Polignano a Mare to Sion: A Coastal to Alpine Road Trip

This route spans over 1,200 km from the limestone cliffs of Polignano a Mare on Italy's Adriatic coast to the alpine town of Sion in Switzerland. The drive typically takes 12–14 hours of pure highway time, but you'll want to stretch it over several days. The most direct path involves the A14, A1, and E25/E62 highways, crossing the Apennines, the Po Valley, and the Alps. A lesser-known fact: the final stretch through the Simplon Pass (SS33) descends into the Rhone Valley, offering a dramatic transition from Mediterranean scrub to glacier-fed rivers.

The route is a study in contrasts—whitewasched trulli give way to Renaissance cities, then to alpine meadows. You'll traverse three countries (Italy, possibly a short stretch through France, and Switzerland) and two climate zones. The best stops Polignano a Mare to Sion include Matera's Sassi, Bologna's porticoes, and the medieval village of Gruyères. Is it worth driving Polignano a Mare to Sion?
