🥾 Step-by-Step Walk Guide

🚗 Start at Slieve Donard Car Park

Begin your adventure from the main car park in Newcastle and follow the well-used path uphill towards Donard Wood.

This easy opening section allows you to warm up before the climb begins.

🌲 Walk Through Donard Wood

The trail winds through beautiful woodland filled with oak, birch and Scots pine.

Cross several charming bridges as the path follows the cascading Glen River, creating a peaceful start to the walk.

Keep an eye out for birds and wildlife hiding amongst the trees.

⛰️ Begin the Mountain Ascent

Leaving the forest behind, the gradient starts to increase as the route climbs alongside the river.

This is where the challenge begins.

The path becomes steeper and rockier, with several viewpoints opening up behind you across Newcastle and Dundrum Bay.

Take your time and enjoy the scenery.

🏞️ Reach the Saddle

Continue climbing until you reach the saddle between Slieve Donard and Slieve Commedagh.

The recently improved stone steps make this section easier than it once was while protecting the mountain from erosion.

This is an excellent place to stop, catch your breath and admire the surrounding peaks.

🧱 Follow the Famous Mourne Wall

Cross the final stream and join the legendary Mourne Wall, one of Ireland’s greatest engineering achievements.

Turn left and follow the wall uphill.

Although you’ll cross several false summits, don’t be discouraged — the highest point is still ahead.

The final climb is steep but unforgettable.

🏔️ Reach the Summit

After one last push you’ll arrive at the summit shelter, trig point and ancient cairns marking the highest point in Northern Ireland.

At 850 metres, the views are nothing short of spectacular.

On a clear day you can see:

• The entire Mourne Mountain range
• Newcastle and Dundrum Bay
• The Irish Sea
• The Isle of Man
• The mountains of Scotland

This is one of those summits you’ll remember forever.

🔙 Return Journey

Retrace your steps back along the Mourne Wall to the saddle before descending via the Glen River path.

Take extra care on the steeper sections, particularly after rain, as the rocks and steps can become slippery.
