Carn Mor Dearg Arete (Summer): Grade 1 Grade reference

Route overview

This celebrated horseshoe route offers a superb and physically demanding way to ascend Ben Nevis, bypassing the busy mountain track for a grand mountain day. Starting from the north, the route climbs Càrn Mòr Dearg before traversing the famous, sweeping arête. It provides an elegant line and peerless views of the formidable North Face cliffs.

Terrain and underfoot

The route follows clear forest tracks and mountain paths initially, transitioning to a steep, boggy ascent up Càrn Mòr Dearg. The arête itself requires sustained but straightforward scrambling over large blocks with significant exposure. The final climb to the Ben Nevis plateau is a steep, rough boulder field. The descent uses the well-made tourist path before a rough, pathless section leading to a potentially difficult crossing of the Allt a'Mhuillin.
