The Bay Area Ridge Trail itself is a long-distance trail, so this specific komoot route is generally designed as an out-and-back or a point-to-point journey covering a significant portion of the ridge. While some shorter segments within the parks might offer loop options, the full route as described is a substantial linear hike.
