Find maps of Minnesota's state parks at the Minnesota Department of Natural Resources website. From the home page, click on Destinations, and then State Parks. Using the left sidebar, click on the By Map tab to bring up an interactive state park map of Minnesota.
Selecting a park brings up an information page, which has a link on the left side bar leading to maps for that park. Using Wild River State Park as an example, park and campground map options include an all season map, winter map and a campground map. The website also includes a USGS topography map, a recreational compass map and a satellite imagery map.
