In reply to aldo56:
Hi aldo56, I read that guide but then had a series of mishaps:
left it in the car, walked up to CIC because I wanted more water, then went too high up from there above the rock terrace, leading me to miss out the first section of the ridge. Bit of a bugger crossing the scree higher up which didn't add any pleasure to the route.
Then descending, all I could remember from the guide was to 'head up and across', which was pretty vague at that point, I then didn't head up far enough (I think) and had to wade up and across/ traverse a boulder gully, then over a steep patch of snow - sans ice axe or crampons, just kicking steps as it started to hail. Went over the brow of Carn Dearg between the far crags and hit another wide patch of steeper snow, stupidly crossing it rather than going further up another boulder field... and feeling stupidly bumbly.
I'd like to know where I went wrong, apart from leaving the guide book! Should I have gone further up to Carn Dearg to the summit? Should I have clambered up the boulder field higher after that towards the walkers path rather than walk across the snow packed slope? Sorry if these are daft questions but I'm trying to learn from my mistakes!
I still think Castle Ridge was harder than Tower Ridge, everything about Tower Ridge was the right side of exhilarating!
