I'm going to Warsaw to study for quite a while, on the 29th of September. My dad will be accompanying me for the first few days (nine to be precise). He's a fan of hiking, mountains and lakes in general.
He would like to visit the Carpathian mountains and hike for a bit. I was wondering whether this was actually possible to go to a decent part of the range and hike for a bit, without it being too time consuming or leaving the country? If so, what part would it be? Time is limited, maybe two or three days at most.
To be clear, we want to travel from Warsaw to a decent bit of the Carpathian mountains inside Poland and back in 2-3 days.
