The Tatra Mountains (part of the Carpathian Mountains) is a mountain range that’s located between Slovakia and Poland.
The highest Polish peak (2499 m above sea level) belongs to Tatra
(on Slovakian side it has a bit higher peak – 2503 m).
To simplify, the central part of Poland is flat, sea is in the north, mountains are in the south part of Poland. There are two main mountain ranges: the Sudetes and Carpathian mountains; all beautiful. 🙂
You may meet jellyfish in the Baltic sea. Mostly, they are completely not harmful to people. But there is also a kind of sea jellies in the Baltic Sea that you should avoid, however it’s very unlikely to see it.
When I was a child, everyone was saying, thet “our” jellyfish are not harmful; it’s almost always the case; but it doesn’t mean 100%.
I think, we were going relatively often to the coast, when I was a child.
Somehow, I always have this image in the front of my head – sand and pink roses.
I’m sure, you can still see in Poland, many bushes with roses close to beaches.
The Wieliczka Salt Mine is one of the UNESCO World Heritage Sites. It’s a mine, so you can visit typical “things” you would expect to find in a mine. On the other hand, it’s like a museum, with many exhibitions made of salt, there is even a chapel.
