On this particular day, cyclists, on road bikes, mountain bikes, or e-bikes can cycle undisturbed over four Dolomite passes from 08.30 to 16.00. These pass roads are closed to motorised traffic. All participants will have the chance to enjoy the beautiful mountain world of the Gröden Pass, Campolongo Pass, Pordoi Pass and Sella Pass. Every year thousands of keen bike fans take advantage of the Sellaronda Bike Day to enjoy the mountain world of the Dolomites. Participation is free of charge.
