Simply put: it's a must-do if you haven't been to San Francisco before. We were staying in Fisherman's Wharf and we rented bikes from a place that let us keep them for 24 hours. We took the day to ride around town, across the bridge and over to Sausalito. There's a nice fence between you and the traffic on the bridge so whether you're walking or riding, you feel safe. Lots of great photo ops here, with or without the fog.
