Approximate Total Miles

Enjoy a leisurely-paced nature hike with Docent Naturalists John Seyfarth, Naureen Moon, and Katie Wilson through the lower Portola Valley trails of this popular preserve. You'll hike along the path of the famous San Andreas fault, learn a little local geology, and explore the flora and fauna around the sag pond. With luck and a good winter rainy season, you'll see some impressive fungi—for fun and photography, not foraging!—along the way. Your route will include the Meadow, Spring Ridge and Betsy Crowder trails. (Note: Families with engaged children who are attentive listeners and capable of hiking several miles are welcome on this outing with minimal elevation change.)
