Alpbach to Knokke-Heist: Alpine to Coastal Road Trip Guide

The 900-kilometer drive from Alpbach to Knokke-Heist crosses three countries, descending from the Kitzbühel Alps at 1,000 meters to the Belgian coast. The route primarily follows the A12 motorway through Austria, the A8/A9 in Germany, and the E40/E314 in Belgium.
