From the spas and resorts of Calistoga in Napa Valley to the tide pools and gorgeous shores of Carmel, you'd be surprised how much road-riding fun there is to be had along the Pacific Coast Highway. The landscape changes drastically, from the valley's lush greenery to the hills farther north in San Francisco; from the tiny towns and missions that dot the landscape to the major urban swells. You're really seeing the best California has to offer. The rides are short, so it's easy to go at your own pace and explore -- hiking, beachcombing or examining the wild urban architecture of San Francisco and Carmel -- whenever you feel the urge. The next beautiful spot is always just up around the next bend.
