There are 4 ski areas there: Abetone, Cutigliano-Doganaccia, Cimone, Corno alle Scale.
Abetone, as you can see, is a nice place with nice slopes and lifts. The same Cimone (40-50 km of slopes ). Cutigliano-Doganaccia is 5km far from Abetone. In Cutigliano a cable car bring you on ski areas. I never went in Cutigliano but a friend of mine went there on dicember and he said me Cutigliano is just for beginner (15 km of slopes).
This is his reportage link

Corno alle Scale is nice but little ( 30 km of slopes).
Pian di Novello, as you can see in Starli's reportage, is now closed.Some politics are trying to open again slopes (15 km of slopes) and lifts, but ecologist are against this decision.
Altough I think Abetone, in Appennine, is the best ski area.
Roccaraso near Napoli or Campo Felice near Rome are very good ski resort but Abetone is better for snow.
But I thing Ischgl is better

so next week I will drive to Kappl-Ischgl-Galtur!
