Mercer Slough Nature Park
A fantastic park for urban hiking, Mercer Slough Nature Park — just off I-90 in Bellevue — has more than 300 acres to explore. With kids in tow, it's best to start small and begin your visit by the Environmental Education Center on the park's eastern side. Trails start just below the center and wind down the hillside to the flat wetlands where it's fun to try to spot wildlife.
Location: 1625 118th Ave. S.E., Bellevue
