The city bought the land for Washington Park, located in Portland's southwest hills, in 1871. Unlike Forest Park, most of Washington Park has been landscaped to serve as a setting for its acclaimed gardens, zoo and nature-related attractions. Surrounded at its north end by the exclusive Portland Heights neighborhood, the park winds south along the ridge that stretches along the entire west side of the city. Southwest Kingston Avenue connects the Rose Garden and the Japanese Garden to Hoyt Arboretum, the World Forestry Center and the Oregon Zoo. The new extension of the city's light-rail system includes a stop at Washington Park, providing easy access from downtown; in the summer a narrow-gauge excursion train runs from the Rose Garden to the zoo. A new Children's Museum is scheduled to open next to the World Forestry Center in the former Oregon Museum of Science and Industry (OMSI) building in fall 2000.
