The Essential Guide To Glacier Ice Caves In Iceland

Natural ice caves are ever-changing glacial phenomena that have created many dream-fulfilling destinations with the unimaginably mesmerizing colors and textures. They look like the work of the diligent craftsmen striving to impress the nature lovers with brilliant ideas and exquisite skills. Inside the ice caves, you will see the incredible nooks, the attractive crannies, the exotic textures, the stunning colors in a range of transparency, and other features. The distinction of each ice cave is irreplaceable.

What Is An Ice Cave and How Is it Formed?

How Ice Caves Are Formed In The Glaciers of Iceland

The Formation of The Ice Caves Takes Place In A Mysterious Way.

The ice caves in Iceland mainly refer to the glacier ice caves. Strictly speaking, since the Icelandic ice caves are formed entirely inside the glaciers and are completely natural phenomena, the term “glacier ice cave” is more accurate. In general, an ice cave can be a regular cave that has a large quantity of ice inside it and it doesn’t need to be 100% made out of ice.

The formation of the ice caves takes place in a mysterious way in which the seasonal melt/freeze cycle plays a major role. The cycle’s huge influence is carried out by summer’s warmer temperatures and increased sunlight then by winter’s low temperatures and cooling down effect.

Starting from spring, the existing ice cave will be eroded by the warmer climate and the heat from increased sunlight. The meltwater on the glacier surface powerfully drains through moulins and travels all the way to the base of the glacier. The rivers keep eroding the glacier ice and carving the natural drainage conduits up to 10 meters (32.8 feet) wide, leaving the void surrounded by crystal ice walls and ceilings. Voila! An ice cave has been shaped. Followed by autumn and winter, lower temperatures bring cool air to further harden the new ice caves and the glacier rivers start to retract. That’s when the new ice caves begin to stabilize. This is also why most natural ice caves are only available to visit from November to March. Only until then are the ice caves safe to explore - with a professional glacier guide, of course.

A perfect example for this type of ice caves is the Crystal Ice Cave at Vatnajokull. It forms every year in a similar way and at close locations.

Why Is Glacier Ice Blue?

Entering an enchanting ice cave feels like going into an exciting alien environment that draws you in. The first and most significant feature you will notice is the shades of blue. Ice caves are known for their distinctive blue color, although not all ice caves are blue.

Glacier ice is much denser and thicker than regular ice, for example, the ice cubes stored in your freezer. It’s a process of centuries, even millennium, for snow to transform into glacier ice. It starts with snow remaining in the same area year-round. When enough pre-existing snow accumulates to transform into ice, it forms an ice layer. Each year, new layers of snow bury and compress the previous layers forcing the previous layers to re-crystallize. During this process, the ice grains begin to grow and the air between the grains are being pushed out causing the snow to slowly compact. So the density of the ice increases. Over time, the ice crystals become so much compressed that there’s hardly any air left between the ice crystals.

Snow looks white because it contains air, which scatters and reflects the full spectrum of light. That’s why the human eyes see the color of snow as “white.” But in glacier ice there’s rarely any air, the light can enter without any disturbance allowing the ice to absorb the light. Glacier ice can absorb the long-wave red spectrum six times more than of the blue spectrum. The deeper the light goes inside glacier ice the more red spectrum the light losses. The lack of the reflected red waves in glacier ice is what makes the human eye perceive the color as “blue.”

Different Ice Caves In Iceland

Crystal Ice Cave

Visiting the Awe-inspiring Crystal Ice Cave At Vatnajokull

Visiting the Awe-inspiring Crystal Ice Cave At Vatnajokull.

One of the most stunning ice caves is the Crystal Ice Cave in Vatnajokull National Park.

To name the ice cave “Crystal” is to capture and express the beauty of the ice walls and ceilings that are translucent enough for the light to come through them. Beneath the ceiling, you will find yourself standing in an amazing environment as if they are made of semi-transparent glass.

Since 2011, the Crystal Ice Caves have formed every year at very close locations because they were crafted by the stream of the same large glacial river each summer. Every year, the newer ice caves always replace the older ones, but they are distinctively different except sharing only one indescribable feature - the iridescent blue ice. It’s one of the most photogenic scenes in Iceland. And you will have enough time for photography during a guided experience. As one of the most awesome, must-do experiences in Iceland, visiting Crystal Ice Cave will be unforgettable. The closest departure to this natural wonder is from Jokulsarlon Glacier Lagoon, a location that is a mesmerizing wonder itself. There are multiple departures from there every day!

Katla Ice Cave

Katle Ice Cave Within Myrdalsjokull Glacier

Visiting The Ice Cave Under Katla Volcano.

Katla Ice Cave was only discovered a couple of years ago and it’s already one of the most famous ice caves in Iceland. To quote the local’s comment on this special one, “it’s a cool ice cave that people can visit all year around.”

Its location is right on the mighty Myrdalsjokull glacier, the fourth largest glacier in Iceland. Beneath it, there lies the notorious “monster volcanoKatla. The extreme condition of this area has created many spectacular sceneries. As one of these spectacles, the glacier that created Katla Ice Cave stands above an open, hilly area filled with black volcanic sands. In winter, when the land is covered by snow, the striking contrast between volcanic black and icy white resembles a land from an alien planet.

The Striking Contrast Between Volcanic Black And Icy White Resembles A Land From An Alien Planet.

In front of the opening to Katla Ice Cave, you will see the unusual colors, the beautiful layers, the streaming glacial waterfalls, and the intricate textures in magnificent volume. The veins of the black volcanic ash swirl together with the ice making a photographer's wildest dream come true. Mixed with some of the rare colors found in nature - glaring snow white and metallic icy blue - the ice cave surface presents a unique look and is quite a spectacle to witness.

Katla Ice Cave sometimes is also referred to as “Nature Ice Cave in Myrdalsjokull.” Because it’s entirely natural and is subject to change over the course of time, don’t wait around for another time or another chance. If you are based in Reykjavik, Hveragerdi, Hella or Hvolsvollur, there are tours to Katla Ice Cave offering free pickups from many hotels. On your way, you will stop by the astonishing Seljalandsfoss and Skogafoss waterfalls. Or you can join the group directly at ICEWEAR / Vik Wool Store if you are self-driving or already in Vik. Then, you get to take a thrilling super jeep ride to see the pristine glaciers.

What To Be Aware Of When You Visit An Ice Cave

Safety Instruction From An Experienced Glacier Guide

Safety Instruction From An Experienced Glacier Guide

The first thing the visitors must know is that never visit an ice cave without a glacier guide. The ice caves are usually located in a higher place on the glaciers. It either requires a short glacier hike or a brief ice climbing, both can be dangerous if you are not following the track mapped by the glacier guide who’s trained and experienced in everything related to glaciers. There can be cracks, crevasses and falling down can be fatal. With a well-trained eye, the glacier guide is familiar with his guiding area and is always on a full alert about the weather changes.

And, wearing the suitable outfits is essential. On the glacier, the weather can be windier than on the ground. Inside the ice cave, the temperature is always cooler and chillier than the outside. Only dressing in layers and wearing the right fabrics can help you adapt to so many different activities during one trip. This detailed glacier adventure dress guide  shares many insights on how to choose the right outfit like a professional.

How To Get To The Glaciers

Many glacier tours depart from Reykjavik or the Capital Region. They often offer free pickups at locations close to numerous hotels and hostels.

If you are staying in Vik, Skaftafell and Jokulsarlon area, they are multiple departures to the glaciers daily from these locations.
