Big Marine Park Reserve is located in the northern part Washington County. It is owned and operated by Washington County and is part of the Metropolitan Council’s Regional Park System. The park was selected as a regional facility because of its excellent natural resource features, including the St. Croix Valley/northeast ground moraine and high quality upland and wetland wildlife habitat. When completed, the park will be 1,920 acres , with 80 percent of its acreage set aside for preservation and protection. This 80 percent will eventually resemble the land as it was prior to the arrival of the settlers in the mid-1800s.
