Ft. Stevenson State Park

On the north shore of Lake Sakakawea, this park was named for a late 1800s fort that served as a supply depot for other military posts in the Dakota Territory. A replica of the original fort's guardhouse serves as an interpretive center. Boaters will find excellent facilities, including a full-service marina with fishing boat, canoe and slip rentals, concession store and boat servicing and storage. Other amenities include camping facilities, sleeping cabins, swim beach, arboretum and hiking trails.
