Visit the Martin Griffin Preserve

Visiting in 2014

The Martin Griffin Preserve is currently closed to the public. The preserve's public opening in 2014 has been delayed due to last year's complete nesting failure of the historic Great Egret heronry. The 2014 opening date is to be determined. 

Learn more about what science, education and preserve management staff are doing to encourage the birds' return.

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 during spring and early summer, 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. 

Nature Bookstore

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.
