The Mourne Mountains — Peaks, Forests, and Narnia
An Area of Outstanding Natural Beauty in County Down, the Mournes are said to have inspired C.S. Lewis's Narnia — and standing at the foot of Slieve Donard with mist rolling across granite peaks, you can see why. These are proper mountains, compact and dramatic, rising straight from the Irish Sea to nearly 3,000 feet.
Belfast to Newcastle — the gateway town at the foot of the Mournes — takes under an hour via the A24. The drive south through Ballynahinch and past Castlewellan is quietly beautiful, with rolling farmland giving way to the mountain skyline ahead.
Walks and Trails
Slieve Donard
Northern Ireland's highest peak at 850 metres. The main trail starts from Donard Park in Newcastle and follows the Glen River through ancient woodland before climbing to the summit. Budget four to five hours return. The views from the top stretch across six counties on a clear day — you can see Scotland, the Isle of Man, and the Wicklow Mountains in the Republic.
Tollymore Forest Park
One of Northern Ireland's finest walks — stone bridges, Gothic follies, river paths beneath ancient trees. Game of Thrones fans will recognise it as the Haunted Forest, and on a misty morning the atmosphere is exactly as eerie as it looks on screen. Entry fee per car. Multiple trails from one to five miles. The Mournes also feature on our day trips from Belfast guide alongside the Giant's Causeway and Dark Hedges.
Silent Valley Reservoir
Deeper in the Mournes, Silent Valley offers a peaceful circular walk around the reservoir with mountain views in every direction. The Mourne Wall — a granite wall running over fifteen summits, built entirely by hand between 1904 and 1922 — is one of the most impressive feats of dry-stone construction you will see anywhere.
Newcastle & the Coast
Newcastle is a pleasant Victorian seaside town with a long sandy beach, excellent cafes, and the Slieve Donard Hotel at its foot. The town makes a perfect base for two or three days of walking, with pubs and restaurants that have raised their game considerably in recent years.
