County Down keeps its coast in three separate pieces, and the useful thing about that is how little the three have in common. At the southern end, wide sand sits under the Mourne Mountains in Dundrum Bay. North of that the Ards Peninsula runs flat and agricultural for thirty miles, its shoreline a mix of sand, shingle and low rock with farmland rather than promenade behind it. Round the top, Belfast Lough turns everything sheltered, wooded and close to town. One short county, three very different days out.
What the twelve beaches below have in common is a rule, not a look. None of them carries a seasonal dog ban, which is not the norm on this island's better known stretches of coast, so a walk here is planned around the tide and not the calendar. Eleven of them sit in County Down itself. The last, Greencastle, is over on the Antrim shore of Belfast Lough and is included because it is a short drive from the Down beaches at the top of this list. Two of the twelve do apply lead rules on their promenades, and both are flagged below.
Tyrella Beach
Two kilometres of golden sand inside Dundrum Bay, with mature dunes rising behind it and a designated conservation area covering the lot. The Mournes rise to the south and give the whole bay a backdrop that belongs to a much more remote place than this one actually is, because Tyrella is tucked off the busier coastal routes and feels enclosed rather than exposed. Low water opens out a very large amount of firm ground.
That low tide sand is the reason to come with a dog. It runs wide and level, easy on older joints, and the marram behind it holds enough scent to occupy a nose for an hour. Two things to weigh. The car park is paid, and there is nothing else at all on site, no toilets and no cafe, so bring water. Horse riding uses the beach from time to time, which matters if your dog reacts badly to them.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand
- Tides: Wide sands at low tide, Mourne Mountains behind
- Parking: Paid car park at Tyrella Beach
- Facilities: None on site, occasional horse riding on the sand
- Nearest dog beach: Ballykinler Beach, 2.1 miles
- Best for: Long level walking at low water under the Mournes
Ballykinler Beach, Downpatrick
Ballykinler carries on where Tyrella leaves off, two miles round the same south facing shore and backed by the same dune system. It is the wider and emptier of the pair, running for miles when conditions allow, with the Mournes again filling the view inland. The public way in is the Tyrella section, reached by a toll road that charges for the privilege.
Here is the caveat that decides whether you go at all. Much of Ballykinler is a military training area, and beach access varies with whatever the army is doing that week, so check before setting out rather than after driving down. When it is open it is among the finest beach settings in the county and one of the quietest, exposed to southerly swell and short on facilities, with Newcastle the nearest town for anything you have forgotten.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand and dunes
- Tides: South facing, wide sands, exposed to southerly swells
- Restrictions: Access may be restricted during military training, check before visiting
- Parking: Toll road from Tyrella, charge applies
- Facilities: Very limited, Newcastle town for full amenities
- Nearest dog beach: Tyrella Beach, 2.1 miles
- Best for: Space and emptiness, on a day the range is quiet
Ballywalter Beach
South of the village the sand runs for roughly three kilometres with fields directly behind it and almost no building at all. This is the Ards Peninsula doing what it does best: a working agricultural edge meeting the Irish Sea, with the Isle of Man and the Cumbrian coast somewhere out on a clear horizon. Rock pools surface among the sand once the water drops away.
No seasonal restriction applies here, which the peninsula manages more often than the resort coast does, and the rural backing keeps numbers low even in August. The sand is flat and forgiving for dogs of any age, and the pools hold seaweed and crabs for the ones who investigate rather than sprint. The limitation is arrival and amenity. Parking is roadside in Ballywalter only, and nothing stands at the beach itself, though the village has cafes a short walk back.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand
- Tides: Good at most tide states, rock pools exposed at low water
- Parking: Roadside parking in Ballywalter, no car park
- Facilities: None at the beach, cafes in the village
- Nearest dog beach: Millisle Lagoon, 3.2 miles
- Best for: A quiet rural sand walk with rock pools to work through
Millisle Lagoon
A small sandy beach on the Ards coast that forms a natural seawater lagoon, with an old outdoor tidal pool still in place beside it. The effect is dated in the best sense, a piece of mid century seaside that the rest of the coast has grown out of, and the whole site is compact and sheltered where the open peninsula shore is neither.
Still water is the point. The lagoon stays calm when the coast outside is not, which suits a dog that wants to paddle but backs off from surf, and the enclosed shape of the site takes some of the pressure off an unreliable recall. It will not give you a long walk though. This is a twenty minute stop rather than an afternoon, better suited to an older dog pottering than a young one that needs running, and the caravan park next door means summer weekends are not quiet.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand
- Tides: Sheltered lagoon, calmer than the exposed Ards coast
- Parking: Car park at Millisle Beach Park
- Facilities: Toilets, seasonal facilities, caravan park alongside
- Nearest dog beach: Millisle Beach, 2.1 miles
- Best for: Nervous paddlers and short, contained visits
Millisle Beach, Newtownards
The village beach proper, two miles along from the lagoon and facing north east into the Irish Sea. Sand and shingle in roughly equal measure, used by local families and entirely unbothered about impressing anybody. Above the village stands Ballycopeland Windmill, an eighteenth century tower mill restored and open to visitors, which is a better reason to combine the trip than most beaches can offer.
Nothing restricts dogs at any point in the year. The mixed surface is the thing to think about though, because shingle underfoot is harder work than the clean sand at Ballywalter and not every dog takes to it. Amenities in the village are thin, so Donaghadee up the coast is the usual answer for lunch. What Millisle gives you instead is a beach that is never full and never far from the car.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand and shingle
- Tides: North east facing Irish Sea beach
- Parking: Roadside parking at Millisle beach
- Facilities: Limited village amenities, Ballycopeland Windmill above the village
- Nearest dog beach: Millisle Lagoon, 2.1 miles
- Best for: An easy local beach with somewhere to go afterwards
Donaghadee Beach
Donaghadee is the nearest point in Ireland to Scotland, twenty one miles across the water from Portpatrick, and the town has the lighthouse and the harbour to show for it. The beach is sandy with shingle along its upper edge and popular with local families. Grace Neill's Bar, which claims 1611 and the title of oldest pub in Ireland, is a two minute walk from the sand.
Of the twelve here this is the one with the most to do attached to it, and no restriction applies to dogs in any month. The trade is exposure. The beach faces north and takes northerly swell on the chin, so a day with wind in that quarter is not the day to plan a long paddle. Car parks near the harbour handle the numbers, public toilets are on hand, and the chippers are genuinely worth the detour.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand and shingle
- Tides: North facing, can be exposed to northerly swells
- Parking: Car parks near the harbour and the beach
- Facilities: Cafes, pubs, chippy, shops, lighthouse and public toilets
- Nearest dog beach: Orlock Beach, 1.7 miles
- Best for: Pairing a beach hour with a proper town lunch
Orlock Beach, Groomsport
Orlock Point sits at the tip of the Bangor headland where the Irish Sea turns into Belfast Lough, and the shore here is rock and shingle rather than anything you would call a beach. The North Down Coastal Path runs straight through it. Views cross the water to the Antrim hills, and on a rough day the whole headland is worth the visit for the weather alone.
Call this one an exploring beach rather than a running beach, because the ground rewards a dog that noses through gullies and pools and frustrates one that wants a flat sprint. Low tide opens up considerably more of it. The honest limits are that parking is roadside near the point, nothing on site supplies anything, and the terrain is hard going for a dog with stiff hips. Groomsport and Bangor cover facilities between them.
- Dog access: Year round, no seasonal restriction
- Terrain: Rock and shingle
- Tides: Rocky headland, best explored at low tide, exposed to northerly conditions
- Parking: Roadside parking near Orlock Point
- Facilities: None, Groomsport and Bangor for amenities
- Nearest dog beach: Donaghadee Beach, 1.7 miles
- Best for: Scrambling, scenting and coastal path walking
Ballyholme Beach, Bangor
A broad, sheltered bay on the eastern side of Bangor, backed by a promenade and the residential esplanade above it. The water is calm enough that the Royal North of Ireland Yacht Club keeps its sailing here, and the beach is among the most used in the Greater Belfast area for exactly that reason. It is a town beach with the manners of one.
Access runs year round, with no seasonal closure of the kind that shuts resort beaches elsewhere, but Ards and North Down Borough Council dog control orders do require leads on the designated promenade areas. The sand itself is dog friendly and the bay is a reliable calm water option when the open coast is unusable. Popularity is the other consideration, since no other beach here draws the same numbers and a warm Saturday shows it. Cafes and toilets are on the promenade.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand
- Tides: Sheltered bay, very calm, popular sailing water
- Restrictions: Leads required on designated promenade areas under council dog control orders
- Parking: Car parks along Ballyholme Esplanade
- Facilities: Promenade cafes, yacht club, public toilets
- Nearest dog beach: Bangor Beach, 0.5 miles
- Best for: Flat calm water within reach of Belfast
Bangor Beach
Bangor's own beach sits beside one of the largest marinas in Ireland, with the promenade, the town and the regenerated waterfront immediately behind it. The breakwaters keep the bay calm in most conditions. For anyone basing a trip on the North Down coast this is the practical beach, five minutes from restaurants, shops and a car park that is never entirely full.
Dogs are allowed on it throughout the year. Set against that, the council dog control orders that apply across the town require leads on the promenade and in the town areas, and the marina traffic and general bustle of the seafront make this a poor choice for a dog that finds crowds difficult. Ballyholme, half a mile east, is the better option if what you want is space rather than amenities, and the walk between the two is a pleasant thing in itself.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand
- Tides: Bangor Bay, sheltered by marina breakwaters, generally calm
- Restrictions: Leads required in promenade and town areas under council dog control orders
- Parking: Multiple car parks in the town centre and at the marina
- Facilities: Full resort amenities, marina, cafes, restaurants, pubs, shops, toilets
- Nearest dog beach: Ballyholme Beach, 0.5 miles
- Best for: A beach with a town attached, when convenience is the object
Helens Bay Beach, Bangor
Helen's Bay is the sandy beach inside Crawfordsburn Country Park, one of the oldest and most visited country parks in Northern Ireland. It faces north across Belfast Lough with wooded slopes rising directly behind the sand, and Grey Point Fort, a First World War coastal battery, stands on the headland above. Picnic areas and a cafe sit within the park.
The park is not under the borough council's dog control jurisdiction, and year round access is the reported position, but park management may ask for dogs on leads in certain areas so the signage at the entrance is the thing to read on arrival. What the setting buys you is shelter and variety in one stop: woodland paths, a graded beach and a coastal path that carries on in both directions. The car park may charge.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand
- Tides: North facing Belfast Lough beach, generally sheltered
- Restrictions: Country park may require leads in certain areas, check park signage
- Parking: Country park car park at the entrance, charge may apply
- Facilities: Country park cafe, toilets, picnic areas, Grey Point Fort
- Nearest dog beach: Crawfordsburn Beach, 0.5 miles
- Best for: Combining woodland and sand without moving the car
Crawfordsburn Beach, Bangor
Half a mile west of Helen's Bay and inside the same country park, Crawfordsburn has the wooded glen of the Crawfordsburn river coming down to meet it. The path linking the two beaches along the shore is one of the better short walks anywhere in the county, and doing both in one visit takes under an hour at an unhurried pace.
Access holds all year, with the same proviso that the park may require leads in places. Take the two beaches as a single outing rather than separate trips, because they are close enough that choosing between them is a false question and the connecting path is the best part of either. The country park has a visitor centre, cafe and toilets, which makes this the easiest beach on the list to visit in winter with a dog that will need drying off.
- Dog access: Year round, no seasonal restriction
- Terrain: Sand
- Tides: Belfast Lough, sheltered conditions
- Restrictions: Country park may require dogs on leads in certain areas
- Parking: Crawfordsburn Country Park car park
- Facilities: Cafe, toilets, visitor centre, picnic areas
- Nearest dog beach: Helens Bay Beach, 0.5 miles
- Best for: A winter walk with facilities at both ends
Greencastle Beach, Newtownabbey
The one entry on this list that is not in County Down. Greencastle sits on the Antrim side of Belfast Lough, a small shingle and rock shoreline near the pier with the coastal path running alongside and the Down coast visible over the water. It is a local walking spot rather than a beach anyone drives to, and it earns its place here because it sits within easy reach of the Belfast Lough beaches above.
No restrictions are confirmed and access is year round. Manage your expectations though, because this is a working shoreline on the edge of a city rather than a stretch of sand, with limited local parking, nothing on site and Carrickfergus or Newtownabbey needed for amenities. Its value is as a short weekday leg stretch with a view, and as proof that the lough has useable shore on both of its sides.
- Dog access: Year round, no seasonal restriction
- Terrain: Shingle and rock
- Tides: Belfast Lough shoreline, sheltered
- Parking: Limited local parking
- Facilities: None on site, Carrickfergus and Newtownabbey for amenities
- Nearest dog beach: Helens Bay Beach, 7.6 miles
- Best for: A short lough shore walk on the Antrim side
Practical Advice for Year Round Beach Days in County Down
Year round access is a legal position, not a guarantee about the day itself. These five things decide whether the trip works.
- Year round does not always mean off lead. Ballyholme and Bangor both sit under borough council dog control orders that require leads on the promenade, and the two country park beaches may ask for them in places. Read the signage at the entrance rather than assuming.
- Ring ahead for Ballykinler. It shares ground with a military training area and access changes with the schedule. The two mile drive round to Tyrella is the fallback.
- The south coast and the lough are different climates. Tyrella and Ballykinler take southerly swell, Donaghadee and Orlock take northerly. Belfast Lough stays calm through most of what either of those throws at it, which is the reason to keep Crawfordsburn in reserve.
- Six of the twelve have nothing on site. Tyrella, Ballykinler, Ballywalter, Orlock and Greencastle supply no water, no toilets and no shelter. Carry what the dog will need.
- Pair them up. Tyrella with Ballykinler, the two Millisle beaches, Donaghadee with Orlock, Bangor with Ballyholme, Helen's Bay with Crawfordsburn. Every one of those pairs is under three miles apart and several are walkable.

What's Nearby?
If County Down is one leg of a longer trip, the guides below pick up the coast and the hills on either side of it:
- Dog friendly beaches in Northern Ireland: The wider picture across all six counties, including the Causeway Coast strands that County Down cannot match for scale.
- Dog friendly walks in Northern Ireland: Inland routes through the Mournes and the Antrim glens, for the days when the wind makes the coast a bad idea.
- The Causeway Coastal Route: The drive north from Belfast, useful if you are treating Greencastle and the lough as the start of something longer.
- Dog friendly beaches in Scotland: Twenty one miles from Donaghadee across the North Channel, and the obvious continuation if you are taking the ferry.
- Dog friendly beaches in Cornwall with no summer ban: The same year round test applied at the other end of these islands, where seasonal orders are far more common.
Everything here is browsable by region as well, starting with dog friendly beaches in County Down, or from the whole directory.
Final Thoughts
County Down will not out-scale the Causeway Coast and it does not try to. What it holds instead is a short run of shoreline where the rules stay the same in every month, within half an hour of Belfast for most of its length.
If you want the best of it in one visit, Tyrella under the Mournes is the beach worth the drive south, and Ballykinler doubles it when the range is quiet. If you are living locally and want somewhere for a Tuesday evening, Helen's Bay and Crawfordsburn are the pair that work in the dark and the wet. If your dog is elderly, nervous or new to water, Millisle Lagoon asks least of it. And if the wind has ruined everything else, the lough beaches at Ballyholme and Bangor will still be flat, lead in hand on the promenade.
