Martin Griffin Preserve (formerly called Bolinas Lagoon Preserve) hosts one of the most studied Great Egret nesting sites on the West Coast. Each year visitors can enjoy viewing approximately 100 active nests in a grove of redwoods at the preserve.
Historically, egrets begin arriving in late March or April. During the months of the public season (mid-March through mid-July), visitors can witness various stages of the heron and egret nesting cycle including courting rituals, nest building, visible light blue eggs, chicks and first flights.
Martin Griffin Preserve features bird and wildlife viewing platforms outfitted with spotting scopes and binoculars, eight miles of hiking trails, picnic locations, a nature education-focused bookstore and natural history exhibit.
