While Fishermans Wharf is the least attractive/most touristy part of San Francisco it is a wonderful place to pick up a bicycle for the day and enjoy the natural delights of northern California.
You can tailor your day to suit your level of fitness, a group of four of us (two keen cyclists and two not so keen) cycled a gentle 15 miles over the space of a warm February day.
The route can take you across the very impressive Golden Gate Bridge and down a lovely fast hill into the beautiful town of Sausalito. Stop for lunch and get some great sandwiches from the deli - head on around the bays stopping sporadically to enjoy the view and feel self righteous about the exercise being taken and end up at Tiburon.
Board the Blue and Gold ferry and head back across the harbour past Alcatraz. Cycle back to the hire place, return bicycle while smiling, go for a beer - a practically perfect day.
Going to SF on a fairly tight budget, you can't beat renting a bike for a day (eg. at Blazing Saddles on Fisherman's Wharf). Very easy ride across the bridge, and down to Sausalito or Tiburon. Amazing views and a sense of achievement, all for $35 each including ferry ride back across the bay.
