The East Bay Hills are a range of hills located in the eastern part of the San Francisco Bay Area in California. They stretch from the city of Richmond in the north to Fremont in the south, forming a natural barrier between the Bay and the inland valleys. The hills are part of the larger Coast Range and are known for their scenic views, diverse ecosystems, and recreational opportunities. The area is home to several parks and open spaces, including the Tilden Regional Park and the Mount Diablo State Park. These parks offer hiking, biking, and wildlife viewing, making the East Bay Hills a popular destination for outdoor enthusiasts. The hills also play a crucial role in the region's ecology, providing habitat for various plant and animal species.
