This stunning volcanic caldera features vibrant red and brown slopes, contrasting with azure waters, and offers scenic walking paths and diverse plant life.

Kerið Crater is a part of the larger Western Volcanic Zone – it was formed around 3,000 years ago during a volcanic eruption, leaving behind a massive caldera with a depth of about 55 m (180 ft) deep, 170 m (560 ft) wide, and 270 m (890 ft) across.

What makes Kerið so unique and captivating is the vivid colors of the rocks and surrounding vegetation. The slopes of the crater display vibrant shades of red, russet, and deep browns, creating a picturesque contrast against the azure blue water that has collected at the bottom. The changing colors of the surrounding vegetation throughout the seasons further accentuate the ever-evolving nature of this unique geological site.

Kerið is also home to a rich ecosystem, with various plant species finding a niche within its volcanic walls. Mosses, lichens, and hardy grasses cling to the rocks, creating a burst of green amidst the barren, rocky landscape.

Visitors to Kerið can walk around the crater’s perimeter, marveling at the picturesque scenery from various viewpoints.
