The Habsburgs' Versailles, with gardens that alone justify the trip. Roam the grounds free.
Schonbrunn is the Habsburgs' vast baroque summer palace on the edge of Vienna, 1,441 rooms, formal gardens climbing to the Gloriette, and the childhood stage of Marie Antoinette and Franz Joseph. It's Vienna's Versailles.
Yes, but the free gardens are the highlight; the interior is a ticketed add-on.
The grounds are free; going inside or up is ticketed — book online ahead to skip the queue.
The palace interior is a timed, ticketed shuffle through a set number of rooms; it's fine, but the enormous gardens are free and, honestly, the better half of the day, so walk up to the Gloriette for the classic view back over the palace and city.
