Central Russia is within easy striking distance of Belarus and Ukraine, both centers of ancient Kievan Rus. One of the world's most fabulous tourist destinations, Saint Petersburg, is just an overnight train ride from Moscow. Moscow is also the starting point for most journeys on the Trans-Siberian Railway, which takes travelers to destinations in the Volga Region, Urals, Siberia, and the Russian Far East, as well as non-Russian destinations such as Mongolia, Pyongyang, and Beijing.
