Alderfer/Three Sisters Park
With more than a dozen trails and connecting loops, this mountain biking haven in Evergreen is a must-ride for just about any ability. Beginners can flex their muscles on rolling hills, while the more advanced can test their mettle on technical, rocky fields. Us? We start with an arduous climb up Evergreen Mountain, zip down tree-lined singletrack on the opposite side of the hill, and pedal across the street to pick up the Ponderosa Trail's up-and-down, root-covered route back to the parking lot.
Cherry Creek Trail/Bike Path
Cruising the Cherry Creek Trail on two wheels makes for an enjoyable weekend leisure ride, and it might be the most efficient way to commute from, say, Wash Park to LoDo.
