• Sand Dunes State Forest is located in central Sherburne County, about three miles west of Zimmerman and 5 miles north of Big Lake. The forest can be reached by taking Sherburne County five north from Big Lake, off U.S. 10, or following Sherburne County Highway 4 west from Zimmerman off U.S. 169.

• Sand Dunes has something for everyone. The 225-acre Bob Dunn Recreation Area, nestled within the forest, holds a 36-unit Ann Lake Campground and Day-Use including the Sand Dunes Horse Camp which is busy on summer weekends.

• Sand Dunes consists of oak savanna forest and prairie and 2,700 acres of pine plantation on rolling terrain. It provides beautiful areas for many recreational activities, such as horseback riding, snowmobiling, snowshoeing, hunting, swimming, panfish fishing on Ann Lake, camping and hiking.

• Over the next 30-50 years, parts of Sand Dunes State Forest will undergo changes. To better support a variety of rare plant and animal species found in this forest, areas of planted pines will gradually give way to oak savanna and prairie. Details on the changes can be found in the Sand Dunes State Forest Operational Plan and the Subsection Forest Resource Management Plan.
