Visit the Martin Griffin Preserve
Martin Griffin Preserve is open
Audubon Canyon Ranch eagerly welcomes you back to the Martin Griffin Preserve for fall exploring! Though we limited access in the spring nesting season to encourage the egrets’ return, we've missed our community of nature lovers and bird enthusiasts.

Visiting in General
If nesting habits allow, Audubon Canyon Ranch welcomes the public to the 1,000-acre Martin Griffin Preserve in West Marin annually from spring through mid-December.
On weekends, trained naturalists called Ranch Guides inform visitors about the nesting colony, pond life and the history of ACR.
On weekdays, we ask visitors to park, then check in at the ACR bookstore before continuing on a self-guided hike.
Created after stopping a freeway and marina development in West Marin, the preserve offers several hiking trails for exploring the canyons and their diverse ecosystems. Enjoy forests of Douglas fir, coast redwood and California bay, as well as open scrublands and breathtaking views of the Bolinas Lagoon and Pacific Ocean.
We welcome visitors to bring a picnic and then hike to Henderson Overlook for a bird's-eye peek at the courting and incubation habits of Great Egrets in a historic heronry. Or, visit the ponds and peer in to find newts and other aquatic critters. Don't miss the historic education hall, nature bookstore, birdhide and ranch yard, all of which are accessible to people with disabilities.
The ACR Nature Bookstore, located on the Martin Griffin Preserve, is open when the preserve is open to the public. Come browse our selection of field guides, local natural history books, stationary, gifts and nature-inspired toys and books for children. All proceeds from sales in the not-for-profit store help fund ACR programs.
