The Cosumnes River Preserve is located on Franklin Boulevard between Thornton and Twin Cities Road. It consists of over 50,000 acres and is managed by multiple agencies. The area is made up of riparian forest, open flooded marshes, rice fields, and grasslands. There is a visitor center, 4 miles of trails, a ¼ mile long boardwalk into the marsh, and access to the Cosumnes River from a launching dock for kayaks and canoes. Much of the preserve is not open to the public unless on a guided tour. This Preserve is a major stopover for migratory birds along the Pacific-flyway.
