Nestled within the Gunnison Gorge National Conservation Area and Wilderness, near Delta, Colorado, lies the captivating Cool Rock Canyon trail. This moderately challenging hike offers an immersive experience into a scenic canyon, showcasing remarkable geology and, as the name suggests, plenty of cool rocks. Spanning approximately 4 miles round trip, this trail is perfect for a half-day adventure, inviting hikers to explore its unique terrain and breathtaking views.
Getting to the trailhead is part of the adventure. While GPS directions work well, the route involves a drive east from Delta on Highway 92, followed by a turn onto either H75 Road or 2200 Road. H75 Road provides a more direct path. From the intersection of H75 and 2200 Roads, it’s about 5.3 miles on H75 Road to the South River Road split. The final 2.4 miles on South River Road descend a steep hill to the Gunnison River level, leading directly to the Cool Rock trailhead. Be aware that H75 Road is gravel, and South River Road is dirt. While accessible to most vehicles, an SUV is recommended, especially in potentially wet conditions, due to the steep descent on South River Road.

The trail is rated as moderate due to sections requiring minor scrambling over boulders. While equestrian use is permitted, these boulder fields likely restrict horses to the lower mile of the canyon. Navigating these obstacles adds a touch of adventure and physical engagement to the hike, enhancing the overall experience for those seeking a bit more challenge than an easy stroll.
