Bay Model Visitor Center
One of the Bay Area's most unique attractions is a model of itself. It's a giant—over an acre—hydraulic model of the San Francisco Bay–San Joaquin River Delta (Sacramento area) watershed by the U.S. Army Corps of Engineers, demonstrating how Sierra Nevada snow eventually ends up in the bay. For visitors and tourists alike, it's a fascinating place to learn about one of the most complex, diverse environmental regions in the country.
