This paved, car-free bike path stretches 8.7 miles from East Vail to the top of Vail Pass (elevation gain 1831ft), before descending 14 miles into Frisco (it's 9 miles more if you go all the way to Breckenridge). If you're only interested in the downhill, hop on a shuttle from Bike Valet and enjoy the ride back to Vail.
