Introduction: From Dolomites to Lake Constance
The 320-kilometer drive from Bolzano (South Tyrol, Italy) to Konstanz (Baden-Württemberg, Germany) crosses the entire Alpine arc, descending from 262 meters in Bolzano to 395 meters in Konstanz, with a high point at the Reschen Pass (1,507 meters). This route follows the E45 (A22) north through the Adige Valley, then branches onto the SS40/B500 past the iconic Reschensee church tower, before hugging the Swiss-German border along Lake Constance.
Along the way, you pass through Italy, Austria (resuming the A12/E60), and Switzerland (via St. Margrethen or B500), with well-maintained highways but notable mountain segments. The average driving time without stops is 4–4.5 hours, but plan 7–9 hours to enjoy the how to find the best stops and hidden gems between cities.
A historical curiosity: the Reschensee church tower at Graun is a 14th-century bell tower that survived the 1950 dam construction that flooded the village – it remains accessible by boat in summer. This route also passes through Landsberg am Lech, where Hitler wrote Mein Kampf while imprisoned (now a memorial site).
