MARK Ben Nevis via the Càrn Mòr Dearg Arête (CMD)
The Càrn Mòr Dearg Arête is the finest way up Ben Nevis — a long, dramatic, high-level ridge that delivers the most scenic and atmospheric ascent of the UK's highest mountain. It's exposed, rugged, and serious in poor weather, but in good conditions it's one of the best ridge walks in Britain. This is the route for walkers who want a big mountain day with real character.

The Route
🏔️ Route Character
The CMD route is a journey — long, varied, and full of drama. The day begins with a steady climb to Càrn Mòr Dearg, the elegant red peak that sits opposite Ben Nevis. From here, the route swings onto the arête: a narrow, sweeping ridge with huge drops into the North Face corries.
The ridge itself is a bit spicy but never technical — hands may be used for balance, but it's a walk, not a scramble. The views are enormous: the full sweep of the North Face cliffs, Tower Ridge, Observatory Ridge, and the summit plateau looming ahead.
The final climb to the summit of Ben Nevis is steep and bouldery, rising directly from the end of the arête. It's physical, rugged, and serious in poor visibility. The descent follows the Mountain Track, giving a long, steady finish back toward Glen Nevis and Torlundy.
