Hiking

Embark on a challenging hike up Ben Nevis via the Càrn Mòr Dearg Arête, a difficult route spanning 11.1 miles (17.9 km). This adventure involves a significant elevation gain of 4669 feet (1423 metres) and typically takes around 7 hours and 58 minutes to complete. As you traverse the exposed arête, you will experience dramatic drops on both sides, offering expansive views of the Scottish Highlands and the majestic North Face of Ben Nevis.

This demanding trail is best suited for experienced mountain walkers who are in good physical shape and comfortable with heights. It is not recommended for beginners due to its technical sections and exposure. If you plan to hike in winter, you must carry an ice axe and crampons, and possess the skills to use them safely. Always be prepared for rapidly changing weather conditions and challenging navigation, especially if visibility is poor.

Many consider this the most rewarding way to ascend Ben Nevis, offering a unique perspective of the UK's highest peak. From the summit of Càrn Mòr Dearg, you gain an exceptional vantage point, providing superb views of Ben Nevis itself and a full 360-degree panorama of the surrounding landscape. Even when clouds obscure the peaks, the rugged beauty of the area maintains an otherworldly magnificence.

Carn Dearg Meadhonach

Highlight • Viewpoint

Arrival at Càrn Dearg Meadhonach is a relief if you've slogged your way up from the North Face Path, as it means it’s only a short way to Càrn Mòr Dearg striking pyramid and its famous arête. The views from this subsidiary summit are wonderful, particularly across to the muscular bulk of the Ben's North Face.

Càrn Dearg Meadhonach's east ridge is a superb alternative way to access its summit. A rough grade one scramble in summer, it's a fine grade two winter route.

Càrn Mòr Dearg

Highlight • Climb

Càrn Mòr Dearg is a 4,000-foot (1,220 m) Munro in the Scottish Highlands. It is often climbed alongside Ben Nevis. The ridge that links the two Munros is the CMD Arête, a grade one scramble. From the summit of Càrn Mòr Dearg you get a fine view over to Ben Nevis and also Aonach Mor and Aonach Beag.

Carn Mor Dearg Arête

Highlight • Viewpoint

A simply sensational grade one scramble, set against arguably the most awesome mountain backdrop in Britain: the North Face of the Ben. The Càrn Mòr Dearg Arête' hangs like Britain's most exciting washing line between Càrn Mòr Dearg and the summit slopes of Ben Nevis.

It is not as exposed as the Aonach Eagach or even Crib Goch in Wales and there's often a bypass path to one side of the crest. In winter, the ante is well and truly upped – one for those with the relevant skills and equipment. However, if the sun is shining and you're a confident hiker, this is a much more satisfying route up Ben Nevis than the Pony Track.

Ben Nevis summit

Highlight • Summit

Ben Nevis is Britain's highest mountain and arguably its greatest from a mountaineering perspective too. This is mostly down to its immense North Face, a treasure trove of ridges, buttresses and gullies that climbers have been testing themselves on for generations.

Leaving the summit in poor visibility during winter poses significant dangers due to the cornices that form on the Ben's gullies. The safest way off is to walk on a bearing of 231 degrees for 492 feet (150 m) from the summit trig point. Then, walk on a bearing of 282 degrees to intercept the zig zags of the Pony Track.

May 6, 2025,Ben Nevis via The Ridge
Happy to tick this off the list, in typical fashion the cloud moved in and spoilt some of the views but the actual route along the ridge was superb
A really beautiful hike at the beginning, despite the moor, which was extremely strenuous to hike through. The K1 climbing section in particular was indescribably beautiful.
From the summit it was tourist hell, because of a very well-developed path from Glen Nevis above. Queuing at the summit for a photo. Going down in crowds. But the view from the top …

Total hiking time of 10 hours, with a few breaks.
A nice steady climb from the North Face car park to the Càrn Dearg Meadhonach 1180 m, then not far from the Munro Càrn Mor Dearg 1220 m with the famous ridge. The path from the CMD Arête over the rocks/cliffs to the Ben Nevis plateau was very strenuous, there …

Ben Nevis via Càrn Mor Dearg and the CMD arete. The best of days 🥰 a tad breezy on the ridge but never enough to make me want to put a jacket on. Joined by Chris and Ben.
At 1370 metres, Ben Nevis is the highest peak in the United Kingdom, or in all of Britain.
You might like to laugh at that, but you should note that the climb is not to be sneezed at (unless you take the boring zig-zag path from the south).
To avoid the majority of hikers, we started from the north side …
