These tours offer a rare opportunity to explore the mysterious underground world of lava tubes, showcasing Iceland's volcanic landscape from a different perspective.

What's it like to go inside a lava cave?

Exploring a lava cave is a fantastic experience for anyone interested in geology and volcanic activity. The caves are usually dark and cold — they can feel a bit spooky, as the unique rock formations create an almost otherworldly atmosphere.
Visiting with an experienced guide is the best way to see a lava cave, as the guides will provide the safety equipment you need.

How do lava caves in Iceland form?

Icelandic lava caves form when a river of lava cools from the outside, forming a rock-crust surrounding still flowing lava. When this lava has flushed out, all that is left is the tube that cooled around it. Eventually, experts discover this tube in the field and once it is deemed safe, visitors are invited to explore.

Will there be any natural light inside the caves during my tour?

Most lava caves in Iceland will be pitch black as soon as you are away from the entrance, although some are fitted with light installations to help you navigate your way within the cave. Your tour operator will provide you with a helmet equipped with a torch to increase visibility when it gets dark.

Are there walking paths inside the lava caves?

Some lava caves, like Raufarholshellir and Vidgelmir, have walking paths, but others don’t. If you visit a cave without a walking path, you’ll walk over rocky ground. Either way, it's worth wearing sturdy hiking shoes.

Can I enter a cave in Iceland by myself?

Most lava caves require a guided tour for access. Visiting alone is strongly discouraged due to the risk of getting lost or encountering unstable conditions. Proper equipment like helmets and lights is essential, and guides provide these on organized tours.

How many people will be in one group for a caving tour in Iceland?

Most operators have a ratio of one guide to eight customers, though it may vary depending on the tour provider.

What equipment do I need to go caving in Iceland?

You will be provided with a helmet, a flashlight, and crampons in winter. Make sure to bring some warm clothing and sturdy hiking shoes with ankle support.

Can I wear sneakers for my caving tour in Iceland?

Good hiking shoes are much better as they provide better grip and ankle support.

Are lava cave tours operational during Christmas time?

Some lava caves close for the winter, but many, like the Leidarendi cave on the Reykjanes Peninsula, are open throughout the year. Most operators provide services throughout the Christmas season.

Is lava caving safe in Iceland?

Lava caving is a safe activity, as you'll be accompanied by a guide and equipped with a torch and helmet. All you need to bring is decent hiking boots. Follow your guide's instructions, and you should avoid any issues!
