Forty of the palace’s 1,441 rooms are open to the public, including the private apartments of Emperor Franz Joseph and Empress Elisabeth (Sisi), as well as the exquisite 18th-century rooms of Maria-Theresa—the only female ruler of the Habsburg dynasty. The vast palace gardens are also a must-see, with a spectacular palm house made from iron and glass, a hedge maze, and a labyrinth. Visit on a skip-the-line tour to beat the crowds and benefit from the knowledge of an expert guide, or opt for a private tour for a more personalized experience. For an evening of culture and music, attend a live concert in the Schönbrunn Palace Orangery and listen to famous works by Mozart and Strauss. Or, get an overview of the city and the palace on a Vienna city tour, stopping at other highlights such as the Vienna Opera House, the Danube River, and the Kunsthistorisches Museum.
