San Francisco, California

The Golden Gate Bridge, which spans San Francisco Bay, facing south from the Marin Headlands and Golden Gate Recreation Area. This is a popular place to go biking from San Francisco (you travel right across the bridge and up into the hills on the other side that make up the Marin Headlands). If you're driving up the coast from San Francisco toward Point Reyes National Seashore or Bodega Bay, this is also a wonderful stop for a photo, a quick ramble, or a picnic. You can rent bikes in San Francisco at a number of places, one of the best and most conveniently located being Avenue Cyclery, on the eastern edge of Golden Gate Park in San Francisco's Haight-Ashbury Distric
