A’Chir Ridge Scramble

This walk is the Arran Mountain Festival’s signature walk, and has been described as possibly the finest island ridge traverse outside Skye! If you love scrambling and have a head for heights, this is the walk for you! The A'Chir ridge is a superb mountain, easily providing the most exciting and challenging ridge traverse on Arran short of actual rock climbing routes. However, it is not to be underestimated: THIS WALK WILL EXPOSE YOU TO VERTICAL DROPS, DOWN-CLIMBING, ROPE WORK, AND MAYBE SOME ABSEILING. Come and experience Le Mauvais Pas, Pagoda Ridge, narrow grooves, awkward moves, wriggling and sliding, and exhilaration! This route is described from the north. It can be tackled from the south, however the exact route will be at the leaders' discretion on the day.

745mm - A’Chir  

Total Ascent

Walk Duration

Serious scrambling with ropes, rough mountain paths, steep sections  

Technical Rating
Ropework, extreme exposure, head for heights essential.

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

There is plenty of time to warm up before the going gets tough! The walk into Glen Rosa gives you views under A’Chir of the fine granite rock formations, and then into Fionn Choire where you can start to admire the craggy ridge as it starts to properly come into view. With a bit of luck the stunning views, and an encounter with mountain wildlife like red deer and golden eagle, might take your mind off the forthcoming challenge. Let’s face it, you’ll be excited and also a wee bit nervous of what lies ahead! By now the adrenaline should be fairly kicking in! There’s Le Mauvais Pas (don’t look down), Pagoda Ridge …… Just as well those bad steps and tricky moves are made possible by the highly experienced Mountaineering Instructor brought in specially by the Arran Mountain Festival. By now, the last section to the summit stone of A’Chir (745m) will seem like the “easy” bit…! The final stages of the walk are via the col, then onto Beinn a’Chliabhain (653m), along the Garbh Allt burn and back into Glen Rosa. You MUST have a good level of fitness, a head for heights and previous scrambling experience to take part – please do not overestimate your ability! A full traverse of the A’Chir ridge is dependent on good weather conditions on the day: in the interest of group safety, the route may be adapted accordingly. All Arran Mountain Festival walks are led by qualified Mountain Leaders.  However, due to the scrambling and ropework involved, this walk has to be led by a Mountaineering Instructor.
