Reaching 400 Miles and Beyond

The Ridge Trail has Reached 400 Miles!

The Ridge Trail was built inch by inch AND member by member. Join us on the journey ahead to close the final gaps in Ridge Trail and make your 400-mile gift today!

Thirty-four years ago, a small band of visionaries dreamed up a world-class regional trail, one that could take you on an epic adventure around the entire Bay Area without ever stepping off the trail. Back then, accomplishing such a vision may have seemed nearly impossible, but with two-thirds of the Ridge Trail now complete, it is no longer a question of “if” it will be completed, but “when.” Click here to see a map of the Ridge Trail at 400 Miles. 


Together, we’ve built the momentum needed to connect the last 150 miles!

Since 1989, we’ve worked to fund, build, and dedicate over 400 miles of Ridge Trail. It took the efforts of countless volunteers, donors, partners and staff to get to this point. We want you to fall in love with this bold vision just like we have, and join us in connecting the last 150 miles.


Help turn the vision of a fully-connected, 550-mile Ridge Trail into a reality!



Take action today by making a 400-mile gift and becoming a Ridge Trail Member. Your donation will support our work, each and every day, to build and connect the trail, and to make the Ridge Trail more accessible to more people around the Bay Area.



Advocate for the Ridge Trail by voting for bond measures, supporting trail projects, and speaking to your local representatives. Sign up for our Trail Advocates email list and we’ll let you know when and how you can support the trail.
