If you love scrambling and have a head for heights, this is THE walk not to be missed! 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 possibly even abseiling.
Distance: 15km
Ascent: 800m
Walk duration: 9hrs
Technical grading: Extreme
Blister Rating: 3
Walk description: There is plenty of time to warm up before the going gets tough: The track into Glen Rosa makes for a gentle start. Soon you'll head uphill though, leaving the main path to clamber up the steep slopes of the Garbh Allt burn, then heading higher still to the summit of Beinn a'Chliabhain (653m). From its lofty heights, you'll be able to admire the craggy ridge you'll soon attempt to scale. With a bit of luck, the stunning views and maybe even an encounter with mountain wildlife such as red deer and golden eagle might take your mind off the challenge ahead, because lets face it: You'll be excited, but also a wee bit nervous of what lies ahead! The ridge looks even more imposing as some height is lost descending down to the col. The first section to the summit stone of A'Chir (745m) is the easiest bit... By now, the adrenaline should be kicking in! Just as well that bad steps and tricky moves can be made negotiable by an experienced leader and some climbing rope!
The descent will take you into Fionn Choire, with Cir Mhor towering to the north. The path follows a tributary of the Rosa Burn, which will keep you company all the way down the glen.
This walk will be led by a fully qualified mountaineering instructor.
You MUST have a good level of fitness, a head for heights and previous scrambling experience to take part.
A full traverse of the A'Chir ridge is dependant on good conditions on the day. In the interest of group safety, the route may be adapted accordingly.
