Ptarmigan Pass

Managing agency

Pike-San Isabel NF — South Park RD

Ptarmigan Pass is a 4.2-mile out-and-back trail located in Colorado near the Pike-San Isabel National Forest, managed by the South Park Ranger District. This route offers hikers access to alpine terrain characteristic of Colorado's high country. The trail traverses through forest and open areas as it climbs toward the pass, providing views typical of the South Park area. The out-and-back format allows hikers to explore at their own pace and turn back at any point. This trail is suitable for hikers seeking a moderate day hike experience. The Pike-San Isabel National Forest setting means the trail passes through protected public lands managed for both recreation and conservation. Hikers should come prepared with adequate water and weather-appropriate gear, as conditions in the pass area can change rapidly. The trail provides access to the broader South Park Ranger District network of hiking routes. Check with the managing ranger district for current trail conditions and any seasonal closures before planning your visit.
