Formed approximately 3,400 years ago, Grábrók is the largest of three craters within the same volcanic fissure. The fissure is only about 7 kilometres (4,3 miles) in length with the average thickness of 20 metres (66 feet). Both the lava field and its craters have been protected as a nature preserve since 1962. All three craters, Grábrók, Rauðbrók and Smábrók, are easily accessible from the Ring Road
