Krakow eSIM
Krakow is Poland's beautiful, affordable old capital: a vast medieval square, a castle above the river, and the soulful streets of Kazimierz. It is also the base for a visit to Auschwitz-Birkenau, which deserves care to plan. Here is how to stay online in Krakow, and get the practicalities right.
Yes to the eSIM: a Poland eSIM installed before you fly is online the moment you land at KRK, with fast, cheap, excellent 5G across the city. Two useful facts: Poland is in the EU roaming zone, so an EU 'roam like home' plan works here (UK and non-EU plans may not), and Poland uses the zloty, not the euro, so you will want some local cash. For a city break of maps and messaging, 3 to 5 GB is plenty.
Staying online in Poland's old royal capital
Krakow survived the war largely intact, so its old town is the real thing: Rynek Glowny, one of Europe's largest medieval squares, the Cloth Hall at its centre, and Wawel castle on the hill above the Vistula. A live connection is how you thread it together: booking timed entries, navigating the cobbled lanes of Kazimierz, and arranging the trips out of town that a Krakow stay is built around.
How to get connected in Krakow
Poland has fast, inexpensive, and very widely available mobile data, with strong 5G across Krakow on the networks Play, Orange, Plus, and T-Mobile. A travel eSIM roams onto them automatically, so you are online without hunting for a local SIM (which is sold with ID registration).
Choose a Poland eSIM and pay in crypto, with no card and no ID.
Scan the QR from your dashboard while you still have Wi-Fi at home.
It activates at Krakow Airport (KRK), ready for the 20-minute train to the main station.
Neighbourhoods to know in Krakow
Old-town grandeur, bohemian nightlife, or quieter and local; take your pick.
Stare Miasto (Old Town)
The walled medieval core around Rynek Glowny, ringed by the green Planty park. Central, beautiful, and where most first visits are based.
Kazimierz
The historic Jewish quarter, now the city's most atmospheric district of bars, cafes, galleries, and synagogues. Bohemian and buzzing at night.
Podgorze
Across the river, the former wartime ghetto, now a thoughtful, up-and-coming area with Schindler's Factory and good, quieter dining.
Around the station
Practical and well-connected near the main train station and Galeria Krakowska mall, handy for onward trips. Convenient rather than pretty.
Visiting Auschwitz-Birkenau, respectfully
For many, a stay in Krakow includes a visit to the Auschwitz-Birkenau Memorial and Museum at Oswiecim, about 90 minutes away. It is a place of remembrance, not a sightseeing stop, and it rewards a little planning. Entry is free but requires a booked ticket through the official museum site; in high season slots go weeks ahead, and a guided tour is required during the busiest hours. A live connection helps you hold your booking, check your reserved time, and arrange the bus or organised transport out and back.
A few quiet practicalities: dress and behave as you would at any memorial, allow around 3.5 hours on site, and note that large bags are not permitted. Photography is allowed in most areas but not all, and some spaces ask for silence. Going with respect, and being organised about tickets and timing, is the whole of it.
Other day trips from Krakow
Krakow is a superb base, and a Poland eSIM keeps working across the region, though signal can thin on rural roads and underground, so download tickets and maps first. Beyond the Auschwitz-Birkenau memorial above, three highlights:
Poland's alpine resort town about two hours south, the gateway to hiking and skiing in the Tatra Mountains.
A UNESCO-listed underground world of chapels and chambers carved entirely from salt, just outside the city.
A pretty little park of limestone cliffs, caves, and a castle, an easy green escape north of Krakow.
Getting around Krakow
The old town is compact and walkable, and beyond it trams and buses cover the city cheaply, best planned with the Jakdojade app for live routes and mobile tickets. For door-to-door, Bolt, Uber, and FREE NOW all work and are inexpensive. Everything runs on you being online, from buying a tram ticket in the app to catching a ride after dinner in Kazimierz.
Practical tips
Poland uses the zloty. Cards are widely taken, but keep some cash for kiosks, milk bars, and small stalls.
Auschwitz-Birkenau, Wawel, and Schindler's Factory sell timed tickets that go early in season.
The classic 'bar mleczny' serves hearty Polish food for very little. A great, cheap local experience.
Best time to visit Krakow
Late spring to early autumn is the sweet spot: warm, long days for the square and day trips. The bars show the average high through the year, with the ideal window highlighted; December adds famous Christmas markets in the cold.
Summer, Jun-Aug
Warm and lively, with the square in full swing and easy day trips. The peak season.
May & September
Mild, pleasant, and quieter than high summer. Arguably the nicest time to come.
Winter, Dec-Feb
Cold and often grey, but atmospheric, with Christmas markets on Rynek Glowny in December.
Shoulder, Oct-Nov
Cooling and crisp with autumn colour, thinner crowds, and better hotel prices.
