It’s summer in the San Francisco Bay Area! OK, not really. But it sure feels like it these days. The famously foggy City by the Bay and its surrounding areas can get downright chilly during the real summer months. But many of our late-autumn and early-winter days bring the kind of sunshine and clear skies that just make you want to get outdoors. Luckily, the Bay Area has thousands of acres of National Parks to help you do just that.
