Diego County Page
Located in the extreme southern end of the state, the San Diego area is not only California’s southernmost major city but also the easternmost, being geographically east of San Francisco, Sacramento, Fresno, Los Angeles and even Reno, Nevada. Even though the city of San Diego is located about two hours southeast of Los Angeles, San Diego County covers a vast area, which at 4255 sq. miles (11,020 km2) is slightly larger than Delaware and Prince Edward Island combined. The Metropolitan Transit System oversees all public transport operations in the county, with various divisions and links providing a comprehensive transit network throughout the area, including cities of Chula Vista, National City and San Diego itself. In the north area of the county is the NCTD, also known as the Breeze, operating in and around Oceanside, Carlsbad and Escondido. Connecting all these cities are the Coaster train service, which runs along the Pacific coast from Oceanside to downtown San Diego; the Sprinter, a light rail service operating in conjunction with the NCTD; and the San Diego Trolley, operating in San Diego and travelling as far south as San Ysidro and the US-Mexico border, offering a quick trip to Tijuana, itself a rapidly growing city of more than one million people.
