Travel Info

Petnica Science Center is located in western Serbia, 7 km from Valjevo (around 90 km southwest from Belgrade). If you land in Belgrade the fastest way to get to Petnica is to take a bus to Valjevo. Here we give some more details. If you ever have any doubts or questions feel free to contact the organisers.

By plane: The closest airport is Nikola Tesla Airport in Belgrade. If you lend there, you can take a bus number 72 that brings you close to the train and the bus station in the city center (for more information check the following link). The ticket for the bus is approximately 2 Euros and the bus ride takes approximately 30-40 minutes. Alternatively, you can take a cab to the city center for a typical price of around 20 Euros. Once you reach the city center, the easiest option is to take a bus from the central bus station to Valjevo.

By car: If you are coming by car from Belgrade, the fastest way is to follow the road E-763 in the direction of Lajkovac (around 60 km southwest from Belgrade) and then continue towards Valjevo. Once you are there you can ask for Petnica Science Center or just follow the signs. If you are entering Serbia by car from the west, it is faster to go straight to Valjevo. In that case please check the maps before the trip to find the easiest option.

By bus or train: You can easily reach Valjevo from the central bus station in Belgrade (make sure to go to "Lasta" platforms). The busses typically run every two hours during the day. The tickets are around 20 Euros and it takes a bit less than 2 hours to reach Valjevo. The other option is to take a train. The train station is located next to the central bus station. However, keep in mind that trains in Serbia are very slow and it will take quite longer than by bus.

Currency exchange

The Serbian currency is "Dinar" (RSD). The typical exchange rate is 1 Euro = 125 RSD. You can exchange most of the foreign currencies in many exchange offices that you can easily find. Almost all of them offer a very good prices and they are typically better than the one you can get in banks. You can also withdraw some money using the cash machines.

Lectures and other activities

Most of the lecturers are engineers. They will give detailed and in-depth lectures, mostly on the whiteboard. Make sure to have plenty of paper/notebook.

Each evening will be reserved for joint discussion, or for some activity you can arrange with lecturers during the day.

The program is rather intense and it is unlikely that you will have time to work on other private stuff during the school.

The policy of Petnica Science Center is to ask questions whenever you like (during the lecture) and you are encouraged to do so. Discussions with lecturers in the free time are also encouraged.

You will have some organized free time in Valjevo and at the nearby swimming pool. One day is reserved for a hiking trip, most probably along the Gradac river. Make sure to bring appropriate sandals or sneakers, the walk will partially go through the river and we will most certainly get wet.
