FATMAP difficulty grade
From the Glen Nevis car park, follow the path along Glen Nevis and past the impressive Steall Falls.
At 120m this is the second highest in Britain, and some may wish to make a slight detour over the wire bridge to stand below it and witness it close up.
Continue along the glen until Steall ruin.
From here head steeply up to Sgurr a' Bhuic; this is by far the longest ascent of the day.
The descent is tricky - here you must use your judgement to find the best way down to the col below Stob Coire Bhealaich.
This is the hardest descent of the day and would be difficult in poor visibility.
Now just follow the Grey Corries ridge over one summit after another, as the blue line suggests.
It's a mixture of broad rolling ridges and some slightly steeper, more rocky terrain.
Keeping on top of navigation is important, as even in good visibility it would be possible to be drawn onto the wrong ridge from the top of some summits.
From Stob Choire Claurigh those with spare energy might make a short(ish) there-and-back detour to the outlying summit of Stob Coire na Ceannain - this is the best bit of scrambly ridge on the Grey Corries.
To complete the circuit make the long descend SE and then S onto the bealach at the head of Coire Claurigh, then climb Stob Ban as a last sting in the tail.
It's more or less all downhill from here. From the top of Stob Ban, descend SW to Glen Nevis and walk out along the mostly good but sometimes boggy path along Glen Nevis.
Alternatively, descend to the East of Stob Ban to stay the night in the Lairig Leacach bothy. © willoates - UKHillwalking.com, Feb 2012.
