Discover more about Groom Creek Loop Trail #307

Groom Creek Loop Trail #307, often called the Spruce Loop, is a celebrated trail within Prescott National Forest. The nearly 9-mile loop provides a rewarding journey through the forested high country, climbing to the summit of Spruce Mountain. Despite its name, the mountain is actually populated with white firs, not spruce trees. The trail begins 6.4 miles south of Prescott on Senator Highway (Mt. Vernon Avenue), where a well-marked trailhead and ample parking await. The path is shared by hikers, mountain bikers, and horseback riders, so be mindful of fellow adventurers. Taking the trail to the right offers a longer, more gradual ascent, while the left fork presents a steeper, shorter climb. As you ascend, the trail winds through stands of Ponderosa pine and Gambel oak, with glimpses of Granite Mountain through the trees. The lower sections offer little shade, but the higher elevations provide ample cover. The trail can be rough and rocky in sections, with switchbacks and water bars adding to the challenge. At the summit, the Spruce Mountain Fire Lookout Tower offers stunning 360-degree views of the surrounding landscape. During summer months, the tower is staffed and open to visitors. The summit also features picnic tables and restrooms. Along the trail, remnants of the area's mining history and diverse wildlife add to the experience.
