Inside Vatnajökull Ice Cave, Iceland’s “Anaconda Ice Cave”

Vatnajökull Ice Cave is also known as Anaconda Ice Cave and Crystal Ice Cave. The glacier gets its “crystal” name because of its crystal-blue ice; and it’s sometimes called “anaconda” because it’s long and winding, like the fearsome snake.

It’s an incredible experience, entering a glacier and seeing the pure, crystal ice within.

Here, we’ll tell you a little about the glacier itself, and then discuss the incredible ice cave.

You can experience this unbelievable site on our Vatnajökull Ice Cave Tour with Glacier Hike.

Vatnajökull: Iceland’s Biggest Glacier

Sometimes called “Vatna Glacier”, Vatnajökull is the largest icecap in Europe, covering an estimated 8% of Iceland. It spans a humbling 7,900 km2 and – like many glaciers – covers several volcanoes.

As you might expect from such a titan of nature, the glacier has created several smaller wonders; including glacier lagoons, rivers, breath-taking canyons and vast waterfalls.

You can find out more about the glacier and the region in our guide to Vatnajökull Glacier and Vatnajökull National Park.

What Does Vatnajökull’s Crystal Ice Cave Look Like?

Standing at the gigantic entrance to Crystal Ice Cave, the texture of the ice glistens in the sun. Looking ahead, the tunnel appears endless as shades of blue descend all the way to create a hole of darkness. The blue ice arch is spectacular, underneath runs a small stream surrounded by bright blue ice chunks. It’s was absolutely beautiful to see.

Stepping into the Ice Cave

Entering the Ice Cave, you can get a sense of the surroundings by checking out the crystal ice ceiling.

The guide will tell you about how ice appears the way it is and how ice caves begin to form and stabilize, explaining the ins and outs of the amazing natural phenomenon. Anaconda Ice Cave is so impressively spacious and it’s safe to say that it’s one of the largest ice caves found in Iceland so far.

Colors in the Ice Cave

In addition to the sheer size, the blue glacier ice is another highlight. Glacier ice looks blue due to the density of the ice. The ice is also much thicker and denser than regular ice, for example, an ice cube in your freezer. It’s a result of a process that takes hundreds of years of snowflakes falling and compressing and re-crystallizing into ice, during which air bubbles trapped in the ice will be pushed out.

When a chunk of ice is too dense to have any air in it, light travels deeper. The deeper the light travels, the more red-coloured spectrums it loses along the way, making the ice appear blue to our eyes. That’s why the glacier ice in Iceland has that magical, otherworldly shade of blue.

A little hike before the Ice Cave

Before reaching the ice cave, the guide will assist you in putting on crampons and helmet for a short glacier hike. Participating in the ice cave tour has two options, you can join them directly from Reykjavik or you can choose to visit crystal ice cave meet on location at Jokulsarlon Glacier Lagoon.

Things to do near Vatnajokull Ice Cave

While you’re in the area, there’s an abundance of fantastic things to see and do…

Jokulsarlon Glacier Lagoon

Jokulsarlon Glacier Lagoon is one of the most popular attractions en route to Vatnajokull. It’s a gorgeous glacial lake that only came to existence in the 1920s and it continues to expand. Now as the deepest lake in Iceland, the depth of Jokulsarlon can reach down to 248 meters (814 feet) and it carries huge icebergs away from Breidamerkurjokull glacier tongue to the North Atlantic Ocean.

Diamond Beach

On their way out of this lagoon, its floating icebergs got stranded on the black volcanic beach resulting in a spectacular scene with diamond-like ice cubes spreading over the beach, and that’s how the black sand beach got its glamourous name – the “Diamond Beach”.

Vatnajokull Super Jeep and Boat Tours

Many tours in the Vatnajokull National Park depart from the glacier lagoon including Vatnajokull super jeep tours, tours to the ice caves, and in the summertime Jokulsarlon lagoon boat tours are highly recommended.

Iceland’s South Coast

On your way to Jokulsarlon, the scenic ride along the South Coast of Iceland is one of the most strongly recommended trips and you will stop by many iconic attractions including Seljalandsfoss, the waterfall you can walk behind; Skogafoss, one of Iceland’s biggest and most beautiful waterfalls; Reynisfjara, the famous black sand beach; and the beautiful seafront town Vik, home to beloved Puffins in summer and a terrific ocean view backdropped by ice-capped mountains.
