New this year is a trial opening to ORV use of nearly 95 miles of forest roads located within the Camp Grayling training area in Crawford County. The roads, located on 16,000 acres of state forest lands leased from the DNR for military training, are north of County Road 612 near the city of Grayling. The forest roads will be open to the public when not in use for military training. When the area is used for training activities, roads will be gated off for public safety. Notice will be posted on the Camp Grayling Facebook page and shared on local radio stations.
