South of Bemidji and the Mississippi headwaters, the Paul Bunyan State Forest has over 100 miles of trails and roads open to hiking and mountain biking. The trails are not marked. There are three nice loop trails worth checking out: Beaver Lakes Trail loop (6.9 miles); Thorpe Tower Loop (9 miles); Pine View Trail loop (7.6 miles).
To reach the trailhead from Akeley, head north on SR64 for 10 miles. Turn left on Forest Road 2. There is no formal parking area. Look for informal roadside parking.
Overall, Paul Bunyan State Forest is the 8th most popular hiking trail of all 31 hikes in Minnesota.
