The northern edge of Washington Park Arboretum includes this wonderful woodchip-paved trail around Foster Island in Lake Washington’s Union Bay, a picnic spot that once was a burial ground for Union Bay Native Americans. The waterfront trail winds through marshlands and over a series of floating bridges to smaller islands and reedy shoals.
Bird-watching is popular here, as are swimming, fishing and kayaking. It’s just too bad that the busy, elevated Hwy 520 roars above the island.
