Visit the Martin Griffin Preserve
Audubon Canyon Ranch welcomes the public to the 1,000-acre Martin Griffin Preserve in West Marin from mid-March through mid-December. On weekends through mid-July, knowledgeable volunteers inform visitors about the nesting colony, pond life and the history of ACR.
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.
Bring a picnic. 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 Martin Griffin Preserve is currently open to the public during weekdays (Monday through Friday) for these hours on the following days:
December 2 through 18
Open Monday through Friday 10 a.m. to 4 p.m.
No reservations necessary. After parking, check in at the bookstore for a preserve map and a brief orientation before you start your self-guided hike.
The Martin Griffin Preserve is currently closed on the weekends. The preserve is open on the weekends from mid-March through mid-July from 10 am to 4 pm.
When you visit during this time, you are greeted by a Host who can answer your questions and provide maps of hiking trails. Trained naturalists, called Ranch Guides, are posted throughout the preserve to highlight “what’s happening” with resident flora and fauna.
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.
