Join the Open Space Authority in partnership with Saved By Nature for this fun and friendly walk through the beautiful oak trees of Coyote Valley. Learn all about the various oak species and their fascinating galls. What’s a gall? Come and find out! This is a gently-paced and family-friendly walk along a 4-mile loop with about 500 feet of elevation gain. Note that it may be longer than some are used to. Please bring water and a light snack. Parking is limited, and we ask that attendees carpool if possible.
