Rapid River National Trail Professional Review and Guide
"Immense pines guard this 20-mile trail system, designed for cross-country skiing. Taking cyclists from flat wide trails to thrilling descents, the route described here follows narrow, classic skiing trails, occasionally merging with wide skating lanes.
The trail dips into a few marshy areas that require bike walking, but for the most part riders stay high and dry along a ridge with sweeping views of the surrounding forest. Although fairly well marked, it is still a rugged experience, with brushy terrain and hills chewed up by horse’s hooves. The beginning and end of the ride, however, are relaxing cruisers.
Tread: 8 miles of singletrack and wide ski trail, 0.6 mile of doubletrack."
