Spa to Zadar Road Trip Guide: Hidden Gems & Scenic Drives

The E42/A1 route from Spa to Zadar is a 1,200+ km trans-European journey that crosses five countries and three major climatic zones. Unlike the monotonous Belgian autoroute, the Croatian motorway section near the Velebit mountains is renowned for its sudden bora wind gusts that can exceed 200 km/h, making it one of the most challenging highway segments in Europe.
