The town Commune (Council) of Sarnano operate a daily bus in winter when there is skiiing on Sasso Tetto. The timetable for 2010-2011 may be seen here, along with a translation; I will upload next year's as soon as I receive it. The price for a single ticket is €3.50. The bus leaves from outside the Tourist Office in Sarnano, where the staff speak good English. Other resorts in this area include Pinatura di Bolognola, although you need your own transport to reach it. These resorts make the second largest in Le Marche for skiing, and there are 11 kilometres of tracks to ski.
There are nine lifts/tows in total, offering a reasonable variety for beginners and moderate skiers alike. There are few black runs, but there are plenty of red runs.
The only problem with the Italian Appenines as a possible ski resport, as opposed to the Dolomites in northern Italy, is that they can sometime have no snow. This is uncommon but possible - during the winter of 2008-09 there was little skiing during this season. One way around this is to take out insurance for this possibility, and then claim and put the money towards next year's skiing holiday.
