There is fierce competition for the finest scenery on this challenging trek to Snowmass Lake: alpine lakes, rocky chasms, and 14,000-foot peaks.

Four 12,000-foot passes, classic alpine views and a rugged loop around Colorado's most-photographed peaks make this 26.5-mile backpack a Rocky Mountain epic.

This moderate 12.7-mile out-and-back climbs a glacial valley under America's most photographed peaks, where sweeping views from 12,480-foot West Maroon Pass are more than picturesque.

This 4.6-mile out-and-back climbs to a group of backcountry lakes tucked below the Continental Divide.

Hike or ride smooth singletrack on this 7.2-mile lasso-loop, which climbs gently through rich scrubland and ponderosa forest to a killer mountainside overlook.

This easy trail passes through rolling grasslands and wetlands to a scenic highpoint overlooking the Front Range. Good for winter rides and cycle-cross training.

This stiff climb to the tallest peak in the Elk Range offers unforgettable views of the Roaring Fork River and Maroon Bells-Snowmass Wilderness Area.

Traverse slippery shale and narrow sandstone ledges up this exposed pinnacle. Helmets recommended and a stomach for gut-clenching scrambles is mandatory.

Quiet rules on this mostly off-trail, 5.1-mile scramble up a boulder strewn canyon to a gnarly rocky crown with panoramic mountain views in Pike National Forest.

Thanks to only a little elevation gain, this 7-mile loop offers flatlanders great rewards (big views, wildlife, solitude) without much suffering. Pack plenty of water and sunscreen.
