Purchase a 24-hour or 72-hour pass if you plan to use public transport frequently; remember to validate paper tickets in the yellow machines immediately upon your first boarding.

Avoid changing money at kiosks in the Old Town or near the main train station; use bank ATMs or look for "Honest Guide" approved exchanges like Exchange.cz.

Walk across the "Charles Bridge" at sunrise (before 7:00 AM) to experience the statues and views without the suffocating midday crowds and souvenir hawkers.

Avoid "Trdelník" (chimney cake) if you want an authentic Czech dessert; it is a modern tourist import—try a "Větrník" or "Ovocné knedlíky" instead.

Order "Pilsner Urquell" or "Kozel" at a local "Hospoda" (pub); beer is often cheaper than bottled water and is a core part of Czech social culture.

Check for "Polední menu" (lunch menu) between 11:00 AM and 2:00 PM on weekdays to get a full traditional meal for a fraction of the dinner price.

Visit the "Prague Castle" grounds in the evening after the interiors close; the courtyards remain open and beautifully lit with almost no tourists.

Head to "Naplavka" (the riverbank) on Saturday mornings for the farmers' market or on summer evenings for drinks and live music by the Vltava.

Use the "RegioJet" or "Leo Express" trains for day trips to Brno or Olomouc; they are often more modern and cheaper than the national carrier.

Download the "Mapy.cz" app for offline maps; it is developed locally and often has more detailed walking paths and "hidden" shortcuts than Google Maps.

Avoid "Dlouhá Street" late at night if you want to avoid rowdy stag parties and loud bar crawls; head to "Vinohrady" for a more sophisticated nightlife.

Visit the "Municipal House" (Obecní dům) for a coffee in the Art Nouveau cafe rather than paying for a guided tour of the building.

Avoid the "Astronomical Clock" show at the top of every hour if you are in a rush; it is a very short performance that draws massive crowds.
