Caves in Iceland

There’s a side of Iceland that most people walk right by. To get there, you’ll need a helmet, a flashlight, and a keen sense of adventure. We’re talking, of course, about Iceland’s awe-inspiring caves.

You’ll find two types of caves here: lava caves, and glacier caves. The former are the byproduct of volcanic eruptions, which can create tantalizing tubes and chambers below ground. Glacier caves, on the other hand, are exactly what they sound like -- large passageways carved through the ice by flows of liquid water.

Lava caves can be found all over Iceland, and some can be easily traversed on your own. Others are more remote, and require the presence of a guide. While some intrepid explorers will happily spend several days hiking out to the perfect cavern, there are many caves that can be accessed as part of a day trip. If you’re visiting the countryside during your stay in Iceland, we recommend making some time to check out these geological wonders firsthand.

If you’re more drawn to ice than rock, Vatnajökull glacier is the primary location for caving. Glacier caves can be hard to find, so going with a guide is vital. You’ll need an experienced spelunker to lead you through these magical passageways. Though trekking through a glacier may sound challenging, many tour groups offer short trips (2-4 hours) aimed at beginners.

As with any sort of physical activity, caving is best for those in good health, and is safest when enjoyed as a group. Though you’re likely to come across small caves and crevices out in the countryside, it’s wise not to venture into anything that is unmarked. Stick to the path, follow your guide, and you’re sure to have a fantastic time.
