In reply to TBBroatch:
Do you mean stuff you would actually do in the winter season? Not much if any that's worth doing and it's more serious. You'd need skis to get to and from the routes for a start.
If you mean snow/ice/mixed stuff that you can do in the summer (conditions permitting), there are a lot of routes in the PD to AD range that would fit the bill. It won't be pure ice though.
