Cosumnes River Preserve

Hiking

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 serene majesty of nature.

Wildlife

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!
