Jökulsárlón ice lagoon is a popular tourist attraction in Iceland.
If you get lucky to visit it one day, please, be careful. It is easy to forget about safety when you are surrounded my such magnificent icebergs. Tourists climbing on the ice is a chronic problem there. One time, I even saw a couple taking their engagement photos on an ice float. Fortunately, the police arrived before anyone fell in the ice-cold water and got hurt.
