The chances of visiting ice caves are slim in the summer. From mid-March onwards, the temperatures in Iceland slowly increase. The melting water of glaciers makes ice cave walls prone to collapsing. This makes it almost impossible to safely explore ice caves during the summer.
Ice caves can form either when meltwater streams carve a labyrinth at the base of a glacier, or when the biting wind hollows out tunnels in the snowfield and the cold air settles there. Because the formation of ice caves is dependent on fluctuating natural conditions, it is difficult to visit them in the summer when the temperature starts changing again.
If you’ve already planned a summer trip, don’t be disheartened - you can still experience icy enchantment after winter’s end. Named after the Katla volcano, the Katla ice cave underneath the Kotlujokull glacier can be visited all year round. Even if you’re visiting in winter, it is worth checking out the contrasting black and blue walls on the Katla Ice Cave tour.
Whatever month you choose to visit, we have a number of winter tours to keep you occupied. If you would like help with planning, don’t worry. We have covered the best things to do in Iceland each month on our blog. We even have a winter weekend itinerary if you’ve booked that last-minute flight.
You don’t need to bring any special equipment for ice caves. Your tour will include a helmet and crampons. Just dress warmly with layers and get ready to explore the interiors of a magical snow kingdom. Which ice cave would you like to venture into first?
