Why this one makes a proper day out, not just a walk
Most dog walks near Belfast are loops: round a park, back to the car, home for lunch. The Comber Greenway is different because it actually goes somewhere. It's a disused railway line turned shared path that runs from East Belfast, through Dundonald and Tullycarnet, out past Moneyreagh and into Comber itself, so you can genuinely treat it as a there-and-back day out rather than a quick lap.
That's the appeal for anyone searching for dog friendly East Belfast to Comber routes: it's long enough to properly tire a working breed, flat enough for an older dog or a dodgy hip, and it ends somewhere with a bakery. Whether you do the whole thing or just a stretch depends on your dog's fitness and your own patience for the walk back.
The route: where it starts, what's in between, where it ends
The Greenway's Belfast end is down near Dee Street, but very few dog walkers start there — most people pick it up further out, around Tillysburn or Orangefield, where it's quieter and easier to park. From there it runs past Knock, skirts the back of Dundonald near the Ulster Hospital and the Billy Neill Centre, then out past Tullycarnet Park, where there's a loch worth a detour if your dog fancies a look at the wildfowl (on a lead — more on that below).
Beyond Tullycarnet the character changes: fewer houses, more hedgerow and open farmland either side, through the Moneyreagh crossing and out towards Comber. The route finishes near the site of the old railway station, close to Comber town centre and the Enler River.
Doing the full length and back in one go is a serious outing — allow a proper chunk of the day, not a lunchtime stretch of the legs. Most locals treat it as modular: drive to a middle access point, walk a section, turn around.
- Belfast end: Dee Street/Tillysburn — more urban, busier with commuters
- Middle section: Dundonald, Billy Neill Centre, Tullycarnet Park
- Rural stretch: Moneyreagh crossing — open fields, fewer people
- Comber end: near the old station site, close to the town centre and the river
Where to park, and which end is actually quieter
Parking isn't a single answer because the Greenway has several access points, each with its own character. The Dundonald side near the Billy Neill Centre and the Ice Bowl tends to have the most space but also the most footfall, especially around school run and after-work hours, because it doubles as leisure centre traffic.
Tullycarnet, a bit further along, is generally calmer — residential streets lead onto the path and you're less likely to be queuing for a space. The Moneyreagh crossing has a handful of informal pull-ins rather than a proper car park, so it suits a mid-week visit more than a Saturday afternoon. At the Comber end, parking is informal around the old station area and the town itself, and you're close enough to walk straight into the centre afterwards.
Wherever you park, check the signage that's actually there on the day rather than relying on what worked last time — restrictions and resurfacing work do change, and farm gates along the rural stretch should never be blocked.
What the ground is actually like underfoot in February
This is the Greenway's real selling point for anyone walking dogs through a Northern Irish winter. Because it's built on an old railway bed, most of the surface is tarmac or compacted stone, so it doesn't collapse into the kind of ankle-deep mud you'd get on a forest trail after a week of rain.
That said, it isn't magic. The cutting sections — where the old railway runs below the level of the surrounding fields — hold standing water after heavy rain, and the hedgerows either side drip for hours once the rain itself has stopped, so a dog running the verges will come back wetter than you'd expect from a tarmac path. The exposed stretch out past Moneyreagh picks up a proper Belfast Hills wind too, so it's not a sheltered walk on a bad day.
The genuinely muddy bits are the side access points — farm lanes, field gates, informal entrances off side streets — rather than the path itself. If you're trying to keep a dog reasonably clean, it's the first and last few hundred yards at each end that catch people out, not the middle.
Lead on or lead off? Cyclists, runners and sheep
The Greenway is a shared path, and that matters more here than on most dog walks near Belfast. It's popular with commuter cyclists, especially the Belfast end during morning and evening rush, and with runners doing intervals along the straight, flat sections. A dog that's brilliant off lead in a quiet park can still surprise you when a bike comes round a blind bend at pace.
Further out towards Moneyreagh and Comber, the path runs alongside grazing fields, and livestock does turn up close to the fence line at times. Whatever your dog's usual off-lead reliability, it's worth keeping them on a lead or a long line through this stretch and checking the signage at each access point, since restrictions can vary section to section and do get updated.
Wet-dog logistics: towels, boot liners and no rinse point
There's no official dog wash or hose point anywhere along the route that we'd rely on, so plan as if there isn't one. A decent microfibre towel in the car, a boot liner or an old duvet cover over the seats, and a bottle of water for muddy paws will save you a lot of grief, particularly if you're doing the Comber end and then want to sit somewhere nice afterwards.
If you've parked at one end and walked to the other and back, remember your dog is picking up two lots of hedgerow drip and verge mud rather than one — by the time you're back at the car after a there-and-back walk, they'll be wetter than the walk length alone suggests. Worth bearing in mind before you decide the whole route is a one-way trip rather than out-and-back.
Where to go afterwards
Comber itself is the obvious reward at the far end — there are bakeries and coffee shops around the town centre with outdoor seating, which suits a damp dog far better than trying to squeeze inside. Policies on dogs do vary from place to place and can change, so it's worth checking with the specific café rather than assuming.
If you fancy extending the day rather than heading straight back, Castle Espie Wetland Centre is a short drive further on and is worth a look, though it's a wetland nature reserve with its own rules around dogs that vary by area and season — check their current dog policy before you go rather than turning up and hoping.
If you're coming from Carryduff, Newtownbreda or anywhere around south Belfast and would rather walk the whole Greenway at your own pace without rushing back for the dog, that's exactly the kind of day Johnny's Doggy Hotel's day care is built for — drop the dog off, do the walk properly, and collect a happy, already-exercised dog on your way home.
