Areas / The Mourne Mountains
The Mourne Mountains
The Mournes rise straight up from the coast — granite peaks, forest, and a 22-mile dry stone wall that's been standing since 1922. Newcastle, at the foot of Slieve Donard, is the easiest way in, and it's close enough to make a proper day of it without an early start.
A few things worth knowing
Grouped the way we'd tell a friend, not the way a brochure would.
Slieve Donard
Northern Ireland's highest peak at 850 metres. A well-marked trail up from Newcastle, with the reward of a proper panoramic view at the top.
Tollymore Forest Park
A 630-hectare forest at the foot of the mountains — hanging trees, quiet trails, and enough atmosphere to feel like a different world entirely.
The Cloughmore Stone
A 50-tonne granite boulder with a local legend attached — supposedly thrown across the lough by the giant Fionn mac Cumhaill. The views over Carlingford Lough from here are some of the best around.
Newcastle town
A seaside town at the foot of Slieve Donard, with an easy promenade, independent shops, and a proper arcade or two for a rainy day.

A few questions people ask
Is Slieve Donard hard to climb?
Slieve Donard is a moderate to strenuous hike, with a well-defined but steep trail and rough terrain near the summit. It's manageable for hikers with reasonable fitness, but not a casual walk.
How long does it take to climb Slieve Donard?
The hike takes around 4-6 hours round trip. The trail is 4.6km each way from Donard Park in Newcastle, making a 9.2km round trip in total.
Where do you park for Slieve Donard?
Donard Park in Newcastle is the main car park and is free, but it fills quickly on weekends and bank holidays — arrive before 9am in summer.
What can you see from the top of Slieve Donard?
On a clear day, the summit (850m, Northern Ireland's highest peak) offers views of England, Scotland, Wales, and Strangford Lough.
When is the best time to hike the Mourne Mountains?
Mild, dry weather is best given the exposed, rocky terrain near the summit — conditions in the Mournes change quickly, so check forecasts before heading out.
