Kerid is a striking volcanic crater lake on the Golden Circle route, filled with milky blue-green water amid stark black and deep red slopes. Kerid is a popular stop among tourists and locals alike.

Once believed to be an explosion crater formed 3,000 years ago. Geologists now believe it to be a collapsed magma chamber at the end of a volcanic eruption. It occurred more than 6,000 years ago. The crater is the northernmost one of the crater row called Tjarnarholar and the colourful crater is one of the several crater lakes in what is known as Iceland’s Western Volcanic Zone. This Zone includes Reykjanes peninsula and Langjokull glacier.

How deep is the Kerid crater?

Kerid is 55 meters (180 ft.) deep including the still water on the bottom. Beneath a certain level, cavities and fissures in the rock are filled with groundwater, the surface of which is called the water table.

There you can view the red and black slopes contrasting with the striking aquamarine water contributing to the otherworldly landscape.
