Kotor to Mariazell Road Trip Guide: Scenic Drive through Balkans & Alps

The drive from Kotor to Mariazell spans approximately 800 kilometers crossing Montenegro, Bosnia and Herzegovina, Croatia, Slovenia, and Austria. Along the way, you'll traverse the Dinaric Alps, the Pannonian Basin, and the foothills of the Eastern Alps. This route is known for its dramatic shifts in landscape, from the deep blue Bay of Kotor to the lush green forests of Styria. The journey typically takes 9 to 10 hours of pure driving, but with stops, plan for at least two days. In 1908, the first automobile road connecting the Bay of Kotor to the interior was completed, a testament to the region's challenging terrain.

The route primarily uses highways: E65/E80 from Kotor to Sarajevo, then E73 to Doboj, and A1/A2 in Croatia and Slovenia, finally Austrian A2 and B20. Toll roads exist in Croatia, Slovenia, and Austria. Purchase vignettes for Slovenia and Austria. Fuel stations are frequent along highways, but in Bosnia, fill up in larger towns. The average fuel cost is around €1.30 per liter in Croatia, €1.20 in Bosnia, and €1.40 in Austria.
