There are three ski stations: Ghisoni, Val d'Ese and the newly reopened Haut Asco with a combined total of seven lifts and just over 10km (yes, ten) of prepared pistes - it's very much a niche piste skiing destination!
We skied at Asco where the long ago established ski station has reopened with a brand new button lift and two prepared runs. You can rent all you need and get a day ski pass for around 35 euros. There is a very nice restaurant and hotel at the base which is open year round - I highly recommend the Corsican soup.
The untapped attraction of snow en Corse is ski touring and off piste adventures - there are great rafts of untouched terrain and once you're there some of it easily accessible such as Restonica out of Corte. A guide of course, as well as the right equipment is essential given the remoteness.
The weekend was topped off with some great hiking in and around the coast Revellata and of course the obligatory bike ride - now you can't do that in Val d'Isere in February!
