In order to reach Dubna from abroad, it is recommended to book flights to/from Moscow Sheremetyevo airport since it is closer to Moscow.
From airport Sheremetyevo to Moscow
A direct aeroexpress train circulates between Sheremetyevo (Terminal E) and Belorussky Railway Station in Moscow (for details see the site https://aeroexpress.ru/en). The trip takes 35 minutes, trains circulate every 30 minutes. The ticket price is 420 rubles.
A direct express train will bring you to Paveletsky Railway Station in Moscow (for details see the web site http://www.domodedovo.ru/en/main/getting/1/aero/). The price of the ticket is 450 rubles, trip takes 40-45 min, trains circulate every 30 minutes.
You should use the subway (see the scheme of Moscow Metro http://mosmetro.ru/flash/scheme11.html) and get to the Savelovsky Railway Station from the station "Paveletskaya"or the station "Belorusskaya". The price of a metro ticket is 50 rub, no payment for the luggage. The trip (with one transfer to another metro line) will take 20-30 min. The metro is save and convenient.
Be careful with using taxi in Moscow. Use only a registered taxi which has a taxi label on the car. The prices are unpredictable and usually much higher than in West Europe. To avoid unpleasant situations, always ask the price before the trip! If the driver does not tell the approximate price in advance, it is better not to use this taxi. If you need a bill, ask about this option in advance.
Please take into account that drivers and other people in service usually speak only Russian. So, to avoid misunderstanding, we advise to write your request in advance on a piece of paper and ask for the written response.
At the Savelovsky Railway Station you can take a direct train or bus Moscow-Dubna (price is 300-400 rub). See the train (express,local) http://www.dubna.ru/95/ and bus time schedule on http://www.dubna.ru/96/7184.html .
Please take into account that Dubna has two railway stations: "Bolshaya Volga" and terminal "Dubna". Both are inside the city and have a good bus/taxi connection with any part of city. However the terminal station "Dubna" is much closer to the hotel (~400 m) where the participants will stay.
