Audubon Canyon Ranch is about 3.5 miles north of Stinson Beach on Hwy 1, in the hills above the Bolinas Lagoon. A major nesting ground for great blue herons and great egrets, viewing scopes are set up on hillside blinds where you can watch these magnificent birds congregate to nest and hatch their chicks in tall redwoods. At low tide, harbor seals often doze on sand bars in the lagoon. Confirm hours, as a recent nesting failure may alter future public access.
