Mostar to Rust Road Trip Guide: Driving Bosnia to Germany

On the E73 south of Mostar, the road hugs the Neretva River canyon—a stretch where the asphalt literally widens from a narrow ledge to a two-lane highway as you pass the village of Buna. This 1,100-kilometer route from the historic Ottoman stone bridge in Mostar to the fairy-tale half-timbered houses of Rust, Germany, crosses six countries: Bosnia and Herzegovina, Croatia, Slovenia, Austria, possibly a corner of Hungary, and finally Germany.

Driving time without stops is about 12 hours, but you will want at least two days to appreciate the transition from Mediterranean karst to Alpine passes to Central European forests. The route demands attention to toll systems, fuel types, and border crossing quirks.

Leaving Mostar, the Neretva canyon presents sheer limestone cliffs and turquoise water. A detour to the Blagaj Tekke (monastery at the spring of the Buna River) is a quick 15-minute stop. In Croatia, Plitvice Lakes National Park is a few kilometers off the A1—a UNESCO site with cascading lakes, but plan for peak crowds. Alternative: the Krka River entrance near Šibenik has fewer visitors.

In Slovenia, the Postojna Cave complex and Predjama Castle are easily accessible. In Austria, the A2 passes near the vibrant city of Graz, a UNESCO heritage site for its Altstadt and Schlossberg. The final stretch in Germany traverses the Black Forest—stopping in Freiburg or along the B31 to see the Rhine plain. Local commerce thrives at farm stands selling cheese, wine, and schnapps. The link to how to find the best stops and hidden gems between cities offers a strategy for discovering these spots.

Road quality is excellent on main highways but deteriorates in rural Bosnia (potholes are common). Use daytime running lights. Austrian roads require winter tires from November to April. Child car seats are mandatory; in Germany children under 12 and under 150cm must use a booster seat. Pet-friendly stops include many rest areas with designated dog relief zones, especially on Austrian Raststätten.

• Fatigue stops: every 2 hours or 200 km. Recommended: rest area 'Moslavina' near Popovača, Croatia; ‘Pack’ near Sankt Andrä, Austria; ‘Rheinauen’ near Offenburg, Germany.
• Restaurants: Highway stops like ‘Dulcis’ in Croatia offer local cevapi; Austrian ‘Raststation’ has decent schnitzel.
• Hidden spots: The village of Motovun in Istria, a 30-minute detour from the A1, features truffle hunting experiences.
• Local culture: In Slovenia, stop at a ‘gostilna’ for traditional jota (bean and sauerkraut stew). In Germany, the town of Rust has a Europa-Park theme park, but less crowded activities include boat tours on the Taubergießen nature reserve.

For families, Europa-Park is a major draw, but also consider the nearby Black Forest Open-Air Museum. Pets: Many hotels in Rust accept dogs; en-route, most Austrian and German hotels allow pets for a small fee. Ensure you have an EU pet passport.

The primary route uses the A1/E73 from Mostar to Sarajevo or the quicker E73 via Kiseljak to the Croatian border at Nova Sela. Croatia uses an electronic toll system (vignette for shorter stretches or pay-per-use on the A1). Slovenia and Austria require vignettes: buy the Slovenian one online before crossing; Austrian vignettes are sold at border gas stations.

• Mostar to Split (A1): 170 km, ~2 hours, toll ~€10

Diesel is widely available; carry cash in local currencies for tolls in Bosnia (KM) and Croatia (€). Hungary uses an electronic vignette—buy at the border or online. Avoid the A2 in Croatia during summer weekends to prevent traffic jams near Karlovac.
