The Bay Area's most gorgeous hike and ride - 
on the Ridge Trail through Marin and across the Golden Gate.

raises money to help build more Trail!

Our spring trail event is a wonderful way to enjoy a fully-supported trail adventure and aid our work to plan and build more miles of trail.

Hikers, runners, bikers and equestrians can all join the fun, with moderate to challenging options. Those on foot and wheels will be shuttled from the Presidio Main Post in San Francisco and across the iconic Golden Gate Bridge to their trailhead, and be rewarded with the enjoyment of a one-way trip, rather than an out-and-back. (10-mile hikers will hike north from the Presidio to Tennessee Valley and are shuttled back at the end of their hike.) Those on horses ride a gorgeous loop in Marin. And everyone gathers for a catered trail-side lunch!
