In one week you link Prague, Vienna, Bratislava and Budapest: four capitals, four countries, one river to tie it together, the Danube. The train does all the work, with journeys of a few hours between each city. Count two nights in Prague, two in Vienna, two in Budapest, and a stop in Bratislava on the way. One detail matters on this route: you change country, language and sometimes currency, but a single Europe eSIM keeps you online from start to finish.
Few regions pack so many capitals within reach of a train. Prague, Vienna, Bratislava and Budapest sit close together, linked by the Danube and by a dense rail network. You can have breakfast in Vienna and lunch in Bratislava the same day.
Here is a one-week itinerary that holds up, the real journey times, and the few currency and language traps to know before you go.
Why these four capitals together
They share a common history, that of the Austro-Hungarian empire, which still reads in the architecture. You find the same Viennese cafés and baroque facades from one city to the next, each with a local twist.
And yet each has its own character. Prague plays the medieval, gothic card. Vienna cultivates imperial elegance. Bratislava, the quietest, fits inside an old town you can see in half a day. Budapest ends on a high, spread across both banks of the Danube, with its thermal baths.
Vienna and Bratislava are only an hour of train apart, one of the shortest capital-to-capital rides in the world. That is what makes this circuit flow so well.
The day-by-day itinerary
Seven days is a brisk but honest pace. Here is how I split the stages so you do not spend your week in stations.
| Day | City · Country | On the programme |
|---|---|---|
| D1-2 | Prague · Czechia | Charles Bridge, castle, old town and the astronomical clock |
| D3 | Prague → Vienna · Austria | Morning train, afternoon in the historic centre |
| D4 | Vienna · Austria | Schönbrunn, the Ring, cafés and museums |
| D5 | Vienna → Bratislava → Budapest | Stop in Bratislava, arrival in Budapest for the evening |
| D6-7 | Budapest · Hungary | Parliament, Fisherman’s Bastion, Széchenyi baths |
My tip for Prague: take on Charles Bridge before 8 am or after 8 pm, the only times it is not packed. The rest of the day, head into the Malá Strana quarter, quieter, at the foot of the castle.
In Vienna, book Schönbrunn palace online with a timed slot, or you queue. Keep a late afternoon free for a proper Viennese café, a Sachertorte and the glass of water served alongside, the local tradition.
Bratislava deserves three or four hours, no more for a first time. The old town, the castle above the Danube, a Slovak lunch, and you are back on the train. In Budapest, finish with the Széchenyi baths in the evening, when the steam rises in the lamplight.
Train times between the cities
This is the backbone of the circuit. The trains are frequent, comfortable and punctual, and they drop you right in the centre. Here are the real durations to remember.
| Journey | Duration | Border |
|---|---|---|
| Prague → Vienna | ~4 h direct | Czechia → Austria |
| Vienna → Bratislava | ~1 h 07 | Austria → Slovakia |
| Bratislava → Budapest | ~2 h 30 | Slovakia → Hungary |
Book Prague to Vienna ahead for a fair price, with nine direct Railjets a day and advance fares from about 15 euros. Vienna to Bratislava you buy at the counter on the day without a worry, the ticket costs a few euros. Between Bratislava and Budapest, direct trains are more spread out, so check the times to avoid losing half a day.
A small tip for the Vienna to Bratislava leg: you can also take the fast boat down the Danube, around 75 minutes door to door. Pricier than the train, but a lovely arrival under the castle.
Currencies and budget on the ground
Here is the real trap of this circuit: you change currency twice. Vienna and Bratislava use the euro, but Prague pays in Czech koruna and Budapest in Hungarian forint.
Keep some local cash in each country for transport, tips and small shops. And steer clear of the exchange bureaus in the tourist heart of Prague and Budapest, where rates are often poor. Withdraw from a bank cash machine instead, and decline the on-screen conversion, which inflates the bill.
On the whole, Central Europe stays affordable. Prague and Budapest are clearly cheaper than Vienna, above all for meals and rooms. A good dinner is still easy to find at a gentle price away from the tourist strips.
One connection for four countries
On a circuit like this, the phone never leaves your hand: train times, the metro map in Budapest, a menu in Czech to translate, a Viennese café to book. Four countries in seven days is a lot of borders for a single week.
Rather than buy a SIM card in each country, set up a eSIM for Europe before you leave. One connection follows you from Prague to Budapest, with nothing to do at the border, and you are online the moment you step off the train.
Good to know: all four countries are in the European Union, so a European plan works there in principle. But two cases change things. If you extend towards Switzerland or the Balkans, you leave EU roaming and the charges come back. And if your home operator is not European, a travel eSIM is the only simple answer. To understand where European roaming stops, read our guide One eSIM for all of Europe.
- Book Prague to Vienna early: train fares climb fast as the date approaches.
- Two currencies to plan for: Czech koruna in Prague, forint in Budapest.
- Decline the euro conversion at the cash machine, the rate is always against you.
- Visit Charles Bridge in Prague early in the morning to have it almost to yourself.
- Book Schönbrunn online with a timed slot to skip the queue.
