For many years under the Soviet Union Saratov was a closed city, meaning unless you were a citizen it was not possible to enter the city. It has only been open since 1992!
Saratov has strengths in agricultural and industrial areas. It is Southeast of Moscow and the trip by train takes about 16 hours. The most convenient train leaves in the evening and when you wake up in the morning you are there! This is a great city to see if you are interested in visiting Russia without a "tourist" atmosphere. I stayed with a Russian family. It was here I had the most opportunities to meet and mingle with the locals.
The two things that are a must is to visit Victory Park and to look upon the Volga River.
Quick Tips:
Be prepared to get a taste of "Real Russia." You will not find many tourists here as you would in St. Petersburg or Moscow. Even the streets are much different. They are a bit more bumby and not well paved.
If you are not familiar with the language I suggest at least trying to learn the alphabet. It will help in many situations. If you like cities that are not big and popular like Paris, New York, and London this is a place for you. Saratov offers both the advantages of a large city, but has the moderate prices of a small city.
Make a Russian friend. They are dedicated and loyal people both while you are in Russia and after you leave. Russians have a lot of insight to life and are some of the warmest and friendliest people I have ever gotten to know.
Best Way To Get Around:
I found the best way to get around is to take a bus. It does not cost much, just a few kopeks that you pay when you get on the bus. The front of the bus will tell you where it is going. It is very easy to understand where the bus will pick you up. Bus stops are similar to the ones seen across America.
