How we checked licences. In Austria, selling tours is a regulated trade: a travel agency needs the Reisebüro trade and a guide the Fremdenführer trade, and every trade licence gets a number in GISA, the federal trade register. Companies that sell package trips must also insure customer money against insolvency. The GISA number is normally printed in the imprint (Impressum). We read each operator's own imprint and record the number exactly as printed; where only the trade name or a company-register number is printed, we say so in the profile. 4 of 18 publish one — shown above. Sisi Museum, Imperial Apartments & Silver Collection, Spanish Riding School, Imperial Treasury (Kunsthistorisches Museum), Rosotravel, YouOnTour Vienna, Good Vienna Tours, Wiener Spaziergänge, redandwhite.tours, Hidden Vienna Tours, Vienna Sightseeing Tours, Big Bus Tours Vienna, Anna Loves Vienna, Private Tours Vienna (Susanne Waldeck), Vienna Tour Guide (Dace Schaerf): real, reviewed operators that don't list a number publicly; we mark them unverified rather than omit them. We excluded aggregators and booking portals, which are not operators.
Left out. We list companies that sell Hofburg tours under their own name and website. Two highly rated partner guides publish no website of their own, so they appear in the bookable list above but not in this table. We left out booking platforms and city passes (they resell other companies' tours), two resellers of the official audio-guide ticket, and private guides and car-tour companies whose tours only pass the palace without a published price.
Disclosure. Direct prices and ratings are from operators' own sites and public review platforms (checked October 26, 2026). Online prices, ratings and review counts are GetYourGuide's, captured October 26, 2026; booking through those links may earn us a commission at no extra cost to you, and it never changes the order. Always confirm current price, schedule and what's included with the operator before booking. Machine-readable version (JSON)
