Ryazan's local small airport Turlatovo doesn't operate regular flights and is being used for small aircraft and training. So, the closest air terminals are Sheremetyevo, Domodedovo and Vnukovo of Moscow. From those airports Ryazan can be accessed by train, by bus, or by car/taxi.
By express train from Kazansky Rail Terminal (Казанский вокзал) in Moscow. The ride is a little less than 3 hours.
By bus from Vykhino (Выхино) bus station. The buses leave every hour.
By car / taxi
Ryazan is about 200 km from Moscow by M5 federal road. As elsewhere in Russia, the road conditions differ greatly from a 4-lines highway to narrow bottle-necks with usual traffic-jams. Depending on traffic situation the way from Moscow may take from 2 to 6 hours (beware Friday evenings and Saturday mornings in the summer).
Hiring a taxi from Moscow to Ryazan expect to pay 3,000 - 4,000 RUR for one-way journey and use only certified providers.
You can get around the city by taking a minibus, a taxi or a bus. The public transport system is represented by ancient trolleybuses which are pretty slow.
