Estero Americano Coast Preserve

Estero Americano Coast Preserve is a nature preserve owned and managed by The Wildlands Conservancy, a nonprofit land conservancy. Located along the Pacific Ocean and the Estero Americano Estuary in Sonoma County, California, the preserve offers scenic views of the estuary's mouth and surrounding hills. It is currently closed to the public. The preserve is part of the organization's collection of natural lands; more preserves can be found in the list of preserves.

Several conservation groups collaborated on purchasing Estero Ranch. There has been active land preservation along the Sonoma Coast over the years. Sonoma County supervisors approved updated coastal protections.
