Vidgelmir Cave is one of Iceland's largest and most impressive lava caves. Located in the Hallmundarhraun lava field, it was formed thousands of years ago by flowing lava from a volcanic eruption. The cave stretches about 1,600 meters (5,249 feet) long, making it a fascinating place to explore. Visitors enter through a large opening and can see stunning rock formations inside. These include stalactites and stalagmites made from cooled lava. The walls of the cave are often colorful, with shades of red and orange created by minerals in the rock. Some parts of the cave are wide and open, while others are narrow and winding. Guided tours are available, allowing people to learn about the cave’s history and geology. Guides provide helmets and lights so visitors can safely navigate through the dark tunnels. Vidgelmir also has evidence of human activity from over a thousand years ago, including ancient artifacts. Because of its unique features, Vidgelmir Cave offers an exciting glimpse into Iceland's natural history. It's a must-see for those interested in geology or anyone curious about the wonders beneath the Earth's surface.

Great tour and our guide was full of knowledgeable lava information and fun stories with humor and a beautiful singing voice to top it off. If you come to Iceland it’s a good tour to enjoy on any day. Dress warm as it gets really cold 🥶 down there.

Amazing lava cave with parking and a bar nearby. The tour with Dominica was the highlight, she is both very funny and highly educational. The cave looks incredible and the experience is unforgettable. Just make sure to bring warm clothes since it gets quite chilly inside.

The cave is special and beautiful, impressive, one of a kind. We booked the 6pm tour. We were 6 ppl group so it felt like a private tour with time for questions and photos. The cave is VERY cold - 2 degrees (C). Rated 4 because it was a little pricey in my opinion compared to other attractions/tours in Iceland.
