Friends of the Urban Forest invites you on a free 2-hour bicycle tour of the parks, natural areas and green spaces along San Francisco’s eastern waterfront. We’ll cover 5 or 6 miles of mostly flat, paved terrain, but we’ll also ride on a few trails. Tour leader Ellyn Shea is an ISA-certified arborist. Bring your bicycle and meet at “Cupid’s Span,” the bow & arrow sculpture on the Embarcadero at Folsom St. We’ll finish at Heron’s Head Park. Please RSVP to Michele at michele@fuf.net.
