The California Coast Ranges are a series of mountain ranges that run parallel to the Pacific Ocean along the coast of California. Stretching from the northern part of the state down to Southern California, these ranges include notable mountains such as the Santa Cruz Mountains and the Sierra Madre Mountains. The region is characterized by its diverse ecosystems, which include coastal forests, grasslands, and chaparral. These ranges play a significant role in California's climate and ecology. They help create a barrier that influences weather patterns, leading to cooler temperatures and increased rainfall in coastal areas. The Coast Ranges are also home to various wildlife species and are important for outdoor activities like hiking and camping.
