Start at Athens International Airport around two hours before your morning flight to Vienna International Airport, allowing extra time if you are checking bags. After landing, skip a rental car: the S7 train is the cheapest practical option into the city, taking roughly 25 minutes to Wien Mitte, while the City Airport Train takes about 16 minutes but costs more. From Wien Mitte, take the U-Bahn toward Stephansplatz; expect roughly €4–€15 depending on the airport service. Keep your bags compact, since you will be walking through central Vienna and may not have hotel check-in yet.
Begin at St. Stephen’s Cathedral, Vienna’s Gothic landmark, allowing about an hour to look inside and, if the weather is clear, climb the South Tower for city views. The cathedral is generally open to visitors from morning until early evening, though tower access can have separate hours and a small fee—roughly €6–€7. Walk west through the pedestrian streets to Hofburg Palace, passing elegant Graben and Kohlmarkt on the way. Give the imperial complex about 90 minutes; the courtyards are free to wander, while the Sisi Museum and Imperial Apartments require a ticket, usually around €19–€20. If you have luggage, check it at your accommodation or use a station locker before sightseeing.
Pause at Café Central for classic Viennese coffee and cake, budgeting approximately €10–€18 per person. It is popular and queues are common, so go slightly before the main afternoon rush; it usually operates into the evening, but check the day’s hours before setting out. From central Vienna, take the U-Bahn from Stephansplatz toward Praterstern, then walk into Prater—about 15 minutes by transit. Spend around two hours among the amusement rides, finishing with the Wiener Riesenrad, whose large enclosed cabins make it a good choice even on a cool October night. Ride tickets are typically around €13–€15, while the surrounding park is free to enter; use the well-lit main paths and head back by U-Bahn before the final services, usually around midnight.
After arriving at Salzburg Hauptbahnhof, leave your luggage at your accommodation or the station lockers, then walk about 15 minutes across the river to Mirabell Palace and Gardens. Allow roughly an hour for the formal gardens, Pegasus Fountain, and the steps and paths recognizable from The Sound of Music. The gardens are generally free and open from early morning, though some sections may close around dusk or for seasonal maintenance. From here, cross the river via Makartsteg and continue into the Old Town, allowing about 15 minutes to reach Mozart’s Birthplace on Getreidegasse. The museum is usually open daily around 9:00–17:30; admission is approximately €13–15, with student discounts worth asking about.
Spend the next 45 minutes wandering Getreidegasse, looking up at the beautifully painted façades and traditional wrought-iron shop signs rather than treating it only as a shopping street. For lunch, settle into St. Peter Stiftskulinarium, tucked beside St. Peter’s Abbey—one of Europe’s oldest restaurant sites. Expect about €18–30 per person for a modest meal, and book or arrive early if possible, as the historic dining rooms can fill quickly. Keep the pace relaxed here; Salzburg’s compact center is best enjoyed on foot.
After lunch, walk a few minutes to the Hohensalzburg Fortress and take the funicular up rather than spending energy on the steep climb; a return funicular and fortress ticket is roughly €15–18, often with student pricing. Give yourselves about two hours for the ramparts, courtyards, and panoramic views over the rooftops and surrounding mountains. Then return toward Salzburg Hauptbahnhof or Mirabellplatz and take bus 25 toward Grödig/St. Leonhard for the Untersberg Cable Car—allow approximately 35–45 minutes each way, depending on traffic. The cable car ride is the day’s real adventure: check the official timetable, weather, and final descent before leaving Salzburg, since October mountain conditions can change quickly and the service may finish around late afternoon. Wear sturdy shoes and a warm layer; even a short viewpoint walk can be windy. If visibility is poor or the cable car is closed, save the fare and enjoy the Old Town instead—do not attempt an improvised mountain hike near dusk.
If you have luggage, leave it at Salzburg Hauptbahnhof lockers or your accommodation before setting out. Take bus 25 from the station or Mirabellplatz toward Hellbrunn, usually about 25 minutes; validate or buy a Salzburg transport ticket before boarding. Start at Hellbrunn Palace and Trick Fountains, which normally opens around 9:30am in October and takes roughly two hours. The guided fountain tour is the highlight, so bring a waterproof layer—getting splashed is part of the fun. The palace grounds are also associated with The Sound of Music, and the October admission price is typically around €15–€18, subject to the 2026 tariff.
From Hellbrunn, take bus 25 back toward the centre and get off near Leopoldskron—allow about 15–20 minutes, plus a short walk. Spend around 45 minutes at the public lakeside viewpoint for the best permitted view toward Leopoldskron Palace, the exterior setting linked with the von Trapp family home. The palace itself is private, so don’t try to enter or cross restricted grounds; the reflection of the building and Untersberg on the water is what makes the stop worthwhile. If the weather is clear, this is a good place for a quick picnic snack rather than buying anything expensive nearby.
Continue by bus toward Rathaus or Herbert-von-Karajan-Platz, then walk into the Altstadt for the Mönchsberg contemporary-art walk. Take the Mönchsberg Lift beside Museum der Moderne for the fastest ascent—roughly €4–€5 one way—or walk up if you want to save money and have sturdy shoes. Allow about 90 minutes for the ridge paths, contemporary-art surroundings, and quieter viewpoints over the old town. Keep an eye on the time: October daylight fades early, and the lift and museum have seasonal schedules, generally closing in the early evening. Finish at Sternbräu in the Altstadt for lunch, where Austrian staples such as käsespätzle, schnitzel, or a vegetarian daily dish usually fit your €15–€25 budget. Ask for tap water only if you are happy to pay for it—otherwise order a small beer or the cheapest soft drink and enjoy the large traditional beer-hall atmosphere.
After lunch, collect your bags and reach Salzburg Hauptbahnhof at least 20 minutes before your Railjet. For a flight from Vienna International Airport to Athens, aim to leave Salzburg roughly 5½–6 hours before departure: the Railjet to Wien Hauptbahnhof takes about 2 hours 25 minutes, followed by the CAT or S-Bahn to the airport in around 15–25 minutes, plus a sensible connection buffer and airport check-in. Reserve seats through ÖBB, keep passports and boarding details handy, and check the platform on the day because the airport train may not leave from the same section as your Salzburg service. If your flight is late, do not risk a tight connection—an earlier Railjet is far cheaper than missing the Athens flight.
