Step into a world of ice when you venture into the ice cave of the Langjökull glacier. Journey below the surface of the second largest glacier in Iceland to see it from the inside. A guide shows you the natural wonders of the place, including evidence of glacial movement and stunning ice formations.

Begin your day with an early departure from Reykjavik and arrive at the Langjökull glacier to see it glistening in the morning sun. Covering 368 square miles (953 sq km), Langjökull is the second largest glacier in Iceland and is an incredible sight to behold. First view the ice cap from above as you stand atop its snowy surface, then climb into a specially modified truck to make your descent into the cave.

The truck crawls through a manmade tunnel bored into the heart of the glacier, dropping you off in an ethereal underworld cavern. Follow your expert guide as they lead you below the ice cap's surface, pointing out places where you can see the glacier's slow yet inevitable movement. Witness incredible blue-toned walls of ice and spectacular frosty formations before returning to the glacier's surface.

Reenergize with a meal at the stunning Hotel Húsafell, then take the rest of the day to explore the amazing Borgarfjördur valley with your guide. Before your tour comes to a close, pay a visit to the gorgeous Hraunfossar, a sprawling waterfall formed by rivulets streaming out of an enormous lava field.
