Best Bike Ride -- Road

Forget dodging in-line skaters on the bike paths and riding in endless circles around Cherry Creek Reservoir. You live in the Rockies, so you might as well ride in them. Head to Boulder for a scenic, challenging and expeditious -- give it an hour and a half -- ride up and back down the canyon. Not heavily trafficked and with a gentle climb (until the end, where the incline grows dramatically steeper), Left Hand Canyon is long enough for a solid sweat, but short enough to keep you interested. Additional bonuses: the stream running alongside the road that keeps you cool on the way up, the general store in Jamestown that stocks cold drinks, leaning into the gentle curves on the way down.
