I have only visited each of these places for a short period of time. All of them have great weather and amazing scenery. They are truly wonderful locations. Of course LA is by far the largest and most busy but they are all large cities. If money were no issue, I would probably choose San Francisco. The scenery is really interesting with the bay, the mountains, the bridges, the redwood forests to the north and the many hills and memorable spots around the city. However, if I didnu2019t have to worry about the cost, I could probably be happy in any of these cities as long as I could find a relatively quiet spot to get away from the traffic now and then! I also spent some time in Monterrey which has a beautiful location like San Francisco, but less congestion. There are lots of nice places along the California coast besides just the biggest and most famous cities!
