If you find yourself headed through the Central Valley at this time of the year, a nice pit stop off Highway 5 is the San Luis National Wildlife Refuge Complex.
Migratory waterfowl enjoy the bounty of thousands of acres of wetlands fed by canals, and the refuge contains the most extensive network of pristine native grasslands, shrubs, and vernal pools that still remain within the Central Valley.
San Luis is also the largest contiguous freshwater wetlands remaining in California. No wonder the birds love it.
Bay Nature photographer Rick Lewis spent some time at San Luis recently, and sent in these pics.
