As Petnica is a small village near the city of Valjevo in western Serbia, it does not have an airport, so the best way to plan a trip is through Belgrade. Once you arrive at the Belgrade Nikola Tesla Airport, you can either go by bus or train to Valjevo, or you can rent a car and go directly to Petnica.
If you travel by public transport to Valjevo, the best ways to do it is through the central bus and train stations:
Once at Valjevo, a shuttle bus will be organised to take the participants to the Science Center. All additional information will be directly provided through an e-mail once the registration is complete. And if you are planning on traveling by car… just follow the map!
