Kerið Crater
About Kerið Crater
Kerið is a striking volcanic crater lake in the Grímsnes area of southern Iceland. The crater is about 3,000 years old and features vivid colors — deep blue-green water surrounded by steep walls of red and black volcanic rock, with moss-covered slopes. A well-maintained path circles the rim, offering views from every angle, and a staircase descends to the water's edge. At 55 meters deep and 270 meters across, it is one of the most photogenic stops along the Golden Circle extension.
🐉 Legends of Kerið Crater
Kerið Crater has been part of Icelandic folklore for generations. Local tales speak of hidden people (huldufólk) and other supernatural beings who inhabit the area. According to tradition, this place deserves respect and visitors should be mindful of the ancient spirits who call it home.
📖 History of Kerið Crater
Kerið is estimated to be about 6,500 years old and formed when a volcanic cone erupted and then collapsed inward. Unlike most Icelandic craters that formed from explosions, Kerið is believed to have formed through subsidence as the magma chamber below emptied. The water in the crater lake fluctuates with the groundwater table rather than from rainfall. In 2004, the Icelandic singer Björk performed a concert on a floating stage in the crater lake.

Lava Formations Close-Up
Look carefully at the lava formations near Kerið Crater — each tells a story of how it cooled.
Rope lava, pillow lava, and columnar basalt each formed under different conditions, creating a geological textbook in stone.
Moss & Lichens
The moss and lichen growing on the volcanic rock are some of the first life to colonize new lava fields.
Some of these organisms grow less than 1cm per year, meaning the patches you see may be decades or centuries old.
Sunset Colors
The volcanic rock takes on incredible red and gold hues during sunset.
The iron-rich minerals in the lava glow in warm light, creating a photographer's paradise.
