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.

What other travelers are saying about
Kerið Crater
A beautiful volcanic crater with a vivid blue-green lake at the bottom — the colours are incredible, especially against the red volcanic rock. It’s an easy stop right off the road and worth the small entrance fee. You can walk around the rim for great views and then head down the path to the water’s edge for a different perspective. It’s not a big site, so you don’t need a lot of time here, but it’s definitely worth a visit if you’re in the area.
One of our highlights during our 2 day golden circle itinerary. You can do a walk around the crater's circumference and then walk down the steps to the lake itself. The slopes can be quite slippery, definitely wear proper footwear and walk carefully! We spent about an hour there near sunset.
Beautiful crater with a lake. You can walk down to the lake (will be slippery in wet / freezing conditions), or walk around the crater - it should be a leisurely 20-min walk. Facilities available, not a long drive from Reykjavik.
