In reply to nik king:
A nice short day might be to go up to Glyder Fawr via Y Gribin (from the Idwal side), then down via Senior's Gully (barely a scramble) - of course you have the option of an out-and back to Glyder Fach with some easy scrambling over Castell y Gwynt if you like.
The Llech Ddu spur is usually quiet, and any harder steps are avoidable: it's a bit of a tramp from Bethesda but lovely once you're on it and there are options to visit Carnedd Llewellyn and Yr Elen to make a circuit, or simply head down the long arm of Carnedd Dafydd for a short day.
For an alternative Snowdon "horseshoe" without the exposure, you could go up the (other) Gribin and continue over Lliwedd: all good grade 1 fun.
Another option, with harder route-finding, from Nant Peris or thereabouts would be a scramble up Llechog , continuing to Garnedd Ugain before descending via the Cwm Glas spur.
