Overview: The Mount Sutro Loop in the Mount Sutro Open Space Reserve offers a short but immersive hiking experience right in the heart of San Francisco. Tucked away behind UCSF, this urban forest feels surprisingly secluded, with dense eucalyptus groves, winding dirt paths, and occasional city views peeking through the trees. The loop is ideal for hikers who want a quick nature escape, light exercise, and a quiet, green environment without leaving the city.
