The Fort Vancouver National Historic Site commemorates the history of For Vancouver, the main supply depot of the British Hudson Bay Company's "Columbia Department" between 1824 and 1860. As such, the fort was central to a 700,000 mile fur trading network, which reached from Alaska to California and from the Rocky Mountains to Hawaii. The fort has also been used as the early end of the Oregon Trail and a U.S. Army Post. The community living in Fort Vancouver consisted of 35 distinct ethnicities. The site also operates the home of John McLoughlin, Chief Factor of Fort Vancouver between 1825–1845.

The site offers introductory talks at Fort Vancouver; audio tours, including a tour designed for children; self-guided tours; guided house tours; period rooms; an overnight living history program; hands-on exhibits; a children's hands-on archaeological program; Victorian handcraft, artillery, blacksmithing, carpentry, cooking, baking, and gardening demonstrations; Junior Ranger activities; and lantern tours. Reservations are required at both sites for school groups.

The Fort Verde State Historic Park commemorates Fort Verde, which was in use between 1865 to 1891, rendering it an Indian Wars period fortification. By 1865, area settlers had demanded protection from the local Native American peoples, and the Army responded by sending volunteer units—almost entirely of Mexican heritage. A number of original structures still stand. Visitors can enter three historic living quarters (those of the commanding officer, bachelors, and the doctors and surgeons), furnished in the style of the 1880s.

The park offers exhibits, period rooms, an introductory film, and a picnic area.

Completed in 1825, Fort Snelling was originally built to prevent non-U.S. citizens from making use of the Mississippi and Minnesota Rivers. After 1851, the fort served as a supply depot, training center for Union troops, and the headquarters of the Army Department of Dakota.

The fort offers a hands-on educational program; living history tours; day camps based on the pioneer stories of Laura Ingalls Wilder; blacksmithing, bread baking, tea, and hearth baking classes; outreach presentations given by costumed interpreters; lectures; and a picnic area. The website offers a virtual tour.

The James A. Garfield National Historic Site consists of Lawnfield, a historic home which James A. Garfield (1831-1881), 20th President of the United States, purchased in 1876, and an 1893 carriage house. The site presents Garfield's boyhood, education, military career, political career, and assassination. Garfield's presidential term (1881) lasted only six months, and was largely marred with political feuding over federal appointments.

The site offers an 18-minute video, exhibits, period rooms, 35-minute guided house tours, weekly children's tours, and monthly tours which cover generally inaccessible portions of the grounds. Reservations are required for the "behind the scenes" tours and for group tours. Picnics are permitted on the grounds.
