The trip from Sheremetyevo International Airport to Moscow's city center takes 25 minutes by municipal bus [source: Fodor's]. Buses, trolleys and trams offer other mass transit options in Moscow, but compared to the celebrated Metro, Moscow's subway, their irregular service and often unclear stops make them less desirable, especially if you're rushing. The Metro serves 3.2 billion riders each year and trains run an average of every 50 seconds during peak times [sources: InfoPlease, Fodor's].
The Metro itself can be something of a tourist destination. Known for its collection of art pieces, many stations feature sculptures, mosaics, and stained glass pieces that depict the life of the Soviet people. The Metro is an easy way to see Moscow and popular destinations such as Red Square and the Kremlin. Pocket maps are available at newspaper kiosks, some Metro station vendors and in major hotels. A monthly pass, good for transport on most mass transit, is available at all stations [source: Fodor's]. Areas outside Moscow, such as St. Petersburg, Helsinki, Riga and Tallinn, are easily accessible by train [source: Express to Russia].
