The O O Denny County Park has history, hiking and old-growth trees all within the city of Kirkland. This 46-acre park is a great place to find local flora and fauna without leaving the city. See wildlife wandering through the trees, swimming in the creek and flying high in the sky. The park was also once home to the now fallen “Slyvia” — the oldest cedar tree in King County.
There are a few trails in the park with some connecting to the nearby Big Finn Hill Park. For a loop hike of about 1.2 miles, take the Lower Loop trail for 0.6 miles then head back on the 0.7 mile-Upper Loop trail.
