We lived near Kronplatz, in San Vigilio di Marebbe, and for one day we went to Arabba, which is relatively close. From Arabba you can ski around the Sella Ronda, or you can go over the mountain to the top of Marmolada (3250).
We went to Alta Badia for one day. If you go from Kronplatz (Vigiglio di Marebbe), then this is the closest resort in the Dolomiti superski region. There is a large free parking lot in La Villa a little further than the main lift, below, right next to the track.
We went to Kronplatz with some skepticism, because before that we had been to Sö lden and Ischgl, and clearly understood that the resort would be smaller here. But they left with a vengeance!
