For the first time a non-Polish speaker took part in my competition. Not only that, they got the questions right and was the first to do so. Well done @vickoly

Question 1
The question was negated, but the added difficulty hasn't stopped you from answering correctly. The colorful lakes are named: Yellow, Purple, Blue, Green. Even though the one shown at my photo looks reddish, it's called "Purple". All depends on the light and angle of viewing.

Question 2
I had to pay for a parking, but there are no entry fees for accessing the lakes.

Question 3
The summit of Mt. Skalnik is covered with trees and there are no views from it. Well, one can observe ants :-)
