Will I get signal inside the castle and old town?

Mostly yes. The compact centre and castle grounds have workable 4G, so maps and bookings load fine outdoors. Signal can dip inside the castle's thick medieval walls, the tower stairwell and some deep stone cellars.

Is data reliable for a Vltava rafting or canoe trip?

Along the river through and near the town, coverage is generally good for booking and sharing photos. On longer paddles out into the wooded countryside toward Zlatá Koruna, signal can thin, so save your route offline first.

Good to know in Cesky Krumlov

Most travellers reach Český Krumlov by coach or train from Prague via České Budějovice; book RegioJet or Flixbus seats in-app, as direct buses sell out in summer, and keep data on for the walk into the car-free old town.

High-speed data, nothing to count
