What is Breiðamerkurjökull?

Breiðamerkurjökull is an outlet glacier of Vatnajökull, Europe's largest glacier. A glacier outlet is a tongue or flow of ice that extends from the cap, resembling a frozen river flowing out from the main ice mass. A simple analogy is to envision your hand, where the palm represents the ice sheet and the fingers represent the outlet glaciers through which the ice flows. Breiðamerkurjökull is one of these outlet glaciers, extending like a finger from the larger ice cap, Vatnajökull.

Breiðamerkurjökull is famous for the ice caves that have formed in its valley. These unique wonders showcase the incredible color spectrum which ice can create, from blues to blacks. The ice caves are incredibly beautiful and popular with visitors; however, they can also be dangerous. If you are hoping to visit, make sure you book an ice cave tour.

How are Breiðamerkurjökull Glacier Ice Caves Formed?

The ice caves of Breiðamerkurjökull are ever-changing. The push of the Vatnajökull glacier moves the ice further down the outlet, which means the caves are constantly moving. It isn't just the location that moves year on year; with ice melting during the summer and freezing again in the winter, every year the ice caves form new shapes, patterns, and inlets.

It's important to note that ice caves and glacier ice caves are formed differently. Ice caves can be a cave that is just partly covered in ice. A glacier ice cave is formed from the sheet of the glacier, meaning that while inside, you are covered by nothing but the ice above.

When to Visit Breiðamerkurjökull?

Although the glacier and surrounding scenery are captivating all year round, the best time to visit Breiðamerkurjökull and its ice caves is in the winter. This is when the ice is frozen making the unique tunnels and holes. Make sure you booked onto a guided tour of the crystal caves which run from October to April.
