I loved this place. It's in Croatia and the place is called Plitvice Lakes.
It's a landscape with many waterfall's and stunning nature.
We went there when it was very hot, but in the park it was nice and cool.
The water is green there but very clear, you could see fish swimming.
They made paths over the water so you can look around.
It's not free though your have to pay an entrance fee.
I don't remember how much it was, so I guess that's a good sign ;)
Thank you for watching.
Have a nice day.
