View image of In the continental US, there are 70 peaks that exceed 14,000ft in height; 54 of them are in Colorado's Rocky Mountains.

Whether you decide to hike the shortest trail (just three miles to Quandary Peak near Breckenridge) or tackle the multiday routes to Longs Peak in Rocky Mountain National Park, it will never be painless.

The best known of the Rocky Mountain states, Colorado offers beautiful desert canyons, powdery ski runs and terrain that is unrivalled anywhere in the western United States.
