Eagles BeakEagles Beak rises above the basin

Rustic and remote, Eagles Beak is a treat reserved only for the determined peakhunter, but the rewards are many. Eagles Beak is set back high and wild just east of the Continental Divide in Rocky Mountain National Park, in a basin blessedly free of established/official trails. A long approach topped by a short but stiff scramble separates the climber from wide-open vistas across the blocky summit rocks. Much of the Wild Basin area is visible from the top of this craggy little perch. Nearby to the south, the visitor gets close-in views of resplendent Frigid Lake and Moomaw Glacier, while Longs Peak and Mount Meeker dominate the horizon to the northeast.

This peak presents a strong impression of quiet isolation. If you are up for a moderately grueling approach, are comfortable with sustained travel off maintained trails and love a good scramble, this petite little summit just could become one of your area favorites.

Colorado Rank: Eagles Beak is a soft ranked peak, which basically means there is no confirmed 300-ft variance between its summit and the lowest point of the saddle with its next highest neighbor.

As with most any mountain, you are welcome to attempt this peak any time of the year, conditions and will permitting. The long approach, however, made longer by seasonal road closures, makes Eagles Beak a good candidate to attempt in snow-free times.
