“The western section of the Sellaronda passing through the Passo Sella heading north.”

From Campitello di Fassa, take the Col Rodella cable car to the upper station. As usual, there are several rifugi (mountain huts) along the route, including two just near the top. From the cable car, take the gravel road about 0.5 mi down to the three-way intersection. Near this intersection, beware of a massive cow!
If you survive the encounter with the cow, take the singletrack that begins at the three-way intersection. This will take you down to the Passo Sella and of course another rifugio.
From the pass, you'll enjoy about two miles of relatively flat, rocky terrain before the final, long downhill segment begins. It's about six miles, mostly downhill, and mostly singletrack. Again, you'll have some fun running through a thick forest before joining the local roads through Selva di val Gardena (Wolkenstein in German) and the Dantercepies bubble lift.
