Donkey Reservoir

For the full 13.6-mile round-trip journey, riders should expect a rewarding climb that transitions rapidly from high-desert sagebrush into a lush landscape of Ponderosa pines, quaking aspens, and Engelmann spruce. The trail is primarily a maintained dirt path, but operators will encounter technical rocky sections that require careful navigation, especially after recent rainfall when the terrain can become slick. As you ascend toward the 10,000-foot mark on Boulder Mountain, the route passes several picturesque water features including Coleman Reservoir and Round Lake. The ultimate destination, Donkey Reservoir, sits tucked beneath a dramatic volcanic rim, offering a serene atmosphere for fishing or a midday break. Along the route, keep a sharp eye out for a true local giant: the largest recorded Ponderosa pine in the Dixie National Forest, which stands as a silent sentinel over this high-country trail.
