The Hanson Refuge is a tract of approximately 20,000 acres located in southwest Crawford County. Deed restrictions have designated these lands as a "game preserve", deeming them as closed to hunting and trapping.The Hanson Refuge is also home to Hanson Hills Recreational Area. Managed by the Crawford County Recreational Authority, Hanson Hills provides an extensive cross-country ski and mountain bike trail system, as well as downhill skiing and other recreational trail programs. The DNR manages the surface resources of Hanson lands; hence management efforts have to be closely coordinated to minimize impact on these areas' recreational trails and activities.
