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. 🙂
I remember a long time ago, my dentist said that one of his friends considers mountains in Thailand as the most beautiful mountains in the world. Of course, it’s a very subjective opinion. I’m in love with Patagonia, but the point is, Thailand is not only country with islands and beaches; there are also mountains with the highest peak of 2,565 m above sea level.
