Caves and Volcanoes

Explore the geological heritage of Western Iceland through its diverse volcanic formations. This collection features the Hallmundarhraun lava field’s massive tubes, including Víðgelmir and Surtshellir, alongside the symmetrical Eldborg crater and the iron-staircase ascent of Saxhóll.
