This trip through San Francisco’s lost sand dunes, ponds, creeks and coastline will focus on the city from the center southward, covering the Mission before heading to the bayshore at Heron’s Head Park. Learn about The Farm, community gardens, San Bruno Mountain, and more! It’s a social, historical and critical tour through the city’s ecological past and present.

Shaping San Francisco co-director Chris Carlsson conducts historical tours of San Francisco by bicycle. Bring a snack and water — we don’t stop for food! Please email us to RSVP, less than five people cancels! (And include your phone number so we can call you if rain washes out the tour!)
