From the bathroom / picnic area, walk Northeast along the paved path. The path turns left and quickly becomes dirt / gravel road, labelled as the Bay Trail. Follow the trail until the large observation deck, and turn left, to follow the edge of the slough on your right. Walk the path until the framed boardwalk, then turn left, returning to the parking area. When almost to the lot, turn left, spending time to check out each of the boardwalks.
