Arrive in Linz, where you can have multiple choices for excursions. In the morning, step off the ship into Linz, taking in its contemporary architecture, the old city center, and the old market, and past the Mozart House, where he composed the Linz Symphony in only three days. As another alternative, pedal through Linz on an exhilarating bike tour. If you would instead fulfill your travel wish list in Salzburg, join the tour through the historic center, lovely Mirabell Gardens, Residenz Square, and the Old Market. En route to Salzburg, stop at Mondsee, home of the Basilica St. Michael, where the wedding scene from The Sound of Music was filmed. Alternatively, join a full-day excursion to the charming Czech mountain town of Cesky Krumlov, where you can stroll its cobblestone streets, marvel at the city's picturesque Baroque and Renaissance-style buildings, and tour Krumlov Castle, one of Europe's largest castle complexes.
