On beautiful days, it can be hard to find isolation in the canyons west of Boulder. After a stretch along the popular Lefthand Canyon, ride up James Canyon Drive, one of the lesser-ridden approaches to the Peak to Peak Highway. From Jamestown (mile 14), the road gains a lung-searing 1,600 feet in just 3.75 miles—-a stretch that holds its own against this cycling town’s other imposing climbs. Aside from the workout, this route pays off with expansive canyon views from steep switchbacks and a 2.2-mile stretch of hardpack that passes alpine meadows overshadowed by the snow-capped Indian Peaks. Stop for a snack in Ward before a descent down Lefthand Canyon that will see your cyclometer tick 40+ miles per hour, if you let it.
