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.


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

Hikes will meet at the Howard Ranch Trail Head at 8:30 a.m. and will depart promptly at 9:00 a.m. Parking at Rancho Seco is $10 per vehicle and the hike is free of charge.

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.

Vernal Pools Guided Walk

Cosumnes River Preserve docents will lead the way on a trail through vernal pools, which are part of a mitigation site for SMUD. Parking at Rancho Seco is $10 per vehicle and the hike is free of charge.
