The 184.5–mile Chesapeake & Ohio Canal National Historical Park preserves the history of this canal, which shipped coal, lumber, grain, and other agricultural products along the Potomac River. The canal's story intertwines with those of western expansion, transportation, engineering, the Civil War, immigration, industry, and commerce. Rangers provide a mid–19th–century living history experience, and the park also offers an option of staying overnight in one of several historic lockhouses–each with interpretive media and furnishings which simulate the living conditions of the lock keeper's family during the 1830s, Civil War, the early 1900s, or the 1950s.

The park offers two replica canal boats, drawn by mule; docents in period dress; ranger–led hikes, walks, lift lock demonstrations, power point presentations, and mule programs; canal boat tours; Junior Ranger activities; and a period room overnight experience. The website offers lesson plans, photo galleries, and a coloring page.

The Dayton Aviation Heritage National Historical Park celebrates the history and accomplishments of Wilber Wright (1867-1912), Orville Wright (1871-1948), and Paul Laurence Dunbar (1872-1906).

Sights include two interpretive centers; the Wright brothers' printing office, styled to period; a Wright brothers' bicycle shop; the brothers' third airplane, built in 1905; the Huffman Prairie Flying Field; and Dunbar's final residence. The Wright brothers are best known for creating the world's first successful airplane, while Dunbar was an African American poet celebrated for his 1896 poem "Lyrics of a Lowly Life."

The park offers two introductory films; exhibits; period rooms; guided tours of the Wright Cycle Company building, Wright-Dunbar Village, and the Huffman Prairie Flying Field; guided bicycle tours; children's programs; curriculum-based educational programs; and Junior Ranger activities. Tours of the Wright Cycle Company building are available on request only, and reservations are required for groups. Reservations are required for all school programs. The website offers an interactive timeline.
