Split to Krems an der Donau Road Trip Guide

The road trip from Split to Krems an der Donau covers approximately 650 km (404 miles) and takes about 6–7 hours of pure driving time, crossing three countries: Croatia, Slovenia, and Austria. The route follows the A1 motorway north from Split to Zagreb, then continues on the A2 through Slovenia, connecting to the A9 in Austria, and finally the S5 and B3 towards Krems. A little-known fact: the stretch from Maribor to Graz on the A9 includes the Plabutsch Tunnel, one of Austria's longest road tunnels at over 10 km, and it's tolled separately via an electronic vignette system.

UNESCO World Heritage Sites Along the Way

The route passes near four UNESCO sites: Diocletian's Palace in Split (starting point), the Historic City of Trogir (short detour), Plitvice Lakes National Park (1h detour), and the Wachau Cultural Landscape around Krems. Each offers unique historical and natural value.

• Diocletian's Palace: Roman emperor's retirement palace, built around 300 AD.
• Trogir: Venetian-influenced old town on a small island.
• Plitvice Lakes: 16 terraced lakes with cascading waterfalls.
• Wachau Valley: Terraced vineyards, apricot orchards, and medieval castles.
