The 3,700-acre Fort Stevens State Historical Site commemorates Fort Stevens, one of three forts created to defend the harbor near the mouth of the Columbia River. The fort remained an active military site between the Civil War and World War II. The grounds also include a historic shipwreck, a gun battery and World War II command center, a museum of the fort's history, and enclosed Civil War earthworks.

The site offers exhibits, nine miles of bicycle trails, six miles of hiking trails, outdoor activities, and a picnic area. During the summer, the site also offers blacksmithing demonstrations, 90-minute tours of the gun batteries, and truck tours of the fortifications.

The Belle of Louisville site operates two vessels—the 1914 steamboat Belle of Louisville and the 1963 riverboat Spirit of Jefferson.

She is the oldest operating river steamboat. The Spirit of Jefferson has always been an excursion vessel.

The site offers cruises, curriculum-based sight-seeing excursions for students, and outreach programs for students. Field trips are available during the month of May, and are designed for kindergarten through eighth grade.

The society's museum includes three buildings. The central building is located on the grounds of the Douglas County Courthouse in Armour and originally housed the offices of auditor and register of deeds in 1902. This building was placed on the National Register of Historic Sites in 1976; and exhibits museum collections including clothing, household items, farm tools, office equipment, American Indian artifacts, military items, photographs, and other memorabilia unique to the Douglas County area. In 1981, the Society moved an 1884 country school to county property just east of the museum. It still contains some of its original furnishings along with other school items. Each spring, all second graders in Douglas County are invited to attend "School Days" in the Country School. The third building, known as the "Railroad House," was added in 1988 and is furnished and decorated in the period of the early 1900s. Furnishings include items that were already owned by the museum, as well as items donated and loaned to complete decoration.

The museums offer exhibits and tours.
