The Icelandic ice caves are some of the world’s most awe-inspiring natural wonders. You can find these frozen monuments to nature’s power and beauty on the outlet glaciers of Iceland’s many ice caps

Over 11% of the Icelandic landmass is covered by massive sheets of ice known as glaciers, leaving no doubt as to why the country bears its name. These glaciers are so enormous that they cover mountains, valleys, and, often, active volcanoes, like a white sheet of bed linen.

This interplay of hot and cold—glaciers and volcanoes—allows the formation of beautiful ice caves. Visiting any of these magical glacial grottoes often tops many visitors’ bucket lists.

With day trips, super jeep tours, and experienced guides all available for hire, it has never been easier to explore Iceland’s stunning ice caves.

The Science Behind the Ice Caves: How They Form and What Makes Them Unique

The Icelandic ice caves are some of the world’s most awe-inspiring natural wonders. You can find these frozen monuments to nature’s power and beauty on the outlet glaciers of Iceland’s many ice caps.

The majority of Iceland’s glaciers started forming approximately 2500 years ago. Over the centuries, pools of water concentrated and condensed to form glaciers which cover many of this country’s mountains and volcanoes.

These enormous ice bodies are consistently on the move. They are sculpted by surrounding mountainsides or the pressure of their own weight. Other factors, including the speed of their motion, can cause the glaciers to twist and turn in peculiar ways. This movement often leaves open crevasses, which, when filled with meltwater, create deep vertical shafts known as moulins.

Iceland is a country with high volcanic and geothermal activity. The glaciers covering volcanoes have volcanic vents or hot springs emitting heat, which creates more meltwater. When the water pours down the glacier moulins, it digs tunnels in the ice.

These tunnels are commonly known as ‘ice caves’. However, the correct term is actually ‘glacier cave’. In geology, ‘ice caves’ is the proper term to describe rock caves containing year-round ice, such as Víðgelmir cave in West Iceland. But we will continue to use the more common ‘ice caves’ term here.

Discovering the Best Locations of Icelandic Ice Caves: From Reykjavik to Vatnajökull

Most visitors to Iceland arrive at Keflavík International Airport before making the short drive to Reykjavík. Both the airport and the capital are located in the western part of the country. However, the most popular ice caves—known as The Blue Ice Caves—are inside Vatnajökull Glacier, found in Southeast Iceland.

Travelling to these caves can take up to two days. However, the journey is very scenic, with plenty of photography stops along the way. Those with more limited time in the country can either visit the Katla Ice Cave, located on the south coast, the natural cave on Langjökull, or one of the man-made caves that are closer to the capital.

The most famous ice caves are found within Vatnajökull National Park. They are in southeast Iceland, around 380 km (49.7 mi) from Reykjavík. Unfortunately, Vatnajökull’s ice caves are only accessible during the winter months. That is because summer sees these subterranean tunnels flood with glacial water, thus becoming inaccessible. Therefore, visiting Vatnajökull ice caves is only possible from August to April each year.

The national park is named after its star attraction, the mighty Vatnajökull ice cap (meaning “Water Glacier”), which covers an incredible 8% of the country’s landmass (8,500 square kilometres). Vatnajökull’s size not only makes it Iceland’s largest glacier but also Europe’s.

Vatnajökull has about 30 outlet glaciers, or glacier tongues, flowing from the ice cap. Although you can probably find an ice cave in most of them, many are inaccessible. Among the most popular outlet glaciers for ice cave excursions are Svínafellsjökull, Eyjabakkajökull, Falljökull, and Skaftafellsjökull.

Collectively called “The Blue Ice Caves”, these glittering caves twist and turn elegantly inside the glacier, creating a stunning scene one must see to believe. These caves sometimes go by different names depending on the tour operator, such as “Crystal Cave”, “Blue Diamond Cave”, “Waterfall Cave”, “Sapphire Ice Cave”, and even “Northern Lights Cave”.

In essence, the names are merely a marketing trick. Because the caves flood —and sometimes collapse—each season, this year’s Crystal Ice Cave might be completely different from last year’s Crystal Cave.

From Where do Blue Ice Cave Tours Depart?

The distance between Reykjavík and Vatnajökull, paired with winter driving conditions, make visiting these ice caves from the capital a two-day journey. However, staying overnight at a country hotel gives guests more time to enjoy the many attractions found along the way.

Guided multi-day tours to ice caves depart from Reykjavík city and include sightseeing stops along the South Coast. These often include the sites on the Golden Circle, Reynisfjara Black Sand Beach, Jökulsárlón Glacier Lagoon, and the Diamond Beach.

Stand-alone day trips—perfect for self-drive tours—usually depart at Jökulsárlón Glacier Lagoon, but sometimes at Skaftafell Nature Reserve.

Most tours require a short glacier hike through beautiful frosty landscapes to reach the cave. However, adventure-seekers looking to avoid crowds can book a longer ice cave tour where they’ll have to hike for about 1.5 hours each way.

Katla Ice Cave in South Iceland

Closer to Reykjavík is the Katla Ice Cave in Mýrdalsjökull Glacier, which is about 167 km (42 mi) west of the capital. The cave itself is named after Katla Volcano, on which the ice sits.

Unlike other natural ice caves, the Katla Cave is available to visit all year round. This makes it a must-see for summer travellers who thought they might otherwise miss their chance to visit one of these true natural wonders.

Aside from the Katla Ice Caves being accessible year-round, the main difference between the Katla Ice Cave and the Blue Ice Caves in Vatnajökull is the colour of the ice. Although you can find blue ice at Katla, the cave is much darker. The ice is also streaked with black ash from past volcanic eruptions.

From Where do Katla Ice Cave Tours Depart?

Most tours which visit the Katla Ice Cave will depart from either Reykjavík or the seafront village, Vík í Mýrdal. The excursions from the capital will often include sightseeing stops at the Seljalandsfoss and Skógafoss waterfalls and the black sand beach, Reynisfjara.

There are usually two departure times for the Katla Ice Cave from Vík. The morning departure is perfect for those on a self-drive tour and overnighting near the town. In contrast, the afternoon departure is more suited for those starting the day further away, such as Reykjavík or Kirkjubæjarklaustur.

Langjökull Glacier’s Ice Caves

The closest ice caves to Reykjavík are the ones found at Langjökull, the second-largest glacier in the country. This massive glacier in the Icelandic highlands has a natural ice cave open to visitors between October and January. Additionally, there are man-made ice tunnels that allow visitors to explore the glacier’s interior in a unique and exciting way.

Unlike most natural ice caves, the tunnels at Langjökull Glacier can be visited all year round. This is because the man-made tunnels remain stable and more constant in temperature than their natural counterparts.

For both the ice tunnels and natural cave, visitors must ride in a massive glacier truck to reach the attractions. This only adds to the drama and exhilaration of visiting.

For those interested in visiting the ice tunnels on Langjökull, there are two main departure points. The first option is from Reykjavík city, which includes sightseeing stops along the way. The other option is from Húsafell, located close to the glacier itself.

For tours to the natural ice cave, a guide will pick up visitors at Gullfoss Waterfall on the Golden Circle route.

From Lake Mývatn, you can take a guided tour of the always-staggering Lofthellir cave. Note that Lofthellir is an “ice cave” in the scientific meaning of the word and not a “glacier cave” like the others mentioned above (remember, we talked about the difference earlier).

This ethereal cavern is famous for its fantastic, naturally-formed ice sculptures and stalactites. Lofthellir formed over 3500 years ago and extends an incredible 370 meters (1213 ft) underneath the Laxardalshraun lava field.
