Atlantic Peak is a 13,835-foot summit in the Tenmile Range of central Colorado, southwest of Breckenridge in the Arapaho National Forest. One of the range’s high peaks, it is often considered alongside better-known neighboring mountains. It stands close enough to be clearly visible to the northwest from the summit of Quandary Peak, a popular Colorado fourteener. Climbers also commonly pair Atlantic Peak with nearby Pacific Peak, making it part of a well-known combined hike in this section of the Tenmile Range.
