Kilbroney Park Is Worth the Trip, But Not Every Path Suits an Old Dog
Kilbroney Park sits at the foot of Slieve Martin on the edge of Rostrevor, with Carlingford Lough stretched out below and the Mournes rising behind it. It's one of the best-loved dog walks near Belfast for a reason — the mix of woodland, river and sea views is hard to beat, and it's a proper day out rather than a quick lap of a local park.
The catch, if you're walking an older dog or one with arthritis, is that most of what Kilbroney is famous for involves climbing. The path up to the Cloughmore Stone is steep, rocky in places, and genuinely testing even for a fit adult. None of that needs to put you off the park altogether. There's a gentler, flatter side to Kilbroney that most visitors drive straight past on their way to the viewpoint, and that's the bit worth knowing about.
Where to Park, and Which Entrance Is Quieter
The main car park is at the park entrance off the Shore Road as you come into Rostrevor from the Kilkeel direction, close to the playground and the walled garden. This is the easiest spot for an older dog, because it's a short, flat walk from the car to the riverside path rather than a scramble over a verge or a kerb.
There's also parking further up, near the start of the forest drive, which is handy if you only want to walk the upper paths — but it means more uneven ground underfoot before you've even started, and on a wet day the surface up there can be loose gravel and puddles rather than anything smooth. For a dog with sore joints, the lower entrance is the better bet almost every time.
Weekends and bank holidays bring a lot of day-trippers, especially once the weather turns decent, and the main car park can fill up by early afternoon. A weekday morning, or an off-season visit, gives you a much calmer start — no queue of cars, no excitable children running past the boot as you're trying to get an arthritic dog settled on the ground.
The Flat Loop That Actually Suits Stiff Hips: Fairy Glen
The path that follows the Kilbroney River through what locals call the Fairy Glen is the one to head for. It runs along the valley floor rather than up the hillside, weaving under mature trees with the river running alongside for most of it. The gradient here is gentle — nothing like the climb further up — which makes it by far the most forgiving stretch of the park for a dog that's slow to get going or stiff after lying down.
The surface is a mix of packed earth, some older tarmac sections nearer the entrance, and the odd stretch of tree root where the path narrows. None of it is difficult for a dog walking comfortably, but it's worth knowing the roots are there if your dog is a bit unsteady behind, so you can slow down rather than let them pick their own pace over them.
There are a couple of footbridges crossing the river as the path loops back on itself, and these have a bit of camber and the odd loose board depending on when they were last checked. Fine for most dogs, but one to approach steadily rather than at a trot if your dog's back end isn't what it used to be.
- Flattest ground: the stretch closest to the main car park and walled garden.
- Watch for: tree roots on the narrower sections and a slight camber on the footbridges.
- Best time: weekday mornings or an off-season visit, when the path isn't busy with children on bikes.
Where the Benches Are, and When to Turn Back Early
There are benches along the lower paths near the walled garden and at a few points along the riverside walk — enough that you can plan a route with a sit-down roughly every few minutes rather than committing to a full loop with nowhere to rest. If your dog tends to stiffen up after standing still for a photo or a chat with another dog walker, a bench to sit on while they get going again is more useful than it sounds.
The honest advice for an arthritic dog is to treat the full riverside loop as the ceiling, not the target. Walk as far as the first or second bench, see how your dog is moving, and if they're starting to shorten their stride or lag behind you on the way back, that's your answer — don't push on to finish the circuit just because you can see the end of it. Kilbroney isn't going anywhere; there's always a next visit.
Leave the Cloughmore Stone for Another Dog
The walk up to the Cloughmore Stone is the thing most people come to Kilbroney for, and it's a genuinely good climb if you and your dog are up for it — but it's a proper hill walk, not a park stroll. The path is steep in sections, uneven underfoot, and there's a real drop in temperature and wind exposure once you're up near the stone itself, even on a day that felt mild at the car park.
For a dog with arthritis, sore elbows, or any kind of hip or spine issue, this one is best left for a younger or fitter dog, or for a human-only walk while your own dog waits in the car with the window down and water to hand, or simply stays home. There's no shame in driving to Rostrevor, doing the flat valley loop, and never going near the hill at all — plenty of locals do exactly that with their older dogs.
What the Ground Is Actually Like in February
Like most of County Down, Rostrevor gets its share of driving rain and low cloud through the winter, and the Fairy Glen path holds water in the low-lying sections near the river. Expect mud rather than ice as the main hazard most winters — this part of the coast rarely gets a hard freeze that lasts — but after a spell of heavy rain the packed-earth sections can turn greasy enough that a dog with weak back legs can slip on an incline that wouldn't normally trouble them.
The river itself runs higher and faster after rain, and the stepping-stone crossings some walkers use to shortcut between paths become genuinely risky rather than a bit of fun. If your dog isn't steady on their feet, stick to the proper bridges and keep them on the lead near the bank — there are no barriers along most of the river, and a dog that slips in cold February water is a bad end to a nice walk.
A Flatter Fallback: Rostrevor's Shore Walk
If you arrive at Kilbroney and the park feels busier or wetter than you fancy, Rostrevor village itself is dog friendly and sits right on Carlingford Lough, with a promenade along the shore that's as flat as walking gets. It's a different kind of walk — more sea air and passing dogs than woodland — but for a dog that's had a rough week with their joints, a level surface, a bench every so often, and the lough view can be a better outing than any hill, however small.
It also makes a sensible plan B for a day when the forecast has changed by the time you've left Belfast: forest paths hold water for days after rain, while the shore walk drains and dries much faster.
If You're Planning Ahead
A trip to Rostrevor is a good outing even for dogs that are slowing down, as long as you pick the valley path over the hill and don't mind cutting the walk short. If you're further afield in Belfast or County Down and looking for dog friendly days out, Rostrevor earns its reputation. And if a day like this is part of a longer trip south, or you need somewhere trustworthy for your dog while you're away, it's worth sorting dog boarding in Belfast or doggy day care near you in advance rather than leaving it to the week before — places that know older and arthritic dogs, like ours at Johnny's Doggy Hotel in Carryduff, tend to get booked up around the better weather.
