Details:
The list of Grade 1 Gullies was a hybrid of the SMC Ben Nevis guidebook and the UKC Logbook. Not much info out there about Arch Gully, on Carn Dearg Summit Buttresses - quite cool with a big chockstone.
My Route:
Start North Face car park
Up No. 5 Gully
Down Colando Gully
Up Arch Gully
Down No. 4 Gully
Up No. 3 Gully
Down Tower Gully
Up East Gully of Douglas Boulder
Down West Gully of Douglas Boulder
Finish North Face car park
I didn't include CMD Arete as I think you can argue that its not really 'on' the Ben.
