Connecting the ocean fog with the sapphire waters of Lake Tahoe, State Route 20 is a major east-west highway in Northern California. SR 20 passes through a wide variety of landscapes in Northern California, including redwood forest, the largest natural lake wholly located within California (Clear Lake), the Central Valley, Gold Country and the Sierra Nevada. The highway is generally two lanes, with occasional freeway segments where it merges with U.S. 101 and SR 49.
