Bicycling

San Francisco is known for its treacherously steep hills, so it may be surprising to see so many cyclists. This is actually a great city for biking—there are ample bike lanes, it's not hard to find level ground with great scenery (especially along the water), and if you're willing to tackle a challenging uphill climb, you're often rewarded with a fabulous view—and a quick trip back down.

San Francisco Bicycle Coalition. The San Francisco Bicycle Coalition has extensive information about the policies and politics of riding and lists local events for cyclists on its website. You can download (but not print) a PDF version of the San Francisco Bike Map and Walking Guide. 1720 Market St., San Francisco, California, 94102. 415/431–2453; www.sfbike.org.
