Car
Having your own wheels will make your life a whole lot easier in this region, particularly if you want to travel on weekends or visit wineries, parks, and small towns that are not served by public transport. Driving in Slavonia is pleasant as roads are quiet, flat, and well-maintained. You can find excellent deals on car rentals from Zagreb, which will make up for the high tolls you'll pay on the highway from Zagreb to Osijek; if you want to bypass the toll roads, it'll add a couple of hours to your trip.
