Located on the south shore of Clear Lake, California's largest natural water lake, the city of Clearlake is roughly a 90 minute drive northwest of Sacramento and just over two hours northeast of San Francisco. Due to its prime location on the lake, Clearlake is an ideal place to stay while enjoying the abundance of outdoor activities available in the area. The nearby Anderson Marsh State Historic Park draws visitors not only to its archaeological sites that date back more than 10,000 years, but also for its great hiking, birdwatching, swimming and picnicking opportunities. Wine enthusiasts appreciate Clearlake's close proximity to a number of wineries, including those found in Clearlake Oaks and Lower Lake. Boat tours and dinner cruises are available on the Clear Lake Queen, which leaves from the nearby town of Lucerne. Every July during the Independence Day weekend, Clearlake hosts the International Worm Race, which attracts people from around the world wishing to race their pet worms.
