Three Beinns Horseshoe

This horseshoe is one of the classic Arran walks, taking in a semicircle of high ridges running between Beinn Nuis, Beinn Tarsuinn and Beinn a’Chliabhain. Starting in Glen Rosa, this is a perfect day out as an introduction into the Northern hills, with stunning views that stretch out over the western hills, taking in the lowlands of the south of Arran and the majestic peaks and ridges of the highest northern hills.

 | Overview


Highest Point Gained
826m - Beinn Tarsuinn

Total Ascent

Walk Duration

Head for heights required - ridges with steep drops. Rough mountain paths, boggy moorland, hands-on clambering, steep sections with loose rock underfoot.

Technical Rating
Easy scrambling, elements of exposure, some rough terrain.

Endurance Rating
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 route climbs steeply up alongside the Garbh Allt burn, flattens out across moorland before the path heads uphill again, threading around and over boulders and slabs to reach the summit of Beinn Nuis, the first of the Three Beinns.

From there, the walk follows the ridge round to Beinn Tarsuinn, now gently undulating. Just before the summit, the characterful Old Man of Tarsuinn is encountered, an outcrop naturally sculpted into a human profile, which appears to look out to sea over Brodick. There is then a steep descent to Bealach an Fhir-bhogha with some hands-on rock clambering and negotiation of substantial boulders before the path turns onto gentler terrain and follows a grassy ridge up to Beinn a’Chliabhain. From the rocky tors of the last of the three Beinns, the trail heads back down onto the moor and rejoins the Garbh Allt stream to descend back into Glen Rosa.

Along the way, there is a good chance of spying mountain wildlife, from birds of prey and raven soaring high in the thermals to the abundant red deer grazing the sheltered slopes and corries.
