The 807-acre Leadbetter Point State Park Natural Area, 3 miles north of Oysterville, is a kind of buffer between the straggling developments of Long Beach Peninsula and a section of the Willapa National Wildlife Refuge, a band of dunes increasingly breached by Pacific waves. The narrow peninsula has four trails ranging from 1.1 to 2.9 miles that lead along the bayside wetlands or the coastal dune forest or out to the wild ocean beach. It's as good a place as any in the Northwest to watch for shorebirds.
