Plan your visit

The trail itself: 37km of mountain off-road

The full Mourne Way runs about 37km (23 miles) from Newcastle to Rostrevor, almost entirely off-road. Expect forest track, faint grassy mountain paths and stretches of open hillside, with some genuinely wet, boggy ground in the high sections. It is graded very strenuous, with sustained steep climbs and descents and rough, uneven terrain throughout. The highest point is around 500m on Butter Mountain, and parts of the route cross open mountainside with little or no waymarking, so you need proper hill gear, a map and navigation skills. Along the way you pass Tollymore Forest Park, Meelmore Lodge, Spelga and Fofanny reservoirs, and finish through the pine woods of Kilbroney Park above Carlingford Lough.

The story

About this trail

The Mourne Way links Newcastle on the Irish Sea with Rostrevor on Carlingford Lough, tracing the foothills around the western and northern edge of the Mourne Mountains. It is one of Northern Ireland's waymarked long-distance walking routes, crossing a largely granite landscape shaped by ice and by generations of work in the hills.

Along the way the route picks up older paths with real history. The Trassey Track was part of the old Brandy Pad, an 18th and 19th century smuggling route through the mountains, while the finish near Kilbroney connects to St Bronach's 6th-century convent at Rostrevor. The walk also passes the Fofanny and Spelga reservoirs, the Spelga dam being completed in 1957.

From urban parkland and deciduous woodland at Tollymore, through open mountain and bog, to the thickly planted pines of Rostrevor Forest, the route delivers wide views of coast, sea and the Kilbroney valley toward Carlingford Lough.
