Called the Walker Trail Loop. It connects 3 trails together. You can start at several parking lots. I chose the one about a block west of Jimmy's Restaurant on Hwy 34. The eastern trail is called Shingobee Connection trail. It has some smaller hills at the south end and before that some confusing crossings of Hwy 371. Not well marked at all. The Paul Bunyan State Trail on the south end consists of steep, large, and frequent hills with only occasional minor road crossings. It includes some steep 8 percent grades for more experienced riders. The Heartland State Trail on the western end is very flat (old railroad bed). It is mostly wooded with ponds and smaller lakes that can be viewed between the trees. There is usually a port-a-potty at the parking lot in the southwest corner (end of PB Trail and start of Heartland State Trail). NOTE: The trail line showing north of this loop was an accident as I forgot to complete the ride and it was recording back to Leech Lake Resort B&B on Steamboat Loop road.
