Newcastle
The beach runs the length of the town and the Mournes stand straight behind it. Newcastle is where the Mountains of Mourne meet the sea in County Down.
Best sites to see in Newcastle
Newcastle Promenade and Beach
A long sandy beach on Dundrum Bay with a promenade, backed by the Mourne Mountains, where Slieve Donard rises directly behind the town.
Royal County Down Golf Club
A celebrated links course founded in 1889, set among dunes between the town and Dundrum Bay beneath the Mournes.
Murlough National Nature Reserve
An ancient dune system between Newcastle and Dundrum, managed for its wildlife, with boardwalks and paths through the dunes to the beach.
Tollymore Forest Park
A forest park just outside the town at Bryansford, with riverside walks along the Shimna, follies and tree-lined avenues at the foot of the Mournes.
Where to stand, and when
- The beach looking south to the Mourne Mountains: Early morning gives the clearest view of Slieve Donard rising behind the town and bay.
- The promenade at the harbour end of town: Sunset light suits the bay, the harbour and the mountains in a single frame.
- Murlough dunes and boardwalk: Late afternoon gives long shadows across the dunes and a view back to the Mournes.
Newcastle through history
Newcastle takes its name from a castle that once stood at the mouth of the River Shimna, built in the late 16th century and long since demolished.
The town developed as a seaside resort in the Victorian era, helped by the arrival of the railway from Belfast.
The songwriter Percy French celebrated the local landscape in his song about the Mountains of Mourne sweeping down to the sea.
Slieve Donard, overlooking the town, is the highest mountain in Northern Ireland at 850 metres.
Practical tips
- If you plan to climb Slieve Donard, allow several hours, carry water and waterproofs, and expect conditions on the summit to differ from the town.
- Check tide times for beach walks towards Murlough, as the sand flats are wide at low tide.
- Promenade parking fills on summer weekends, so use town car parks and walk to the seafront.
Golf near Newcastle
Royal County Down's Championship Links (£450 in 2026, £495 in 2027) sits under the Mournes at the edge of town. Visitor days are Monday, Tuesday, Thursday, Friday and Sunday, every group must take at least one caddie, and the diary opens seasons ahead. The shorter Annesley Links (£120) is the gentler way in. Ardglass, about 25 minutes north, is a cliff-top joy; the club publishes no rate card, so check with them directly.
