At 14,440 feet, Mount Elbert is the highest peak in Colorado and the whole Rocky Mountains. Its main trail is a straightforward hike.

Why go: Hike to the top of the Rockies in a day on a moderate trail. Watch sunrise light up the Sawatch Range, then get a meal in Leadville.

The view from the summit inspired Katharine Lee Bates to write "America the Beautiful" in 1893. You can reach the top on foot, by car, or on the world's highest cog railway.

Why go: Hike the 13-mile Barr Trail, drive to the summit, or ride the cog railway. Try the high-altitude donuts at the summit visitor center.

Longs Peak is the only peak over 14,000 feet in Rocky Mountain National Park. More than 50 people have died trying to climb it.

A cross of snow forms in a 1,500-foot gully on the mountain. It's easiest to see in early summer, before the snow melts.

Capitol Peak is widely considered the hardest and most dangerous of Colorado's 14,000-foot peaks. Its Knife Edge is a narrow ridge with 2,000-foot drops on both sides.

Why go: Climb the most technical standard route among Colorado's 14,000-foot peaks. On the Knife Edge, you straddle a fin of rock with big drops on both sides.

Quandary is one of Colorado's most popular 14,000-foot peaks, with a well-kept trail and only 3,450 feet of elevation gain. Its name comes from miners who couldn't identify a blue mineral they found here.
