Getaways Close to Home > Cosumnes River Preserve (CA) 
20 miles south of Sacramento,California.
The Cosumnes River Preserve is home to California’s largest remaining valley oak riparian forest, and is one of the few protected wetland habitat areas in the state. The Cosumnes River is the only free-flowing river left in California’s Central Valley. Only minutes from California’s capital, this is a critical stop on the Pacific Flyway for migrating and wintering waterfowl. Over 200 species of birds have been sighted on or near the preserve, including state-listed threatened Swainson’s hawks, greater and lesser sandhillcranes, Canada geese, and numerous ducks. The preserve includes 40,000 acres of current and potential wetlands and valley oak forests. BLM manages about 14,000 acres of the preserve.
From Sacramento, take Interstate 5 south 20 miles, and exit at Twin Cities Road. Head east 1 mile on Twin Cities Road to Franklin Boulevard, and then head south on Franklin for 2 miles to the preserve.
