If you have not traveled by Amtrak for a vacation, perhaps it is time to to give it some consideration. Many North American destination cities are easily accessible by train. Given how beautiful and interesting our country is, the trip itself can be a big part of the total enjoyment.
Of all the many great vacation destinations accessible by train, San Diego must be near the top of the list. The train runs right into the middle of town, with easy local public transportation to get you to your hotel and most of the attractions. Compared to other parts of Southern California, San Diego is actually relatively close together. You can even get around to a lot of vacation attractions by walking if you enjoy that.
San Diego is really loaded with interesting places to visit. Visiting all of the beaches, museums, historical attractions and other amusements could truly take weeks. So it is safe to assume that you can engage yourself in a week of both relaxation and activity in this harbor city. The weather in the summer is particularly appealing, with a moderate sea breeze cooling things off.
Perhaps you would like to make an even more ambitious train travel event, in which case you can take the train up the coast. It is easy to take the train from San Diego all the way to Union Station in downtown Los Angeles, with maybe ten stops in between. By doing any of the above, it would be reasonable to engage in a one- or two-week vacation without using a car.
Don’t forget that a trip by train can add several days on to the total schedule compared to flying, but if you have the right mindset the traveling can be part of the overall enjoyment of the trip.
