Bouverie Audubon Preserve protects oak woodland, chaparral, riparian habitat, and wildlife corridors in the hills near Glen Ellen. It is a good fit for visitors who want a quieter nature stop in Sonoma Valley rather than another winery or town walk.
Access can depend on guided walks, events, or preserve rules, so check ahead before making the trip. When open, it offers a more natural look at the valley's ecology than the developed attractions nearby.
