West of Cortina near Val Gardena, the Sella Ronda is a 60km mountain bike loop that is loosely based on the famous road cycling route. The well-marked Sella Ronda MTB utilizes several ski lifts resulting in over 4,380m of downhill with only 750m of ascent. Not too shabby. This clockwise loop interconnects the towns of Canazei, Val Gardena, Arabba and La Villa in Badia as it circumnavigates the Sella group of four summits (aka Sella Towers).
TIP - Since the route relies heavily on lifts, make sure to plan accordingly since some lifts may close for lunch from around noon to 2pm. Also, the lifts may close due to storms or high winds.
Overall, Sella Ronda is the 29th most popular mountain bike trail of all 45 mountain biking rides in Italy.
