Explore Austria’s capital on a tour that includes the Vienna Opera House, St. Stephen’s Cathedral, and the city’s historic center, rich in architectural marvels, Baroque castles, and lush gardens. Alternatively, pedal through Vienna on an exhilarating guided bike tour. In the afternoon, be treated to a visit to Vienna’s famous Schönbrunn Palace and Gardens. Marvel at some of the Rococo palace’s 1,441 rooms, including the Imperial Apartments, the living quarters of the Emperors, which still contain their original furnishings. Plus, delight in the lovely gardens outside with their maze, arboretum, and small zoo. Later in the day, enjoy free time to explore more of Vienna or perhaps pop into a café for a slice of rich chocolate Sacher-Torte. (B,L,D)
