Completing the San Francisco Bay Trail 

A 500-mile vision connecting communities to shoreline parks, open spaces, and stunning vistas.

500-Miles of Bay Trail

A complete San Francisco Bay Trail will connect Bay Area communities to the shoreline with a continuous, accessible path around the Bay where people can walk, bike, and explore nature close to home. 

More than 350 miles of this trail already links many Bay Area communities, offering sweeping views, wildlife habitat, and access to parks and open spaces. Yet 150 miles remain unfinished; many through underserved neighborhoods where access to the Bay is most needed. Completing these trail gaps is both an opportunity and a challenge that requires partnerships, advocacy, and public investment. 

Save The Bay is building on 35 years of progress by the original Bay Trail Project to carry on this vital work. We will advocate to close gaps in the Bay Trail, maintain and protect it from sea level rise, and expand public funding. For instance, we’re working with partners such as the Bay Area Trails Collaborative, convened by the Rails-to-Trails Conservancy, to advance their seven priority Bay Trail gap projects. We will also engage local partners and residents to build a broad community of support for the trail.    

Together, we can make this 500-mile vision a lasting reality for generations to come.

Why Complete the Bay Trail? 

Over seven decades, Save The Bay has fought for increased public access to the Bay that all can enjoy. Our leaders envisioned a necklace of shoreline parks linked with trails that connect everyone to the great natural treasure in our midst. Completing the Bay Trail will improve our quality of life, access to nature and resilience to rising tides, ensuring that everyone in the Bay Area can safely enjoy the shoreline.
