    The City of Salzburg

    Salzburg, located in the heart of Europe, is the capital of the federal state of the same name and the fourth largest city in Austria. The northwestern part of the city borders on the Free State of Bavaria in the Federal Republic of Germany

    The atmosphere in Salzburg is pervaded by beauty, theater and art, and not without reason Salzburg is called "The Stage of the World."

    To the city's international renown, the Salzburg Festival contributed significantly. Hugo von Hofmannsthal's Everyman has been an essential element of the Festival since 1920 and is performed every year on Cathedral Square.

    Not less has Salzburg's most famous son, W. A. Mozart, undeniably left his mark on the city: his birthplace in Getreidegasse, his residence on Markart square and his music.

    Besides the cultural experience Salzburg is enriched by a multitude of museums, galleries, sculptures and exhibitions.

    Sightseeing Tour E

    The Salzkammergut: An afternoon in the Salzkammergut Summer retreat at the famous Lake Wolfgangsee

    High nobility, artists and writers have made the Salzkammergut famous. Today, as then, it enchants with a beautiful natural landscape, places steeped in history and with its crystal-clear lakes. This half-day tour takes you across Lake Fuschl to Lake Wolfgang: St. Wolfgang was one of the most important places of pilgrimage in Europe as early as the Middle Ages.

    A touch of summer freshness!

    Fuschlsee. From the town of Salzburg there is a direct route to the nearby Fuschlsee, where the former hunting lodge of the Salzburg prince-archbishops was the location for the famous "Sissi" films. Today it houses a luxury hotel. The head quarters of Red Bull is also in Fuschl.

    Lake Wolfgang. In baroque St. Gilgen, where Wolfgang Amadeus Mozart's mother Anna Ma-ria was born, there is a change from the bus to the ship. On board a ship of the Wolfgangsee fleet - the largest inland lake fleet in Austria - you can enjoy wonderful views of the Zwölfer-horn, the Falkensteinwand and the legendary Schafberg with the cog railway.

    The shipping destination is St. Wolfgang, which is already on Upper Austrian soil: since the 14th century, the place has been the fourth most important place of pilgrimage in Europe. A spe-cial art-historical highlight is the famous Gothic winged altar by Michael Pacher. After a guided tour of the church, you can make a detour to the much sung about Hotel “Weißes Rössl” or stroll through the village with its many traditional craft shops.

    Back to Salzburg you pass Hüttenstein Castle on the deep black Krottensee and go along the legendary Mondsee.

    Sound of Music

    More than a billion people have seen the world's most successful musical adaptation "The Sound of Music" since its first broadcast in 1965. The film, starring Julie Andrews and Chris-topher Plummer, won five Oscars. Around 300,000 fans come to Salzburg every year to visit the original film locations. The original "Sound of Music" tour leads from the town of Salzburg to the famous Salzkammergut.

    Reality and myth. They really lived in Salzburg: Maria, the novice, who later became Baroness von Trapp, and her children. Their path led them from Salzburg to America while fleeing the Nazis. During their lifetime, they won people's hearts with their songs, but the film starring Julie Andrews made them legends. Today the legacy of the von Trapp family and the film "The Sound of Music" are more alive in Salzburg than ever before. During this four-hour tour, the original locations in the town of Salzburg and in the Salzkammergut are visited.

    The bus tour takes you to the original locations of "The Sound of Music". On-site the sights are visited on foot.

    The Mirabellgarten

    The Mirabell Gardens were completely redesigned under archbishop Johann Ernst von Thun in 1690. The underlying geometrical form, which is typical for the Baroque period, is still clearly recognizable. The visual orientation towards the cathedral and fortress adds to the grandeur of the gardens – simultaneously incorporating them into the overall historical ensemble of the city.

    Mirabell Palace was built in 1606 by prince-archbishop Wolf Dietrich for his beloved Salome Alt. Today, it serves as the backdrop for the most romantic weddings you could possibly imagine.

    Fortress Hohensalzburg

    Hohensalzburg Fortress is enthroned on the Festungsberg, high above the rooftops of the Baroque historical district. The biggest fully preserved castle in Central Europe, this emblem of Salzburg draws millions of tourists to our "City of Mozart" every year.

    Schloss Leopoldskron

    Picturesquely situated Schloss Leopoldskron lies just a few minutes’ walk from the Salzburg historical district, the world-famous former family seat of one of the prince-archbishops as well as an original shooting location from the movie “The Sound of Music”.


    Mozart was born in Salzburg back in 1756. The Mozart Residence on Makartplatz and the Mozart Birthplace on the Getreidegasse, both of which are now museums, remind us of his extraordinary childhood. Numerous concerts, festivals and guided tours keep the spirit of Mozart alive and well in Salzburg.
