About
The Washington Park Arboretum, nestled in the heart of Seattle, Washington, is a breathtaking 230-acre urban oasis jointly managed by the University of Washington Botanic Gardens, Seattle Parks and Recreation, and the Arboretum Foundation. This living museum boasts one of the most diverse and important collections of woody plants in North America, with many species found nowhere else in the Pacific Northwest. It offers a unique blend of manicured gardens, natural wetlands, and serene walking trails, making it a truly special destination for nature lovers and a peaceful escape from city life.
Visitors can wander through iconic pathways like Azalea Way, renowned for its vibrant displays of azaleas, flowering cherries, dogwoods, and magnolias, particularly stunning in spring. The Pacific Connections Garden takes you on a global journey, showcasing flora from five eco-geographic regions including Cascadia, New Zealand, and China, where you can admire the vast scale of local trees like the western redcedar. The Joseph A. Witt Winter Garden delights with fragrant blooms and unique textures even in colder months, while the Arboretum's extensive collection of Japanese maples offers spectacular fall foliage. Wildlife abounds in the park's diverse habitats; keep an eye out for waterfowl such as Mallards, Wood Ducks, Gadwalls, and Canada Geese in the wetland areas, Great Blue Herons stalking the shores, and even American Beavers.
This remarkable arboretum is a free, year-round haven that continuously transforms with the seasons, offering new discoveries with each visit. Whether you're seeking a tranquil stroll, an invigorating hike, a spot for birdwatching, or a scenic backdrop for photography, the Washington Park Arboretum provides endless opportunities for exploration and connection with nature. Its combination of horticultural excellence, natural beauty, and abundant wildlife, including the lively Dark-eyed Junco and the graceful Western Sword Fern, makes it an unforgettable and restorative experience for everyone.

The history of the Washington Park Arboretum is deeply intertwined with the land's original inhabitants and subsequent urban development. Prior to European colonization, the area was home to the Duwamish people, who called it Sxwacugwit, signifying its importance as a portage route. The land was later acquired by the Puget Mill Company and became a city park in 1900. The renowned Olmsted Brothers firm played a significant role in its early design, conceptualizing Lake Washington Boulevard in 1903 and later developing a master plan for the arboretum in 1936. The Washington Park Arboretum was officially established in 1934 as a joint project between the City of Seattle and the University of Washington. During the Great Depression, Works Progress Administration (WPA) crews made substantial improvements, building infrastructure and contributing to plantings. Under the long directorship of Brian O. Mulligan from 1945 to 1972, the arboretum's plant collections flourished, and significant additions like the Joseph A. Witt Winter Garden (1949) and the Seattle Japanese Garden (1960) were developed, solidifying its status as a world-class botanical institution.
What to do here
Enjoy leisurely walks or invigorating hikes amidst diverse plant collections. Engage in birdwatching—the wetlands and waterways are excellent spots for observing Mallards, Great Blue Herons, Wood Ducks, and Canada Geese. Photography opportunities abound with seasonal blooms and varied landscapes. Consider picnicking, or for a unique adventure, rent a kayak or canoe to explore the adjacent waterways. You might spot an Eastern Gray Squirrel scampering through the trees or an Eastern Cottontail hopping in the undergrowth.
