This frontier fort was built during the Sioux uprisings of the 1860s and its well-preserved stone structures remain. As funds permit, the grounds are being built back as they were when the fort was occupied.
The visitor center includes interpretive displays, and a guided walking tour of the site is available. The Fort Sisseton Festival is hosted here on the first full weekend of June; the public is invited to enjoy historic events like square dancing, cavalry re-enactments, and tomahawk throwing contests.
Recreational facilities within the park include a campground, boat ramp, and a picnic area with kitchen-equipped shelter. Fort Sisseton and the visitor center are open daily from Memorial Day weekend through Labor Day; the park is open year-round.
