In reply to boulderlad:
You could fly to Nice, Genova (closest), Turin or Milan and hire a car.
Alternatively arrive by rail from Genova or Nice and get a taxi up to the Monte Cucco campsite. There are supermarkets in Finale, but none close to the campsite, which was opposite a pizza restaurant, that was open when we were there in August 1998. There was a climbing shop in Final Borgo where we got the guidebook.
The campsite had cold showers, wash basins and a reliable water supply.
I have a sketch map of the campsite location. If you'd like a copy of it send me an email and I'll scan it for you.
The weather is variable in December/Jan. If you are lucky it will be dry.
