This summer being in Cluj I was scheduled to visit the Blue Lagoon but unfortunately I didn't get to do it, honestly I was expecting something else, from the pictures I saw on the internet the color of the water was beautiful (probably the pictures were taken in summer) and the place seemed more landscaped.
Anyway if I ever get through Cluj again but during the summer I will definitely visit this place to hunt down those amazing images of this place.
You brought up Geamana village, I was also there a few years ago, the water despite being contaminated had an unreal beautiful color.
In this village I spent a few hours talking to the only people who still live here and frankly their stories moved me.
Have a wonderful Sunday.
