The most efficient route from Zagreb to Freiburg leaves Croatia via the A2/E59, crosses the border into Slovenia, then heads north on the Slovenian A1/E57 toward Maribor. In Austria, you join the A8/E57 near Graz and continue to the A9/E55 north through the Pyhrn Pass. Alternatively, the A10/E55 via Salzburg is slightly longer but more scenic. Both routes merge onto the German A8 near Munich, then west toward Ulm and Freiburg.

• Estimated fuel consumption: ~60 liters @ €1.60/L = €96 total.
• Tolls: Croatia vignette (€8 for 7 days), Slovenia vignette (€15 for 7 days), Austrian vignette (€9.50 for 10 days).
• Parking: Park & Ride lots in Freiburg cost about €2–4 per day.

Check traffic on the Karawanken Tunnel (often congested on weekends). Have cash or card for tolls; Austrian vignette can be purchased online or at border gas stations. The journey is well worth it for the views alone.
