Best way to travel from Vienna to Zagreb without flying? Any must stop along the way? Greatly appreciated. Teri
Hi, in my opinion, the best way to travel from Vienna to Zagreb is by train. The fast train is around 6.5 hours, and the slow train is around 8 hours. The cost is around $85. It is pretty much a straight shot south from Vienna to Zagreb basically through the countryside, so no much stop along the way that I would recommend.
