La Crusc Alta Badia
This was a run to try which was very highly recommended by Andrea – our travel agent she has skied here.
I agree with your points for both Lagazuoi and Marmolada (many cable cars on this one!) apart from that no other suggestions apart from maybe the Alta Badia and San Cassiano sides. Over in Badia theirs is a great and v empty long run from the top (La Crusc/Santa Croce)with a great little church and bar that is worth a quick stomp up too. Fabulous views.

Just make sure you’re on the last chair back over to La Villa so you can connect back to Corvara.
