Code of Ethics

As you enjoy your time at the Preserve, please keep in mind our code of ethics. Stay on the trails, leave your pets at home, keep the Preserve clean, leave no trace, keep the birds happy, and walk not ride.


Within the 50,000+ acres of the preserve, we have over 11 miles of pristine trail for you to hike. Some days you can walk for hours without spotting another human being, enjoying in your solitude the beauty of this valley landscape. Be aware of our hiking “Code of Ethics,” and check out our trail maps in the “Resources” section above to plan your trip.


The preserve is home to more than 250 bird species, more than 40 fish species, and some 400+ plant species have been verified. Keep an eye out for Greater and Lesser Sandhill Cranes, Northern Pintail, Swainson’s Hawks, and Black-necked Stilts. Within the preserve you can see for yourself the rich variety of American wildlife.

Field Trips

We welcome group visits and school field trips, and have a training program and teaching materials available for schoolteachers — or you can take one of our volunteer-guided tours!

Upcoming Events


Ducks In Scopes

Don’t forget to stop by the Cosumnes River Preserve and check out “Ducks In Scopes”, where preserve docents have a row of scopes set up, some set lower to accommodate children.

Guided Nature Walk

This is a leisurely walk on a trail that is unpaved in sections and paved in others.  Our route will take us approximately three and a half miles, but participants who do not wish to walk that far may turn around at any time.  Good family activity.

Guided Nature Walk

Join our Volunteer Naturalist as you explore part of the River Walk Trail and learn about plants, animals, and the Plains Miwoks that used to call this land home.
