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.

You can walk, run, or bike them (in either direction!). You can cross the city in one day or just try a section. Get some fresh air, explore this beautiful city, and be sure to tell us about your adventure by tagging #sfcrosstowntrail.
