This hike begins at the north edge of San Pablo Bay—the northern arm of San Francisco Bay—in the expansive Napa-Sonoma Marsh. The wetland habitat is located primarily between the Napa River and Sonoma Creek where they drain into San Pablo Bay. The trail follows a levee from the south end of the wildlife area through seasonal freshwater marshes and tidal salt marshes. This land was originally diked for hay and grain production. The area is now part of the former salt pond system. The Leslie Salt Company flooded the diked islands in the early 1950s for salt production.
