Minnesota trails · Trout Lake Trail
A 5.0-mile out-and-back in Minnesota, with 101 ft of climbing. Reaches Lower Spring Lake and other lake destinations. Managed by the U.S. Forest Service.
The climbing leans toward the first third: 50% of the ascent falls between mile 0.0 and mile 1.7. It gives back about 130 ft along the way, so it rolls rather than climbing steadily.
