Would anyone be able to give me any ideas of interesting places to explore and have wild adventures in any of the following countries (which I and 3 friends are planning on traveling this summer):
we have already been to Budapest, Slovenski Raj national park and Prague last summer.
In Poland definitely spend some time in Krakow. The entire Old Town area is beautiful, vibrant, and FUN! The nearby Salt Mines are also amazing, you can take a local bus there for less tha a Euro.
zakopane - in Polish Tatra mountains (on the border with czech republic)
well you said you went to Prague in the Czech Repblic, but try Cesky Krumlov... its a smaller version of it and the night life is crazy!! guaranteed you'll love it there, because anyone who i've known who's been there has!
its south of Prague and anyone can tell you where it is!!
