Midpen Biologists believe that one or more mountain lions may live within and around Rancho San Antonio Open Space Preserve. While these lions are usually most active between dusk and dawn, sightings at Rancho San Antonio have been reported year round at all hours of the day. Please visit the Mountain Lion page on our web site to learn more about Mountain Lions, what to do if you see one, and how to stay safe while out on the trails.
