"You may come in summer. for me, it is the best time to travel about the country. there are many different types of transport for travelling. You can use car, train, plain and others. it depends from you and your choice. There are so many interesting places in Russia! Kremlin, Tregyakov Gallery, Red Square in Moscow. Peterghov, Hermitage and Russian Museum in St. Petersburg! they are only 2 cities, but there are so many small towns which havd their own interesting places! You just need to choose some important cities for you and go there!
