I will gladly write more - just choose the one I am yo begin with, please
Thank you, Tufta!
Such a difficult decision! Hmm...how about klify na Wolinie?
Bad luck, this is one of the few two spots I haven't visited... To be precise I was on Wyspa Wolin when I was like 7 or 8 y.o. I remember it was quite flat - so now I am surprised there are cliffs at the edges of this flatland. But the place is definetely worth visiting as there's a very nice port city nearby - Swinoujscie. More to East there's a really nice, although a bit snobbish, curort city on the Baltic - Miedzyzdroje.
Thanks Tufta! Would you please share more information about your favorites?
Puszcza Białowieska - Białowieski Primaeval Forest, North-Eastern Poland, around Białowieża (Bialowieza) for Google, Google Maps, etc, users. Famous for European Bisons living in wild.
Połoniny Caryńska i Wetlińska - the vast meadows on the mountain tops in Bieszczady Mountains, South-Eastern Poland.
Mierzeja Helska - Hel Peninsula, on the Baltic, Northern Poland, thin, very long strip of land with sea on both sides.
The first two spots are among the last places in Poland with 'dramatic' nature, wild, unspoilt and without the crowds. One may spend days there without seeing another tourist. (For Połoniny, true only out of the season). So was Hel Peninsula, but in the last 15-20 years has become too crowdy. But I still like it.
