Schönbrunn Palace is the number one tourist attraction in Vienna plus Austria. This is a wonderful opportunity to visit one of Europe’s finest royal residences. Tour options are a half hour for 22 rooms or an hour for 40 rooms. To avoid long lines, reserve your tickets online in advance. Also, allocate at least a couple hours to explore the expansive gardens. They are gorgeous. You will quickly understand why the former summer home of Habsburg rulers was designated as a UNESCO World Heritage Site in 1996. Schönbrunn Palace is often praised by the German word Gesamtkunstwerk meaning a total work of art.
