San Diego is the 8th largest city in the entire country and the second largest in the state. It is situated in southern California and is near the Mexican border. This contributes to the rich diversity of the area and makes for a cultural blend that results in several attractions and museums and a slew of eateries serving up fusion dishes that you might not get anywhere else in the country. The temperature here is mild just about all year, making it a hot spot for beachgoers and the mild climate also made.
