Why Glenariff is worth the drive from Belfast
If you've typed something like dog walks Glens of Antrim into your phone, Glenariff Forest Park is almost certainly what came up, and it deserves the reputation. It's often called the Queen of the Glens, and the forest park sits in a deep, wooded gorge with the Glenariff River cutting through it, waterfalls dropping over mossy rock, and a viewpoint that opens out over the valley towards Red Bay and the sea. It's a different world from the Lagan towpath or Cave Hill, and dogs seem to know it the second the car door opens.
It's not a quick lunchtime walk from South or East Belfast, Carryduff or Newtownbreda – be honest with yourself about that before you set off. But for a weekend outing with a dog who needs proper miles of varied, interesting ground underfoot, it's one of the best dog walks near Belfast you can do, provided you plan the drive and the route properly.
Which gate should you actually use?
Glenariff Forest Park has two main points of entry, and which one suits you depends on which walk you want. The upper, main entrance is reached from the Glenariff side near Waterfoot, signposted off the road that climbs up through the glen. This is where the bigger car park is, along with picnic tables and, usually, toilets and some sort of visitor facility – though always check current signage on the day rather than relying on anything written here, as opening arrangements can change. This entrance suits the Scenic Trail and the viewpoint walk, and it's also where you'll find more coach parties and day-trippers in summer.
The lower entrance, off the Waterfall Road near Laragh Lodge, is the quieter option and drops you much closer to the start of the Waterfall Walkway. The car park here is smaller, so on a dry Saturday or during school holidays it can fill up faster than you'd expect – if you're relying on this gate, don't leave it too late in the morning. Neither entrance should be assumed to be free; check whatever current signage or payment arrangement is in place when you arrive, since this is the kind of detail that changes without much notice.
The main routes, honestly described
There are a handful of named trails that get combined in different ways depending on how long you've got and how fit your dog is.
The Waterfall Walkway is the one everyone comes for – a series of boardwalks, steps and riverside paths through the gorge, past the two named waterfalls, Ess-na-Larach and Ess-na-Crub. It's beautiful and well-built, but the boardwalks are narrower than photos suggest, and in places you're walking along a timber walkway with a real drop to one side and a dog on a lead that needs to stay close, not out exploring the edge.
The Scenic Trail, sometimes signed as the Viewpoint Trail, climbs up out of the gorge onto more open ground and brings you out at a viewpoint looking down the valley towards Red Bay. This section is longer, with more open farmland character to it, and it's where you're most likely to find sheep grazing nearby.
The Rivers Trail is the lower, gentler loop that follows the river on easier ground with less climbing and fewer steps – the one to choose for an older dog, a dog recovering from an injury, or a day when the weather's against you.
Fitter dogs and owners often link two or three of these into one longer outing, which can easily run to a few hours once you factor in stops for photos, picnics and letting an excited dog sniff every rock in the gorge.
Can you actually let your dog off lead here?
This is the question that matters most, and the honest answer is: it depends where you are, and you need to check on the day. Glenariff is a working forest park with grazing livestock in and around parts of it, and the usual rule across Forest Service sites applies – dogs must be kept under proper control, and leads are generally expected near livestock, in car parks and picnic areas, and on any section where signage says so.
On the Waterfall Walkway specifically, keep your dog on the lead regardless of how good their recall is. The boardwalks are narrow, often slick with spray and rain, and sit above a gorge with a genuine drop – it's not the place to test a dog's manners around a sudden squirrel or another dog coming the other way.
On the wider forest tracks away from the gorge and away from grazing fields, there's more room to breathe, and plenty of owners do let a reliable dog off lead on these open stretches. But livestock can be moved into different fields through the year, and lambing season in spring is a time when leads should go on without question, even on paths where you've previously walked off lead. Always read whatever signage is current at the gate you're using – it's updated for a reason.
What the ground is really like, month to month
In February and through most of the winter, expect the lower paths near the river to be waterlogged in places, the boardwalk timbers to be genuinely slippery, and a decent layer of wet leaf litter and mud at both car park approaches. The river itself often rises noticeably after heavy rain, which is common in the glens, and the waterfalls are at their most dramatic but the rock around them at its most treacherous – good boots matter, and a dog that pulls towards water needs a firm hand here.
In summer, the gorge keeps its own cool, shaded microclimate even when it's warm everywhere else, which makes the Waterfall Walkway a reasonable choice on a hot day when open ground elsewhere would be too much for a dog. The viewpoint trail, by contrast, is more exposed to sun and wind. Midges can be a nuisance on still summer evenings, particularly near the river, so evening visits are worth timing around that.
Across all seasons, assume the Glens will throw sudden rain at you even when Belfast looks dry – it's one of the most reliable features of the weather up here. A towel and a dry layer left in the car isn't optional kit, it's standard practice for anyone who walks this forest regularly.
Getting there from Belfast and County Down
From Belfast, Carryduff or Newtownbreda, there are two realistic approaches: the Antrim coast road, which takes you up through Larne, Carnlough and Waterfoot before you turn inland into the glen, or an inland route via Ballymena before dropping down into Glenariff. Both involve genuinely narrow, winding glen roads for the last stretch, and both can be slower than the map suggests, especially behind farm traffic or, in summer, tourist traffic moving slowly along the coast road to take in the views.
Treat this as a half-day or full-day outing rather than an evening stretch-the-legs walk. If you're coming from South Belfast, build in time for the drive and don't plan it as a squeeze-in-after-work trip – it rarely works out that way, and a rushed visit does nobody, least of all the dog, any favours.
If the Glens aren't on the cards this week
Not every week allows for a day trip to Antrim, and that's exactly when searches for dog boarding Belfast or doggy day care near me start to make sense. At Johnny's Doggy Hotel in Carryduff, close to Newtownbreda, we see plenty of dogs who've had a big day out in the Glens the weekend before and are happy to potter about closer to home in between – good boarding and day care isn't a replacement for Glenariff, it's what fills the gaps around it.
