Portstewart Strand is one of the easiest big beaches for an older dog
Portstewart Strand, just along the coast from Portrush and Portstewart town in County Londonderry, is a National Trust beach with a long run of sand backed by a high dune system towards the mouth of the River Bann. It's the obvious answer for anyone typing dog walks County Londonderry into their phone, and it genuinely earns the reputation — but the thing that makes it brilliant for a young, fit dog isn't automatically the thing that makes it kind to an old one.
The real selling point for a senior or arthritic dog is that you can drive onto the beach itself. That single fact changes everything for a dog who struggles with distance: there's no trek from a car park across dunes before the walk even starts. You park on firm sand, open the door, and your dog is standing on flat ground within a few steps. For a dog with hip or spine problems, that's worth more than any fancy route description.
Is the terrain actually manageable for stiff hips and sore joints?
The beach itself is about as flat as Northern Ireland gets, which is the main reason it suits an older dog better than most coastal walks in the north. The firm, damp sand near the tideline is easy going — level, no camber, nothing to twist a weak back leg on. The dry sand further up towards the dunes is a different matter: it's soft and uneven underfoot, and dogs with cruciate or hip issues often struggle more in soft sand than they do on a hard path, because every stride sinks slightly.
The dune system above the beach is where the gradient appears. There are boardwalks and timber steps in places to protect the fragile dune grass, and while they're not steep by hill-walking standards, a flight of wooden steps is a real obstacle for a dog with arthritic hindquarters. If your dog can't manage steps comfortably at home, don't plan on the dune paths here — stay down on the sand and treat the dunes as scenery rather than a route.
Where to park so your dog barely has to walk to reach the sand
The main entrance brings you straight onto the beach, and this is where most visitors park, especially in summer. It's convenient but it's also where the most car movement happens, which isn't ideal for a slow-moving senior dog who can't hop out of the way quickly if a car is manoeuvring nearby. There's usually a National Trust charge for parking on the beach unless you're a member — check current signage at the entrance rather than relying on anything printed online, as these things do change.
If your dog is nervous around traffic as well as stiff on their legs, it's worth driving a little further along the sand, away from the main access point, before stopping. The far end towards the Bann estuary is quieter and further from the car flow, and because you're still driving on firm sand to get there, your dog still doesn't have to walk any distance to be let out onto flat ground.
Are there benches, or anywhere to actually sit down?
Honestly, don't count on it. This isn't a park with benches dotted every so often — it's a working beach and dune system, and seating is limited to the area around the visitor centre and car park at the main entrance. Once you're down on the open sand or up among the dunes, there's nowhere formal to sit other than the sand itself, which isn't much comfort on a wet or windy day.
The practical workaround for an owner with an older dog is to treat the car as the rest point rather than hunting for a bench. Walk a short stretch, get back in, drive a bit further along if you both want more, or simply head home. It sounds unglamorous but it's the honest way to manage a walk here if your dog tires quickly or needs regular breaks.
What's the ground like in February and the rest of the winter?
The beach itself drains well because it's sand, so even after a wet few days the firm lower section near the tide is usually still walkable without turning into the kind of claggy mud you'd get on an inland path. The dunes are a different story — the sandy soil holds water in hollows after heavy rain, and the boardwalks can be slippery with algae or frost, which is exactly the surface you don't want under an arthritic dog's paws.
Wind is the bigger issue most days. This is an open, west-facing Atlantic beach with nothing to break the weather, and a stiff onshore wind driving rain sideways is completely normal for a Causeway Coast winter. An older dog with less muscle to keep them warm feels that cold far quicker than a younger one, so a coat and a shorter walk is often the kinder choice from November through to March, regardless of how the ground itself is coping.
The shorter routes worth knowing
For a dog who can't manage the full length of the strand, there's no need to feel you're missing out by keeping it brief. The simplest option is an out-and-back from wherever you've parked on the sand — walk for a few minutes in one direction, turn, and come back the same way, so you're never further from the car than your dog can comfortably manage to walk back.
If your dog can't cope with sand at all, even the firm section, Portstewart town itself has a paved promenade along the harbour that gives a flat, solid-underfoot alternative with sea air and a view, without any sand or steps involved. It's a sensible fallback on a day when the tide is in, the beach is busy with cars, or your dog is having a stiffer day than usual.
Lead rules, horses and other things to watch for
Portstewart Strand does have seasonal restrictions on dogs at certain times of year to protect ground-nesting birds in the dune system, and these are signposted at the entrance rather than fixed to a date you can rely on from one year to the next — always read the current notices before letting any dog off lead. Horses are occasionally exercised on the beach too, which can unsettle an older dog whose hearing or eyesight isn't what it was, so a lead is often the safer choice even outside any posted restriction.
The other real hazard is simply the cars on the beach. A young dog can dart clear in a second; an arthritic dog often can't turn or accelerate the way they used to, so keeping them on a lead near the driving area, and choosing a quieter stretch away from the main entrance where you can, removes most of the risk.
Getting there from Belfast and County Down
Portstewart sits on the Causeway Coast, reached from Belfast via the M2 and then onward through County Antrim towards the north coast — it's a proper coastal day out rather than a quick after-work walk, so it suits a weekend when you can take it slowly rather than squeezing it in. For a senior dog, that round trip is often enough excitement on its own, even before the walk itself.
If the full day is more than your older dog fancies, or you're heading up to the coast for a few days and need somewhere trustworthy for the rest of the household back home, that's exactly the sort of thing we help with day to day at Johnny's Doggy Hotel near Carryduff — whether that's a senior dog who'd rather have a quiet routine than a long drive, or company for a dog left behind while you're away.
