If you're looking for something a little easier but no less beautiful, try mountain biking the Switzerland Trail in the Front Range. From Boulder you'll pedal up Boulder Canyon to Sugarloaf Road for great views of Sugarloaf Mountain. For more of a challenge, take a side trip to Bear Gulch or to the top of Bald Mountain.
Ride in the shadow of Long's Peak, through Arapahoe National Forest, and into the welcoming arms of Estes Park along Colorado's oldest scenic byway.

For an awe-inspiring road ride through some of the world's most spectacular scenery, ride Trail Ridge Road through Rocky Mountain National Park. This is a lung-busting ride along the United States' highest through highway, but for those up to the challenge, the views are worth the burn.
