Washington Park, Portland
Washington Park, located in the suburbs of Portland, is a natural park built on hills with a history of more than 100 years. The park includes the Portland Zoo, the World Forestry Center, the Portland Children's Museum (established in 1946, located in the Oregon Museum of Science and Industry (OMSI)), the Hoyt Arboretum (with a series of coast redwoods over 150 feet high, which were the first trees planted in the arboretum in 1931), the International Rose Test Garden (established in 1917, the oldest public rose test garden in the United States), and the Portland Japanese Garden (established in 1962 on the site of the former Washington Park Zoo, after which the zoo moved to its current location). In the warm sunshine of early spring, the flowers are charming, and it is really pleasant to spend a day here.
