Seattle, WA - Washington Park Arboretum is a 230-acre swath that sits between Lake Washington and Downtown Seattle. It's home to some of the most diverse plant life in America, where wetlands give way to woodlands, and oak trees stand next to Japanese maples, rhododendrons, magnolias, and cacti. The crown jewel of the park is the Japanese garden, the largest of its kind outside Japan, that bursts with cherry blossoms.
