Vienna

The shoulder seasons, specifically April-May and September-October, are often considered the best times to visit Vienna. The weather is pleasant, the crowds are smaller than in peak summer, and you can enjoy outdoor activities comfortably. The Christmas markets in November and December are also a popular draw, though the city can be very crowded then.

Vienna boasts numerous world-class attractions. Some must-sees include Schönbrunn Palace and Gardens, St. Stephen's Cathedral, the Hofburg Palace (former imperial palace), the Belvedere Palace (home to Klimt's 'The Kiss'), and the Spanish Riding School. Don't forget to explore the MuseumsQuartier, a complex of museums and galleries.

When visiting Vienna, it's polite to greet people with 'Grüß Gott' (formal) or 'Servus' (informal) upon arrival. Punctuality is highly valued. Tipping is customary in restaurants (around 10%), but it's not mandatory. Be mindful of noise levels, especially in residential areas. Dress codes are generally relaxed, but dressing up a bit is appreciated when attending classical music concerts or visiting formal establishments.

Vienna has an excellent public transportation system. The U-Bahn (subway), trams, and buses are efficient and easy to use. Consider purchasing a Vienna Pass for unlimited travel and free entry to many attractions. Walking is also a great way to explore the city center, and cycling is popular, with many bike lanes available.

You must try Wiener Schnitzel (breaded and fried veal cutlet), Sachertorte (chocolate cake), and Apfelstrudel (apple strudel). Enjoy a traditional Viennese coffee at a classic coffee house like Café Central or Café Sacher. Visit a 'Heuriger' (wine tavern) in Grinzing for local wine and food.
