Reaching 400 Miles and Beyond


The Ridge Trail began over 30 years ago when we dedicated our first miles in 1989. Now, we want you to join us as we dedicate the 400th mile!

Imagine stepping onto a trail in San José, traveling around the entire San Francisco Bay, then arriving back at that same trailhead without ever taking a step off the trail. That is the vision of the Ridge Trail: epic, conitnuous adventures for hikers, runners, mountain bikers, equestrians and nature lovers alike, accessible from your own backyard.


Since 1989, we’ve worked to fund, build, and dedicate over 390 miles of Ridge Trail. It took the efforts of countless volunteers, donors, partners and staff to get to this point. As we approach 400 miles, we want you to fall in love with this bold vision just like we have, and join us in connecting the last 150 miles.

In the early days we quickly connected trail segments and within the first 6 years, the Ridge Trail was already 200 miles long. As the “low hanging fruit” was plucked, however, progress slowed and now the more difficult trail gaps to close remain. That’s where you come in.


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