The town of Debrecen has a small airport with only a few international connections. Participants are more likely to arrive at the Budapest Airport. There are different ways of reaching the workshop site from the airport:
Car: Car rental is possible at the Budapest Airport. A route plan to reach ATOMKI from the airport can be found here.
Train: Take the public bus No. 200E from outside the ground level of the airport towards Budapest Kőbánya-Kispest. Bus ticket can be purchesed from the driver or from the machines at the bus stop. Get off at the 4th stop called "Ferihegy vasútállomás" (Ferihegy Railway Station). The bus timetable can be found here: from the airport and to the airport. The railway station is jut on the opposite side of the street having direct train connection to Debrecen. We recommend to use InterCity trains. A timetable can be found here. Tickets can be purchased at the station.
Shuttle bus: Probably the most convenient way is to use an airport shuttle service which provides a door-to-door transfer form the airport to your hotel. The service must be pre-booked. Booking can be done at TOSI TRANS website . The price of the transfer for two ways is 16500 HUF which must be paid in cash (Hungarian Forints) to the driver. If you prefer, the workshop organizers can also help book the transfer. Note, that the shuttle minibus collects several passangers, so some delay in departure can be expected.
