Make an out-and-back beside the sea your first outing. Choose a turning point to suit the weather and your dog rather than treating the whole shore as a compulsory route.
Keep the lead short in busy areas. Promenade access is separate from beach permissions; read signs before going onto the sand.
Travel separately to the forest and choose a marked walk suited to the day. River paths, roots and slopes require more care than the promenade; shorten the route in wet conditions.
Keep close control, follow forestry and trail notices, and stay clear of river edges. Check park access and charges before travelling.
Check in and confirm where you can eat with the dog. Take a short promenade walk before dinner, allowing extra time from the cottage at the harbour end. Keep the mountains as scenery while everyone settles.
Day two · choose forest or seafront
If the weather and your dog suit a woodland walk, visit Tollymore and follow an open marked route. Otherwise repeat a shorter promenade section and leave the forest for another trip.
A suggested plan, not a booked itinerary. Adapt it to your dog, the weather and current access.

Your Newcastle (County Down) questions
Is this the Newcastle in Tyne and Wear?
No. This guide is for Newcastle in County Down, Northern Ireland, beneath the Mourne Mountains.
Where can a dog join you at Slieve Donard for meals?
Dogs may enter The Percy French and The Wolf Bar, but not J.J. Farrall’s, Lighthouse Lounge or the spa. Breakfast is served in J.J. Farrall’s, with dog-friendly seating set aside in the Wolf Bar.
Yes. The National Trust requires dogs to stay on leads across the reserve and asks visitors to avoid signed grazing and ground-nesting-bird areas. Check the signs because beach restrictions can vary by season and zone.
Is the Murlough North Point trail a short, easy walk?
It is a 3-mile (4.8 km) moderate route taking about 1 hour 15 minutes, with steeper paths, steps, stiles and beach walking; it may be uneven after rain. The National Trust allows dogs on leads. Use the marked shorter cut-backs if needed.
Do I need to climb Slieve Donard to enjoy Newcastle with a dog?
No. The guide’s promenade and lower-lying walks are alternatives to a mountain ascent. Murlough’s woodland trail is listed as an easy 1.5-mile full walk, with a 1-mile shorter option.
