Will my phone accidentally roam onto a Czech network?

It can near the border, in the Karkonosze and Kłodzko Valley. Set your phone to your Polish operator manually rather than automatic selection to avoid unexpected roaming onto Czech masts.

Are Wrocław's dwarf statues easy to find with a map app?

Yes. With reliable city data you can follow dedicated dwarf-hunting maps to spot many of the 300-plus bronze figures scattered around the old town, market square and Ostrów Tumski.

Good to know in Lower Silesia

The Kłodzko Valley's spa towns and border trails sit in a dead-signal pocket between Polish and Czech masts - your phone may try to roam onto a Czech network, so check settings to avoid it.

Best time to visit Lower Silesia

May to September brings warm weather for city breaks and mountain hiking; the Karkonosze slopes around Karpacz turn into a modest ski area from December to March.
