Carn Mor Dearg: Ben Nevis's Nearest Munro Neighbour

Càrn Mòr Dearg, affectionately known as CMD, is a Munro that commands respect. As the 8th highest peak in Scotland, standing at an impressive 1,220 metres, it offers a challenging ascent with unparalleled views of Ben Nevis's dramatic North Face. The name, meaning "big red hill" in Gaelic, is a nod to its granite composition and rugged character. For those seeking a strenuous adventure with jaw-dropping rewards, Càrn Mòr Dearg stands proudly as Ben Nevis’s nearest Munro neighbour and a gateway to the legendary CMD Arête. Whether tackled as a standalone summit or combined with Ben Nevis, this hike delivers one of Scotland’s most exhilarating mountain experiences.

Route Overview

The most popular approach to Càrn Mòr Dearg begins at the North Face Car Park near Torlundy, following the Allt a’ Mhuilinn path. This route covers approximately 14 kilometres as a return trip, with an elevation gain of around 1,100 metres. For fit hillwalkers, the round trip typically takes 6 to 8 hours. However, many choose to extend the adventure by traversing the iconic CMD Arête to Ben Nevis, creating a roughly 18- to 19-kilometre loop with an ascent of over 1,400 metres.

The trek is classified as strenuous, featuring boggy sections, steep climbs, and exposed ridge walking. It is ideal for experienced hillwalkers comfortable with grade 1 scrambling and confident on airy terrain. During the summer, the route is best tackled in clear weather to make the most of its stunning views, although winter ascents are possible with proper equipment and skills.

The Walk

Stage 1: From the Car Park to the Open Hillside

From the North Face Car Park (grid reference NN 145 747), cross the bridge over the River Nevis and turn right, following signs for the North Face Trail. You will soon join the Puggy Line, a well-maintained forest track that rises gently through pine woodland. Although the gradient is moderate, the enclosed forest can feel humid in summer, and midges are often present. After around 2 to 3 kilometres, the path emerges from the trees, revealing the open hillside and your first clear sight of Ben Nevis’s towering North Face.

Stage 2: The Ascent to Càrn Mòr Dearg's East Ridge

Turn left at a marked path junction to follow the Allt a’ Mhuilinn trail, which begins to climb more steeply. The terrain here is boggy, especially after rain, so gaiters are highly recommended. As you gain altitude, the ground becomes firmer, and the incredible cliffs of Ben Nevis dominate your view. The CIC Hut, a popular base for climbers, lies ahead, but walkers aiming for Càrn Mòr Dearg will veer right before reaching it, ascending the eastern flank of the mountain. This section is strenuous but straightforward, with grassy slopes giving way to rockier ground as you approach the ridge.

Stage 3: The Summit of Càrn Mòr Dearg

The summit, marked by a cairn, is a truly spectacular vantage point. From here, you are treated to unrivalled views of Ben Nevis’s North Face, with its towering cliffs and craggy gullies. On a clear day, the panorama extends to Loch Linnhe, Loch Eil, and the Mamores to the south. The ridge leading toward the CMD Arête is also visible, enticing those with the energy and experience to continue their journey. For those opting to make Càrn Mòr Dearg a standalone objective, the descent retraces the same route back to the car park.

Stage 4: The CMD Arête to Ben Nevis (Optional Extension)

For those continuing, the CMD Arête offers an unforgettable ridge traverse. The narrow, rocky ridge requires good balance and a steady nerve, with some scrambling needed on exposed sections. As you approach Carn Dearg Meadhonach (1,180m), the ridge broadens slightly before the final climb to Ben Nevis begins. This section is a relentless ascent over rocky terrain, eventually leading to the summit plateau. From Ben Nevis’s summit cairn, descend via the zig-zags of the tourist path to rejoin the North Face trail for the return to the car park.

Getting There and Parking

The North Face Car Park is the most convenient starting point for the Càrn Mòr Dearg walk. Located just off the A82 near Torlundy, it offers free parking but has limited spaces, so an early arrival (before 8am) is advised, especially in summer. Alternative starts include the Glen Nevis Youth Hostel car park (grid reference NN 125 722), which adds extra distance and elevation but may offer more parking availability.

Access is generally straightforward, but the Glen Nevis road can be affected by landslips, so check conditions before travelling. Public transport options are limited, but taxis from Fort William can drop you close to the North Face car park if needed.
