3 Best Sights in The Willamette Valley and Wine Country, Oregon

On the campus of Oregon's oldest psychiatric hospital, this nonprofit, volunteer-run museum explores the somber history of psychiatry through artifacts such as straitjackets sewn by patients and now-regrettable treatment devices.The hospital served as the primary set for the legendary 1975 blockbuster One Flew Over the Cuckoo’s Nest, starring Jack Nicholson (which was based on a book by the same name by Oregon author Ken Kesey). A popular permanent exhibit is dedicated to the Academy Award-winning film.

Richard and Helen Rice began collecting beach agates in 1938, and over the years they developed one of the largest private mineral collections in the United States. The most popular item here is the Alma Rose rhodochrosite, a 4-inch red crystal, though the Rainbow Gallery, which showcases rocks that emit brilliant multicolor when displayed under backlights, is a close contender. The museum (in a ranch-style home) also displays petrified wood from all over the world and a gallery of Northwest minerals—including specimens of Oregon's state gem, the sunstone.

Howard Hughes's Spruce Goose, the largest plane ever built and constructed entirely of wood, is on permanent display, but if you can take your eyes off the giant you will also see more than 45 historic planes and replicas from the early years of flight and World War II, as well as the postwar and modern eras. Across the parking lot from the aviation museum is the space museum with artifacts that include a German V-2 rocket and a Titan missile, complete with silo and launch control room.
