Víðgelmir is around 1600 meters long has an area of 150,000 cubic meters (m³) making it one of the largest lava caves in the world. The cave is located beneath the Hallmundarhraun lava field in Iceland’s highlands.

At the base camp, your friendly caving tour guide will provide you with all the equipment that you need for the tour and give you a quick safety briefing. Then you will begin your descent into the incredible Víðgelmir lava cave, an amazing subterranean wonderland replete with sparkling colorful rock formations and sparkling icicles.

The descent begins through a narrow tunnel. This is the only tight space you’ll encounter in Víðgelmir. The cave then opens out into a spectacular hall, with incredible colorful rock formations. In winter you can see countless icicles and beautiful ice formations as well.

The walkway is lit with strategically placed lights so you can admire the incredible rock formations and the rainbow-colored walls that are truly breathtaking. At the end of the cave, your guide will turn off the lights in the cave, so you’ll be able to experience the total darkness and the huge contrast between the light and the darkness.

Your knowledgeable expert guides will tell you everything that you need to know about the lava cave and the volcanic forces that helped to create it. They will also tell you about the legends that are woven into the fabric of the area.

This lava field was formed during the Viking age, over 1100 years ago, when volcanic craters from under Langjökull glacier erupted. Formed by flowing lava moving under a hardened surface, Víðgelmir lava cave is one of Iceland’s hidden treasures that is well worth seeing.
