Introduction: A Route Through Time and Terrain
The drive from Zagreb to Thun spans approximately 650 kilometers, crossing three countries: Croatia, Slovenia, and Switzerland. The quickest route via A1/E61, E55, and A8 takes about 6.5 hours without breaks, but hidden valleys and alpine passes reward those who linger. A unique fact: near the Croatian-Slovenian border, the A1 highway passes through the 5.8-kilometer-long Sveti Rok tunnel, which cuts directly through the Velebit mountain range—a major geological barrier since Roman times.
