Day 1 — Innere Stadt: a first glimpse of old Vienna
🚶 Start at Stephansplatz by St. Stephen's Cathedral: the patterned roof, Gothic portals, and organ sounds instantly set a “Viennese” mood. Walk along Graben and Kohlmarkt to the Hofburg: old pastry shops, fur-lined display windows, and the shimmer of imperial courtyards echo the delicate clatter of trams on the Ringstrasse. Inside the complex, pick one site (for example, the Sisi Museum/Imperial Apartments) — leave the rest for other days. Finish in the Burggarten and by the Mozart Monument: sunset is especially beautiful when the domes of the Opera and the Albertina turn pink. Walking time this day is 10–15 minutes between points, unhurried.
