Bay Area

The San Francisco Bay Area is one of the nation's most important biodiversity hotspots, with every corner feeling like a different world. Thanks to the region's strong environmentalist movement, these lands are public and yours to explore, and thanks to the region's strong transit network, you can get there without having to get in a car.
