Pacific Coast Highway (California, USA)

Highway 1 from Monterey to Morro Bay through Big Sur is 90 miles of coastal road clinging to cliffs 1,000 feet above the Pacific Ocean. The Bixby Creek Bridge, built in 1932, is the most photographed bridge in California. The road twists through redwood forests, past McWay Falls (which drops directly onto the beach), and along stretches where the only thing between your tires and the ocean is a prayer. It's not the fastest road or the twistiest, but the combination of scenery, drama, and driving engagement is unmatched in North America.
