It is undeniable that visiting an ice cave during your trip to Iceland is a must. We have put together the ultimate guide on ice caves that gives you a comprehensive overview of ice caves and answers a range of frequently asked questions.

Difference between ice caves and ice glacier caves?

It is important to know the difference between a glacier cave and an ice cave as if you use the terms interchangeably you may mistakenly end up going into a cave of unexpected disappointment.

The main difference is as follows:

Glacier caves are probably what you are dreaming of when you say ‘ice caves’, glacier caves are made entirely of ice.
Ice caves are natural cave formations that have a significant amount of ice inside: such as, Vatnajökull and Mýrdalsjökull ice caves.

When is the best time to visit ice caves in Iceland?

Whilst there are two glaciers that are accessible throughout the year, the best time to go to see a natural glacier ice cave is wintertime – specifically from early November to the end of March. The ice cave season is quite short in Iceland, as the weather must be cold enough. Outside the cave season, there is the danger of the caves collapsing if temperatures drop.

Why are ice caves in different colours?

There is a brilliant variety among ice caves, they can be an amalgamation of colour, opaqueness and transparency, it is quite rare for a cave to be a singular colour. Naturally occurring ice caves in Iceland can come in varying shades of black, grey, white or blue. The blue quartz crystal colour of the ice is due to the air bubbles in the ice being eradicated and compressed over centuries; for example, Vatnajökull crystal ice cave. The colour of the ice is often intensified if there are algae present, leading to more brilliant aquamarine and violet hues. Deep anthracite and black ice are also known to colour the caves. For example, the ice cave known as ‘Dark Rubin’, in Vatnajökull is adorned with black ice. In Mýrdalsjökull glacier, another dark ice cave with black colouring can be discovered.

What are the best ice caves in Iceland to visit?

Ice caves in Iceland come and go, they melt with spring and recreate themselves in winter. Also, each cave is unique, the ‘best’ ice cave depends on what you are looking for, it depends on a number of variables like desired colour, location, etc. Ahead of travel check which glacial caves are popular in Iceland and safe to visit. Don’t limit yourself to natural ice caves. There are also man-made caves like the Langjökull ice cave, which can be visited all year round, even in the summer. It maintains a perfect balance between nature and man; there are amazing stalagmites and stalactites that adorn the cave, but it also has cool furnishings and a built-in chapel.

In contrast, the natural Vatnajokull ice caves, located in Breiðamerkurjökull and famed for the turquoise blue colouring, the Crystal Ice Cave is considered the most famous of ice caves in Iceland. In the northeast highlands of Vatnajokull, you can find the Kverkfjoll ice caves, which are equally unique. Vatnajokull has the largest ice glaciers in Europe.
