The White Pine Trail is Michigan's longest rail/trail stretching a distance of just under 100 miles on the former Grand Rapids and Indiana rail bed. The trail reaches from the north end of Grand Rapids to Cadillac. Future trails will intersect the White Pine establishing it as the backbone of the Michigan rail/trail system.

The trail is surfaced with asphalt pavement from Park Street at the north end of Grand Rapids to Sand Lake; a distance of nearly 23 miles. There is also a 13 mile section of asphalt pavement between Big Rapids and Reed City and one half mile in the village of Howard City. The northernmost mile of the trail in Cadillac is also paved. The remainder of the trail is surfaced with packed gravel or cinders with pavement or other improvements planned for the future. Riders with hybrid and mountain bikes will find the entire trail very enjoyable.
