Visitors to Fort Totten will discover an introductory exhibit in the Fort Totten Interpretive Center in the Commissary Storehouse (Building 23). The orientation describes the military, Indian school, and historic preservation activities at Fort Totten. While strolling around the parade ground, one can explore several structures open to the public or view window exhibit panels describing the function of key buildings. Buildings painted gray with red trim display the original military color scheme. Buildings painted white with green trim show the post-1904 Indian school color scheme.
The Company Barracks/Main school (Building 14) is the home of the present-day Fort Totten Little Theater, where a local musical theater group stages productions during July. An Indian school classroom display as well as artifacts from Plummer's Mercantile Store of Minnewaukan, North Dakota, are exhibited in this building, and vending machine concessions are available.
The Hospital/School Cafeteria (Building 7) is used by the Lake Region Pioneer Daughters as a museum.
