All You Need to Know.

When you’ve decided to go the distance on the Ridge Trail.

Weeks or months spent in nature is good for body and soul. It’s a magical experience. You’ll meet countless wonderful people and join them in the Ridge Trail community. Breathtaking 360 degree panoramas are the rule…and on the Ridge Trail you are free to choose your mode of adventure whether it’s backpacking, bikepacking, horsepacking, or thru-hiking. Some choose to complete it in one sprint and others enjoy exploring the Ridge Trail by section. The Ridge Trail runs through all of the Bay Area’s nine counties: Alameda, Contra Costa, Marin, Napa, San Francisco, Santa Clara, San Mateo, Solano, Sonoma, as well as Santa Cruz. As of Fall 2019, you’ll be able to access the Ridge Trail by BART.

What better way to discover your local wild?
