Lava fields are prevalent in the landscape of the national park, both ragged block lava and smoother ropy lava. A large proportion of them have their origin in Snaefellsjökull, either from the crater in its summit or from craters in its sides.
You will find all sorts of beautiful lava formations. Among them is Hellnahraun lava field between Arnarstapi and Hellnar in Snæfellsnes, Iceland. The source of Hellnahraun lava field is a crater near Jökulháls, now covered by the Snæfellsjökull glacier. The estimated age of the lava field is 3,900 years
