A must-see. Best way to see San Fransisco on bike however I recommend the electric bike option as while I'm a reasonably fit 40 something its very hilly and this extra push going up hills made it for me. We took the option of the ferry back which goes round Alcatraz and saved us a half day visit as we got really close photos. Tour guide was lovely and handled all ages
