Connecting the ocean fog with the sapphire waters of Lake Tahoe, California 20 is a major east-west state route in Northern California. California 20 passes through a wide variety of landscapes in Northern California, including redwoods, 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 California 49.
