A small town inside a river loop, walkable end to end, with signal that follows the contours.
Publié: 21 septembre 2026Dernière mise à jour: 21 septembre 2026
There is no airport and no direct train. Most arrivals are coaches from Prague or Vienna into the Český Krumlov bus station by the supermarket; rail passengers change at České Budějovice and land at a small station on the hill above town, a twenty-minute walk down. If you drive, know that the old town is closed to cars and you will be leaving it in an outer car park such as Jelenka or Horní Brána. Turn the line on before you board or before you leave the car — once you are in the lanes there are no street names to ask about.

Most people give Český Krumlov one or two nights after Prague, or stop here on the way down to Austria. The old town sits inside an almost-complete loop of the Vltava, which means everything is a climb or a descent and every distance walks longer than it looks. The visitors are day-trippers, photographers and, in summer, people floating down the river on rafts. Connectivity here has less to do with being central than with whether you are up on the castle terrace or down at the waterline.

Up on the castle terrace and the tower walk you can see the whole valley, and that is where the phone is happiest. Down at the waterline and under the stone bridges you are at the bottom of a gorge, and it feels like it: slower, and with your position drifting. The riverside road out towards the Šumava forest turns properly wooded faster than you expect, and the rafting and canoe stretches through the deep bends drop out at intervals. In a sub-zero winter the battery falls away much faster than usual, so carry a power bank even in a town this size.
A day here costs less data than a big city, roughly 400MB to 900MB, because the walking is short and there is no transport app to keep checking. What actually eats it is photographs and short video from the viewpoints above the river bend, shot several times over while you wait for the light. Spend the day on a raft and upload it all at night and about 1.5GB is a fair guess — but budget battery more carefully than data.
Czechia plans work country-wide, Český Krumlov included.

More than you would guess: the old lanes carry almost no street names, and plenty of guesthouses sit down passages you will not find unaided. Castle tour slots and raft departures are checked on a phone too. Hotel wifi is usually fine, but it stops at the front door.
A properly sealed dry bag, tied to the boat — capsizing at the low weirs genuinely happens. Signal comes and goes in the deep bends, so tell your guesthouse or your friends in advance which landing you are aiming for and roughly when, rather than relying on messages from the water.
It depends on whether what you bought lists both countries, so read the covered-destination list before you set off. Near the border a phone often flips back and forth between networks on either side for a while; that is normal border behaviour, not a fault with your line.
Sub-zero air temporarily cuts how much current a battery can deliver; that is temperature, not reception. Keep the phone in an inside pocket close to you, drop the screen brightness, and carry a charged power bank. Once the phone warms up, some of the vanished percentage usually comes back on its own.
