Cir Mhor & Beinn a’Chliabhain

Cir Mhor is an iconic Arran peak dominating the view up Glen Rosa. It is sometimes known as Arran’s Matterhorn, with good reason. It is the lowest of Arran’s four Corbetts, but its very steep ascent still packs a punch!

 | Overview

Distance
15km

Highest Point Gained
799m - Cir Mhor

Total Ascent
1070m

Walk Duration
8hrs

Terrain
Rough mountain paths, steep ascents and descents with loose gravelly rock underfoot. Hands-on rock clambering up the Whin Dyke chimney. Head for heights required for Cir Mhor’s lofty summit.

Technical Rating
Moderate/Challenging  
Easy scrambling, elements of exposure, some rough terrain, but with some optional sections of more exposed scrambling for which surefootedness and a head for heights is required.

Endurance Rating
3  
Sustained steep ascents and descents, long-distance, stamina required, suitable for fit walkers. Have you had recent experience of walking for 6-8 hours? Have you recently walked up (and down) a mountain of over 1000m (3000ft) in height without physical distress? Do you regularly play an aerobic sport pretty much every week? If your answer is "No", we'd guess you'd be happier doing a walk rated a level lower than the one you’ve just read! As noted previously, we're into FUN so we don't want you to miss out by overdoing it.

 | Walk description

The walk starts gently on a meandering path along Glen Sannox which then reveals a short steep section at the head of the glen and some hands-on scrambling up the Whin Dyke to reach the Saddle, with fine views down Glen Rosa.

The route then turns up a steep path to the summit of Cir Mhor, giving more fabulous panoramic views of Arran’s mountains. From the summit the route descends and skirts around the base of A’Chir to reach Bowman’s Pass and Consolation Tor.

Next are the delightful slabs along the ridge of Beinn a’Chliabhain. From the summit the rocky path leads across a section of moorland and then down the steep Garbh Allt to Glen Rosa. From here, a track leads to the finish by Glen Rosa campsite.
