Slovenia & Northern Croatia
From Ljubljana to Zagreb, connecting the Lake District, Piran, Istria, and Plitvice Lakes.
Connect the northern parts of both countries into a one-way route: first see Bled and Bohinj, pass the caves to Piran, cross the border to Rovinj and inland hilltop towns, then follow the Kvarner Gulf to Plitvice Lakes, ending in Zagreb. Skipping the Dalmatian Coast and the Soča Valley allows for a more relaxed driving pace. Ideal for self-drive travelers who want to see both countries in one trip and are comfortable with one-way car rental fees.
The coast and Plitvice Lakes are crowded in July and August; May to June and September to October are more comfortable.
