Any peak-bagger worth his or her stuff sack knows that not all of the state's fourteeners are fabulous, and that there are way more thirteeners — 584 at last count — to choose from, many with more interesting routes and better views. Grizzly Peak, a failed fourteener — it lost twelve feet in the last official measurement — is currently the highest thirteener, at 13,988'. While no Grizzly route is easy, the eight-mile Couloir Classic provides the most traditional mountaineering approach, and the panoramic views of the Continental Divide and Garfield Peak make this a must-do. Just be sure to hit the right Grizzly: There are six of them over 13,000 feet in Colorado.
