Tour of Víðgelmir Lava Tube in West Iceland

Explore Iceland’s largest cave on this guided tour of Víðgelmir lava tube in West Iceland. Travellers looking to pepper their West Iceland journey with an underground adventure should not miss this fantastic opportunity.

Víðgelmir is not only the largest cave in Iceland but one of the largest lava tubes in the world, at around 1600 metres (5249 ft) long. The lava tube is located in the Hallmundarhraun lava field on the edge of the Icelandic highlands.

On this tour, you’ll meet your friendly guide at the cave’s visitor centre. They will provide you with a helmet with a headlight before you make your way inside. After descending into the lava tube and walking through a narrow tunnel, the cave opens up into a spacious area, lit up with fixed lights.

You’ll follow your friendly guide along a walkway which will take you from one great hall to the next. You’ll see countless stalagmites, stalactites, and other strange rock formations. The vivid, rainbow-like colours of the cave’s wall will also, undoubtedly, catch your eye.

The cave is quite cold, so make sure you dress warmly. However, the cold produces thousands of icicles which all sparkle in the mounted lights. At one point in the tour, the guide will turn off all the light so you can wonder at the contrast of light and complete darkness. 

The lava tube was formed during the Viking age, around 1100 years ago. A volcano under Langjökull glacier erupted, and molten lava flowed through the nearby fields. It is located near some of West-Iceland’s top attractions including the waterfalls Hraunfossar and Barnafoss, the historical site of Reykholt, Krauma Spa, and Deildartunguhver hot spring.
