The lagoon sits at the base of Breiðamerkurjökull glacier. Close to the sea but slightly below sea level, it is filled with huge chunks of ice that keep breaking off the glacier. As these icebergs flow towards the Atlantic, they often wash up on the lagoon's black sand beach, making for some eye-catching optics.
However, while it's a stunning spot, it's also a visual representation of climate change, as visitors can observe the dynamic melting of the Breiðamerkurjökull and Vatnajökull glaciers that feed it.
In fact, the lagoon didn't even exist 60 years ago.
Below, we've gathered some stunning pictures that will make you want to visit Jökulsárlón Lagoon.
