Bay Trail Interactive Map

This street map of the Bay Area highlights sections of the Bay Trail that ring San Francisco Bay, San Pablo Bay and the rivers and estuaries that are connected to the trail. This path runs along the water from Petaluma and Napa in the north to Santa Clara and San Jose in the south.

The Bay Trail is a planned 500-mile walking and cycling path around the entire San Francisco Bay, running through all nine Bay Area counties, 47 cities, and across seven toll bridges.
