Arrival and transportation to Vilnius center: Vilnius airport is about 6 kilometers away from Vilnius city center with the Old Town. You can reach the city using
Public Bus. You can purchase a 60-minute ticket using contactless payment at the ticket validator (in bus). Standard price – 1,25 EUR. Bus “3G” is recommended for reaching the conference venue from the airport in 30 min. See JUDU for more information about the transportation in Vilnius city, including the route planner.
Taxi, Uber or Bolt. Locals usually call a taxi by phone or use an app (BOLT, Uber, eTaxi) (airport’s address is Rodūnios kl. 10A, Vilnius 02189, Lietuva). A typical price for locals to reach the city centre from Vilnius airport is 5-8 EUR. It also depends on the time of the day and how many people request the taxi at the same time. However, if you are a foreigner, taxi drivers often ask for more. We recommend to agree on a price before getting in the car. Don’t pay more than EUR 11!
