Arapaho-Roosevelt NF — Boulder RD

Fish Creek is a 6.7-mile loop trail located in Colorado near the Boulder Ranger District of Arapaho-Roosevelt National Forest. The route features 1,878 feet of elevation gain, making it a moderately challenging day hike suitable for hikers with solid endurance and experience on steep terrain. The loop configuration allows hikers to experience varied scenery without retracing their steps. The sustained elevation gain is distributed throughout the hike, providing consistent climbing rather than one steep section. This trail is maintained by the Arapaho-Roosevelt National Forest, Boulder Ranger District, ensuring regular upkeep of the path and trailhead facilities. The Fish Creek loop offers access to the natural landscape of the Boulder Range area of the national forest. Hikers should come prepared for mountain conditions with adequate water and weather-appropriate gear. The elevation gain suggests views and potentially higher alpine terrain as the trail climbs. The loop format makes it popular with hikers seeking a complete circuit without shuttle logistics.
