The Feldtmann Lake Trail extends 8.5 miles from Windigo to Feldtmann Lake Campground. It often serves as the first leg of a popular 29.8-mile, three-day loop that includes Feldtmann Ridge Trail, Island Mine Trail and a portion of the Greenstone Ridge Trail. The only steep climbs of this loop are over the Feldtmann and Greenstone ridges; the rest of the trek tends to be relatively level, especially Feldtmann Lake Trail. Thus most backpackers hike to Feldtmann Lake Campground first, making the final day a downhill walk along the Greenstone Ridge to Windigo.
But parts of this trail were re-routed in the early 1990s and the trek now includes an overlook 1.8 miles from Windigo, making it a popular choice for day hikers camped at Washington Creek.
