D.O. Tripp and Mathias Parkhurst built the Woodside Store in 1854. Early customers included loggers chopping down the redwoods. Dr. Tripp sold them everything from work boots and ax handles to flour and ham. When farmers settled in the area, the Woodside Store served as their county store, post office, and community center until 1909. Today, visitors can browse the shelves of the Woodside Store, restored to its 1880s appearance, and see the goods available in the mid-to-late 1800s—from canned fruit and frying pans to nails and sewing machines.

The store offers exhibits, educational programs, and occasional recreational and educational events (including living history events).

Mission Mill Museum interprets the history of the Thomas Kay Woolen Mill which produced wool products from 1889 to 1962 and represents one of Oregon's earliest and strongest industries. Mission Mill also interprets the history of Jason Lee's Methodist Mission to Oregon which settled in the Willamette Valley in 1834 before the major Oregon Trail migrations. The missionaries brought formal education, industry, and large scale agriculture and advocated for U.S. government in the Oregon country. The Museum preserves Mission houses; an Oregon Trail settler's house; a historic church; and the structures, equipment, and original water-powered turbine of the Thomas Kay Woolen Mill with related artifacts. The museum's two histories are shared with visitors through individual and group tours, interpretation, speakers, living history, children's programs, hands-on activities, and special events.

Idaho Territory was less than 10 years old when the territorial prison was built east of Boise in 1870. The penitentiary grew from a single cellhouse into a complex of several distinctive buildings surrounded by a high sandstone wall. Convicts quarried the stone from the nearby ridges and completed all the later construction. Over its century of operation, the penitentiary received more than 13,000 convicts, of whom 215 were women. Spurred in part by conditions that sparked a general riot in 1971 and an even more severe riot in 1973, the inmate population was moved to a modern penitentiary south of Boise and the Old Idaho Penitentiary was closed on December 3, 1973. Visitors begin with a video presentation recalling prison history, notorious inmates, and daily prison life. Once inside the Yard, they can imagine life in the foreboding sandstone cellhouses, see the contrasting beauty of the historic rose gardens, and view the effects of the 1973 riot. They may also visit Solitary Confinement, known as "Siberia," as well as Death Row and the Gallows.
