Plitvice is an amazing natural park in Croatia. Full of spectacular waterfalls and pristine water, it is a delight to walk through even if you have to share it with many thousand others 🙂
The park contains lots of well maintained pathways such as the boardwalk you can see here. The light shines through the trees and penetrates the water to reveal the colors hidden up until then. What a marvel to behold 🙂
P N C O 
it’s a pity that these places are so crowded, Pieter, because it looks so peaceful.
I guess if you go off-season or in mildy bad weather, it’s probably a lot less crowded 🙂
