World Forestry Center Discovery Museum is at 4033 S.W. Canyon Rd. in Washington Park, off US 26; taking MAX Light Rail is a convenient alternative to driving. Built in dramatic Northwest Regional style architecture, the museum has been a Portland icon since 1971. Offerings include hands-on, interactive exhibits that engage visitors to learn about the forests and trees of the world. Near the museum stands “Peggy,” a restored, 42-ton steam locomotive built in 1909 for hauling massive logs.
