Blackstone Canyon Preserve
Valleystone Dr
San Rafael, CA 94903

This secluded valley below the rugged east end of Big Rock Ridge is a great place to look for animals that are attracted to the creek. We’ll take a slow walk through the canyon to see what we can find. Total miles: 1.5. There is little elevation change. No pets (except service dogs) are allowed. Adverse weather or poor air quality may cancel. Registration is required.
