Slievemartin

About Slievemartin

Overlooking the village of Rostrevor, this western outpost of the Mournes offers a gentler character than the range’s rocky interior. While much of the ascent follows forest tracks through Kilbroney Park, the open summit reveals a spectacular perspective across Carlingford Lough toward the Cooley Mountains of Louth.
