Direct trains from Munich serve Innsbruck. From here on, the line follows the Inn Valley to Landeck and St. Anton, where it plunges into an 11-km (7-mile) tunnel under the Arlberg range, emerging at Langen in Vorarlberg, continuing to Bregenz, where you can change to the EuroCityExpress to Zurich (you can also change at Innsbruck for a more direct route to Zurich via Feldkirch) or go back to Munich via Bavaria. A line from Innsbruck to the south goes over the dramatic Brenner Pass (4,465 feet) into Italy.

Some of the most fascinating and memorable side trips can be made by rail. For example, two narrow-gauge lines steam out of Jenbach, one up to the Achensee, the other down to Mayrhofen in the Zillertal. From Innsbruck, the narrow-gauge Stubaitalbahn runs south to Telfes and Fulpmes.
