The ice caves there are only accessible during the winter months, typically from mid-November to late March, when conditions are cold and stable enough to ensure safety.
Visitors cannot access the cave on their own; it is only possible to visit with a certified glacier guide as part of organized Ice Cave tours. These ice cave tours generally depart from Jökulsárlón Glacier Lagoon, which serves as the main meeting point for visitors.
The term "Crystal Ice Cave" is a general name used to describe the seasonal ice caves that form in the Breiðamerkurjökull glacier. Although the name remains the same, the cave can differ yearly.
The caves there are naturally formed by meltwater during the summer months and are sculpted into new shapes each winter. As a result, each visit offers a unique experience depending on the conditions that season.
Each winter, professional glacier guides explore the glacier to locate new ice caves that can be used for tours. The caves are selected based on their size, visual appearance, accessibility, and safety. Only caves that meet strict safety standards and offer a visually impressive experience are chosen for daily tours.
The Ice Caves in Breiðarmerkurjokull are known for their deep blue ice and smooth, transparent walls. The intense blue color occurs due to the density of the ice, which absorbs most light wavelengths except for blue. Light filtering through the cave highlights the clear ice structures, creating an otherworldly atmosphere that draws photographers and nature enthusiasts from around the world.
Access to the cave involves a ride in a specially equipped super jeep and a short guided walk on the glacier. Safety equipment such as helmets and crampons are provided. Because the cave is located in a remote glacial area, and due to the potential dangers of unstable ice and changing weather, visiting without a guide is not permitted.
The Crystal Ice Cave is considered one of the must-see winter attractions in Iceland. However, due to its popularity and limited seasonal accessibility, booking a tour in advance is highly recommended.
