Modern science suggests one eruption in the Snaefellsnes peninsula during historical times. The Book of Settlements mentions this eruption and explains its beginning in a legendary manner, which is not commonly acceptable nowadays. Snaefellsnes glacier lies atop an extinct volcano, the site chosen by Jules Verne for the beginning of his Journey to the Centre of the Earth.
The glacier is a magnificent sight. It rises, solitary, at the end of the peninsula, into the North Atlantic sky. Highlight of the day is to take the famous hike from Arnarstapi shore to Hellnar. On the way you will see dramatic lava formation and rich birdlife.
