Why Slieve Gullion is worth the drive from Belfast
If you've typed dog walks Newry, County Armagh into your phone, Slieve Gullion Forest Park above Killeavy is almost certainly what came up, and it deserves the attention. It sits inside the Ring of Gullion, the ring of hills around south Armagh, and it's one of the few places within reach of Belfast and County Down where a dog walk stops being a lap of the local park and starts being an actual outing: forest, open hill, a lake at the summit, and views that change completely depending on which direction you're facing.
It's not a quick pop-out walk. You're committing to a drive past Newry and into proper countryside, so it works best as a half-day plan rather than something squeezed in before work. That's the trade-off, and for most dogs — especially the ones that get bored of the same twenty minutes around a housing estate green — it's worth it.
The route itself: forest, courtyard loop, and the summit
The Forest Drive is the thing most people have heard of, but it's a scenic driving route with viewpoints and pull-ins rather than a walking trail, so don't plan on walking dogs along it — traffic uses it too. The actual walking happens from the courtyard area, where waymarked trails run out through mixed conifer and broadleaf woodland before opening onto rougher hill ground.
The main event is the summit walk up to the twin cairns and Calliagh Berra's House, the passage tomb near the top, past what's often described as the highest lake in Ireland. It's a proper climb — not technical, but steep in stretches, with loose stone and exposed rock near the summit. On a clear day you get the Cooley Mountains, the rest of the Ring of Gullion spread out below, and on a really good day the Mournes and beyond. On a wet, low-cloud day you get none of that and a much harder walk down, so check what the weather's doing before you commit to the top.
For dogs that just want a good sniff and a stretch of legs rather than a hill climb, the lower forest trails around the courtyard are enough on their own and considerably kinder on paws and joints.
- Lower forest loop: mostly flat, good surface, shaded
- Summit trail: steep, stony near the top, genuinely tiring
- Views: worth the climb on a clear day, pointless in low cloud
Getting there from Belfast and County Down
The drive is straightforward: down through Newry and out towards Camlough and Killeavy, following the signs for Slieve Gullion Forest Park. Newry itself can slow you down at commuter times, particularly around the town centre and the approach roads, so if you can avoid rush hour, do — the roads open up nicely once you're clear of the town and heading into the hills.
It's a longer trip than most of the walks people do straight out of Belfast, Carryduff or Newtownbreda, so treat it as a day trip rather than an after-work walk. Bring the usual car kit — water, lead, poo bags, something to sit the dog on — because once you're out past Newry there's not much in the way of shops until you're back in town.
Where to park at the main gate
The main entrance and courtyard car park off the Killeavy Road is where most visitors go, and it's generally the easiest place to leave the car with a dog, close to the start of the lower trails and the toilets. It fills up on dry weekends and school holidays, so an early start or a midweek visit gets you a quieter car park and a quieter trail.
The Forest Drive has its own gate further round, which can have restricted opening hours or seasonal closures — check the signage on the day rather than assuming it's open, especially outside the summer months.
What the ground is actually like in winter
This is south Armagh hill ground, and it behaves like it. In February, the lower forest tracks are fine underfoot but the open moorland below the summit gets genuinely waterlogged — think peaty, sucking ground rather than a bit of puddle-hopping. After a hard frost the summit path itself can carry ice on the exposed rock, which is worth knowing if you've got an older dog with dodgy hips or a dog that's not steady on slippery ground.
Summer brings its own problems: bracken on the lower slopes holds ticks, and the open hill has no shade at all once you're above the treeline, so a hot, still day up there is harder on a dog than it looks from the car park.
The wet-dog logistics: what to actually bring
Don't assume there's a tap or hose waiting for you back at the car — bring your own water for rinsing paws and bellies, along with old towels and something to line the boot. A dog that's been up and down the summit trail on a damp day will come back plastered from the chest down, not just the paws, so a full-body towel-down before it gets in the car saves you a filthy interior on the drive home.
A change of footwear for yourself is no bad idea either — the peaty ground has a way of getting into boots that trainers never quite recover from. If the courtyard has a café or facilities open on the day you visit, treat that as a bonus rather than something to plan around; what's open can vary, so it's worth having your own flask and dry layer regardless.
Where to go afterwards: dog friendly Newry, County Armagh
Once you're back down and the worst of the mud is off, Newry town itself is the obvious next stop. The Newry Canal towpath gives a flat, easy cool-down walk if the dog's still got energy in the tank after the hill, and it's a much gentler surface than anything on Slieve Gullion. Several cafés and pubs in and around the town have outdoor seating that tolerates a well-behaved dog, though policies vary from place to place, so it's worth a quick check or a phone call before you sit down with a wet dog under the table.
For readers further up towards Belfast, Carryduff or Newtownbreda, a trip like this is exactly the kind of day where it helps to have things sorted at the other end — whether that's someone keeping an eye on a second dog at home, or a plan in place for the days you can't bring the dog with you at all. That's really the whole reason places like Johnny's Doggy Hotel exist: so a big day out doesn't have to mean leaving a dog behind, and a day when it does mean that, the dog's somewhere it actually wants to be.
