Sunset at the beach behind the Hotel del Coronado is unforgettable. Every time I look at this picture, it makes me smile. Tijuana, Mexico is only a few miles away in the other direction. Grab a snack at the hotel (parts are open to the public) and then sit on the beach and watch the world melt away. If you can, spend a night at the hotel, but ask to stay in the old section; there are views of the courtyard and a supposed ghost roaming the halls.
