I've found that a single line summarising "other interests" at the end of the CV has given me some good talking points in interviews. If your hobbies involve any sort of leadership / administrative input, this can demonstrate the skills they're after if your previous employment doesn't cover everything. For example:
"Playing in a string quartet" let me draw on working with others, liaising with clients for their requirements, punctuality, professionalism etc.
"Organising group cycle rides" meant I could talk about: scoping the route for hazards, backmarking to keep the group together, factoring in rest stops etc.
