Which national parks do you mean?  Sure, there&#x27;s the Golden Gate National Recreational Area, Point Reyes, San Pablo Bay National Wildlife Refuge, the smelly salt flats down by Fremont, and there&#x27;s the California Coastal National Monument.<p>Surely you don&#x27;t mean that developing the Presidio, an extremely small hilly portion of Marin, distant areas of the North and South bay, and literally the ocean would solve the Bay Area&#x27;s housing problems?<p>The nearest national parks to the Bay are Pinnacles NP (130 miles from Civic Center), Yosemite (160 miles) Lassen Volcanic NP (250 miles).<p>Admittedly, there are a ton of regional and state parks.
