravity hill, an optical illusion created by the surrounding landscape that tricks your brain into perceiving a downhill slope as an uphill one. The locals have a different explanation, naturally. They'll tell you it's the fairies. Either way, it's genuinely unsettling. Try it with a bottle of water on the dashboard — the water appears to flow the wrong way too. Spelga itself is worth lingering. On a clear day you can see Slieve Donard, Slieve Commedagh, Slieve Binnian, and the entire western Mournes laid out before you. The silence up here is total.

15-20 minBefore descending from Spelga, stop at the viewpoints along the road heading east. The Mourne Wall is visible as a thin line drawn across the summits — 22 miles of dry-stone wall built by hand over 18 years, crossing 15 mountain peaks. From up here you understand the sheer audacity of the project. Men carried every stone. The wall crosses no roads. There are no gates. It simply runs from summit to summit in an unbroken line across the highest ground in Northern Ireland. On clear days, the Isle of Man is visible to the east and the Wicklow Mountains to the south. This stretch of mountain road between Spelga and Tollymore is one of the most beautiful drives in the Mournes, and most visitors heading straight to the forest never take it.

Tollymore Forest Park — The Follies Trail
1.5 - 2 hoursDescend from Spelga through the mountain pass and into Tollymore Forest Park. Game of Thrones fans know Tollymore as the Haunted Forest — the very first scenes filmed for the show were shot here. But the forest holds secrets far older than Westeros. In the 1750s and 1760s, the Roden family who owned the estate commissioned a series of architectural follies throughout the grounds: a Gothic gate, a hermit's grotto, an ornamental bridge, a barn disguised as a church, a clapper bridge built to look ancient. They're scattered through the forest like a treasure hunt, and most visitors — even regular walkers — pass them without a second glance. Follow the river walk and keep your eyes open. The Horn Bridge spans the Shimna River with a pair of Gothic arches. The Hermitage is a stone grotto built into the riverbank. The Barbican Gate looks like it belongs to a medieval castle. None of them served any practical purpose. They were built purely for delight — which is the best reason to build anything.
Read the full storyThe Shimna River Walk
30-45 minIf you have energy left after the follies trail, follow the Shimna River upstream on the longer forest loop. The river is crystal clear — you can count individual stones on the riverbed. Salmon run up here in autumn. In summer, pools of amber water sit perfectly still between mossy boulders. This is the section of forest that C.S. Lewis loved. He visited Tollymore as a boy, and scholars believe the ancient trees and stone bridges inspired parts of Narnia — the Lantern Waste, the Great River, the deep woods where Mr. Tumnus lived. Walk slowly. Listen to the water. You've spent the whole day finding things other people miss. This river is one more.
The Narnia connectionDinner in Newcastle
1.5-2 hoursReturn to Newcastle for dinner. After a day of hidden things, you've earned a proper meal. Try Niki's Kitchen Cafe for hearty comfort food, or walk along the promenade to The Anchor Bar for something more relaxed with views of the beach. The conversation over dinner will be easy — you'll be full of stories. An ice house nobody told you about. A stone older than the pyramids. A hill that defies gravity. A forest hiding 300 years of architectural jokes. The Mournes have been keeping these secrets for centuries. Now you're in on them.
More restaurantsInsider Tips
Wear proper walking boots. The Ice House trail is rough ground off the main path, and Goward Dolmen is in a field that can be muddy after rain.
Bring a torch for the Ice House interior. It's dark inside the dome and a phone light won't do justice to the corbelled stonework.
The Spelga Road from Hilltown is narrow and winding with steep drops. Take it slowly, especially in mist. The views are worth the concentration.
Goward Dolmen has no car park — just a layby and a farm lane. The brown heritage sign is easy to miss. Search "Goward Dolmen" in Google Maps for the exact location.
Tollymore closes its gates at dusk (times vary seasonally). Check the posted times when you arrive and work backwards to make sure you're not locked in.
This itinerary works brilliantly in autumn when the Tollymore trees turn gold and the shorter days give Spelga a moody, dramatic atmosphere.
