Kerið Volcanic Crater
Kerið is a striking volcanic crater lake in the Grímsnes area, known for its red volcanic slopes and vivid blue-green water. Formed around 6,500 years ago, the crater is approximately 55 meters deep, 270 meters long, and 170 meters wide. Unlike many older volcanic formations in Iceland, its slopes have relatively little vegetation, leaving the red and black volcanic rock clearly visible around the crater.
