Located at the centre of Vatnajökull National Park the Vatnajökull Glacier is larger than all the other glaciers in Europe combined. Short flights from a nearby airstrip carry you out over sections of this icy tundra and are the best way to experience the sheer scale of this frozen expanse.
This area is a hotspot for seismic activity and hidden beneath a layer of snow and ice are some of Iceland's most active volcanoes, including Grímsvötn, which erupted as recently as 2010.
To the east of Vatnajökull, on the edge of the park, the Breiðamerkurjökull Glacier breaks away from the main ice flow and moves towards the coast. When it hits the inland seawater lagoon, huge blocks of ice fracture from the glacial slopes creating a lake full of icebergs. This is Jökulsárlón, one of the most arresting costal lakes in on earth, where you can float among the towering ice sculptures.
