About Kerið Crater
Kerið is a stunning volcanic crater lake located in the Grímsnes area of South Iceland. It is about 3,000 years old, making it one of the younger craters in Iceland's volcanic landscape. The crater is approximately 55 meters deep, 170 meters wide, and 270 meters across.
What makes Kerið unique is its vivid colors. The water in the lake has a brilliant blue-green hue, contrasting beautifully with the red and black volcanic rock walls surrounding it. This striking color combination creates a breathtaking natural scene that draws many visitors each year.
The crater was formed when a volcano erupted and then collapsed into an empty magma chamber. Unlike many other volcanic craters, Kerið still holds water, giving it a serene and picturesque appearance. The water level varies with rainfall but generally remains consistent due to groundwater seeping through the porous rock.
Visitors can easily walk around the rim of the crater for panoramic views or take a path down to the water's edge for a closer look. The area is easily accessible by road and offers a unique glimpse into Iceland's geological past without requiring extensive hiking or climbing.
