Connecting the four corners of San Francisco, the Crosstown Trails run through hidden trails, public parks, shopping corridors, tiled stairways, and community gardens along the way.
The trails are the work of a small group of local volunteers who believe in building community and healthy adventuring outdoors. It connects to the city’s other urban trails, including the Bay Area Ridge Trail and the San Francisco Bay Trail.
You can walk, run, or bike them (in either direction!). You can cross the city in one day or just try a section. The trail network is not signed, but you can go to the group’s website for mobile apps and downloadable maps.
