La Jolla, See this beach and the waterfront downtown. This is the place I grew up, San Diego! The entire area has a beautiful beaches. See the La Jolla cove, it's great for divers and swimming. It's a tourist town but very upscale and wonderful.
Take some time to explore the southern most part of the state in California's second largest city, where there are 70 miles of white sandy beaches, beautiful blue skies most of the time and a Mediterranean climate that is sure to please everyone.
