From San Cassiano set out on the SR48, which winds up to the Valparola Pass. From the top of the pass, the road is almost flat until the Falzàrego Pass, and then it winds back down to Cortina. You will enjoy great views of the peaks of the Conturines, the Lagazuoi and the Cinque Torri.

From Cortina a circular tour begins, which leads ultimately to the famous Three Peaks. Cycle along the Strada delle Dolomiti, the SS48, to the pass of the Passo Tre Croci. The road has a few interesting ascents, with the average gradient being about 3 %.

From the Passo Tre Croci ride down towards Misurina and Auronzo, and at the junction bear left towards Misurina. After a steep but short climb, you reach the Lago di Misurina lake. From Misurina head to the Lago d’Antorno, first along a level road and then steeply uphill at the end. After a short, easy descent, you reach the steepest part of the tour. Proceed steeply uphill for about 4 kilometres to the foot of the Tre Cime di Lavaredo. After a rest, continue on the same road down to Misurina, and then an easier section via Carbonin, Cimabanche and Fiames takes you back to Cortina.

From Cortina head over the Falzarego Pass, the last tiring climb of the tour, and then down from the Valparola Pass back to San Cassiano.
