In reply to echo34:
I loved the Cuillin when I was actively walking and scrambling. Someone though can correct me if the suggestions below are harder than grade 2/3 scrambles as I’ve not been to the Cuillin for quite a few years. Memory can be selective!
So many favourites, but one particular one that’s not been mentioned so far is the West ridge of Sgurr Nan Gillean. Either one way (using the “tourist” path for in or out) or two way via Bealach Bhasteir. As an add on Am Basteir can be done up and down as well. Suggest a rope/basic gear though for the bad step. There is also Pinnacle ridge up to the west ridge, but my memory is that’s it’s at the hard end of scrambling (and a rope abseil is involved).
Another one that’s less travelled that I enjoyed; Sgurr Thuilm to Sgurr a Mhadaidh, but I recall considerable exposure and full on grade 3 in a section if sticking to ridge. Not one for poor weather.

Plenty of things to be careful of up in the Cuillin, but the generalisation “gabbro good, basalt bad” is worth remembering I always thought. The latter can be very slippery.
Routes can and do take much longer than the inexperienced expect, they can be very tiring, and some require very careful route finding. There used to be, and no doubt still are, a lot of “false tracks” - well worn tracks leading nowhere or no where anyone inexperienced should be going.
Also, if you are a hands on rock a lot person whilst scrambling you may find gloves useful if your skin is not used to the rough rock. A few friends used to destroy a pair of gloves in a day!
HTH a little.
