In reply to Pmcnbear:
It's a serious grade 3 scramble, lots of exposure at a couple of sections, a fall from quite a lot of it would almost certainly be terminal, it would not be easy to escape from, and has danger of rockfall especially on the approach. Not a family day for most families.
On the plus side the crux is short and easily protectable. However it doesn't really sound like you know what you're doing with a rope (apologies if I'm making unfair assumptions) so that may be moot.
I do a lot of this sort of thing and would think very hard before taking my capable 12-year-old on Curved Ridge. Actually I almost certainly wouldn't, because I'd want them to be roped up the whole way and that is either hard to do safely when moving together or very time consuming if you're pitching. Perhaps my risk aversion is too high when it comes to the kids but I would definitely be more scared than they were, and that's not what I'd call a fun day out.
A much more child-friendly scramble in that area is Pink Rib on Beinn a' Chrulaiste
