Home to bluecoats, bugles, and bayonets, this 1864 fort atop the Coteau des Prairies (Hills of the Prairies) is a rare reminder of the western frontier. Named for the nearby Sisseton Indian Tribe, this historic fort is now a picturesque 125-acre state park that offers an excellent introduction to the area's rich history. The Fort Sisseton Festival, held the first full weekend in June, is a rendezvous featuring cavalry, fiddlers, square dancing, draft horse pulling, tomahawk throwing, a melodrama, and other excitement.

• Walk the grounds where the officers' quarters, stone barracks, powder magazine, guard house, and other buildings remain at frontier Fort Sisseton. Enjoy historical reenactments at the Fort Sisseton Festival in June. Launch a boat onto Kettle Lake.
