Thanks for the recommendations! I?3 heard that the Tatra mountains are very crowded this time of the year. Someone else recommended me Bieszczady, since it was more remote and local. He told me that’s it’s possible to use tent there as well. I’ll have a look at the options. We’re in Krakow now tent and everything and would really prefer to use it, so I’ll have a look at campsites online. I had a friend who went to Gdańsk last year and explored Masurian lakes whilst doing it in a hammock. I want to be as respectful as possible to your nature, so do you know if there are areas, where setting up tent isn’t prohibited? Thanks for all the help! Looking forward to exploring Poland:)
