What is the Crystal Ice Cave?

The Crystal Ice Cave is a natural cave inside Breiðamerkurjökull, an outlet glacier of Vatnajökull — the largest ice cap in Europe by volume — about 4 km from the Jökulsárlón glacier lagoon in southeast Iceland. Each summer, meltwater carves tunnels and chambers into the glacier; each winter the cold freezes them into walkable caves of dense, clear ice. Because the glacier is always moving, the cave re-forms every year, so no two seasons are alike.

Why is the ice so blue?

The colour is not a trick of the light alone. Glacier ice this old has been compressed for centuries until the trapped air bubbles are squeezed out, leaving ice so dense it absorbs every colour of the spectrum except blue. The result is the electric, sapphire-blue glow the crystal caves are known for. Unlike the Katla ice cave under Mýrdalsjökull, which is streaked with black volcanic ash, the Vatnajökull caves are prized for pure, deep-blue ice.

When can you visit? Winter only

The crystal caves are a winter-only experience, roughly from November to late March. They are only stable and safe to enter once temperatures drop and the meltwater channels freeze solid; by spring the thaw makes them unsafe and they close. If you are travelling in summer, the year-round Katla ice cave or the man-made Langjökull ice tunnel are the alternatives. Conditions change daily, and tours are sometimes cancelled for weather with a full refund or a new date.

How you reach the cave

Access is by guided tour only. Tours meet at the Jökulsárlón lagoon car park, where you board a modified super jeep for an off-road ride across the glacial plains to the ice. From the drop-off it is a short walk — anywhere from a few minutes to about half an hour — over uneven ground in crampons your guide provides. There is no self-drive or public route to the cave. At around 380 km (a 5-hour drive) from Reykjavik, this is too far for an easy day trip, so most visitors come on a multi-day South Coast trip or stay near Höfn or Skaftafell.

Crystal, blue, sapphire — are they different caves?

“Crystal Ice Cave” is a general name for the seasonal caves that form in the Breiðamerkurjökull area, not a single fixed location. In some years a particular cave earns a nickname — Sapphire is one — but the caves shift and reshape every winter. Your guide scouts the area and takes you to the best and safest cave open on the day, which is why the one you visit may look nothing like last season's photographs.

Crystal ice cave tours FAQs

How much do crystal ice cave tours cost?
From about $157 per person for the Vatnajokull National Park tour to around $221 for a combined ice cave and glacier walk from Skaftafell. Most crystal cave super jeep tours from Jokulsarlon sit around $174.
When can you visit the crystal ice cave?
Only in winter, roughly November to late March. The natural caves are only stable and safe to enter when temperatures are low; they melt and collapse in the warmer months.
Why can you not visit in summer?
The crystal caves are carved by summer meltwater and only freeze into stable, walkable caves once winter cold sets in. In summer the ice is actively melting, so tours do not run. For a year-round option, the Katla ice cave stays open in every season.
Where is the crystal ice cave?
In Breidamerkurjokull, an outlet glacier of Vatnajokull, about 4 km from the Jokulsarlon glacier lagoon in southeast Iceland.
How far is the crystal ice cave from Reykjavik?
About 380 km, or roughly a 5-hour drive along the Ring Road. It is too far for a comfortable day trip, so most visitors come as part of a multi-day South Coast trip or stay near Hofn or Skaftafell.
How do you get to the cave?
On a guided tour only. You meet at the Jokulsarlon lagoon parking area, ride a modified super jeep off-road to the glacier, then walk a short distance to the cave entrance.
Can I visit the crystal ice cave without a guide?
No. Glacier ice caves can collapse or flood without warning, so entering alone is dangerous and not permitted. Every visit is with a licensed glacier guide.
Why is the ice so blue?
Dense, old glacier ice has had its air bubbles squeezed out, so it absorbs every colour of light except blue. That is what gives the crystal caves their deep, clear blue glow.
What is the difference between the crystal ice cave and the Katla ice cave?
The crystal caves are in Vatnajokull, are winter-only, and are prized for pure blue ice. The Katla ice cave is under Myrdalsjokull, is open year-round, and mixes blue ice with black volcanic ash. Katla is also closer to Reykjavik.
Are the crystal, blue and sapphire ice caves different?
Crystal Ice Cave is a general name for the seasonal caves in the Breidamerkurjokull area. Individual caves get names like Sapphire, but they change every year, so your guide takes you to the best and safest cave open that season.
How long do the tours last?
Most run about 3 to 3.5 hours in total, including the super jeep ride and the walk. The Vatnajokull National Park tour is around 3 hours; the Skaftafell ice cave and glacier walk is about 3.5 hours.
How long do you spend inside the cave?
Usually around 40 minutes to an hour in and around the cave, with the rest of the time spent on the drive and the short walk to reach it.
Is the walk to the cave difficult?
It is generally short and easy, from a few minutes up to about 20 to 30 minutes over uneven, sometimes icy ground. Crampons are provided and a basic level of fitness is enough.
What should I wear for a crystal ice cave tour?
Warm thermal layers, a waterproof jacket and trousers, a hat, gloves and sturdy hiking boots. Crampons and a helmet are provided. Boots matter, as some tours will not let you enter without proper footwear.
Is a crystal ice cave tour safe?
Yes, with a licensed operator. Guides check conditions daily and only enter caves judged stable and safe; if a cave is unsafe, the tour is changed or refunded.
Can the tour be cancelled due to weather?
Yes. These caves are remote and weather can close roads or make the ice unsafe. Operators may cancel and offer an alternative date or a full refund. Every tour here has free cancellation up to 24 hours before.
Are crystal ice cave tours wheelchair accessible?
No. The bumpy super jeep ride and the walk over uneven glacier terrain are not suitable for wheelchairs or strollers.
Is there a minimum age?
It varies by operator; the Skaftafell ice cave and glacier walk sets a minimum age of 10. Check the individual tour before booking if you are travelling with young children.
Will the cave look like the photos?
Not exactly. The caves change every season and even week to week, and colours shift with the light and snow, so your cave may differ from any photo. Guides always aim for the most striking safe cave available.
Can I combine the cave with Jokulsarlon and Diamond Beach?
Yes. The tours meet right by the Jokulsarlon glacier lagoon, and Diamond Beach is next door, so many visitors see both the same day around their cave tour.
Which crystal ice cave tour is best for photography?
The smaller-group tours, such as the Skaftafell ice cave and glacier walk or the crystal blue cave trips, give more space and time for photos, and the guides are used to helping with shots.
Do the tours include hotel pickup?
Some do. The crystal blue ice cave tour can include hotel pickup from Reykjavik or other areas; others are meet-on-location at the Jokulsarlon parking lot. Check each tour's details.
Is it worth it if I have limited time?
If you are short on time and based near Reykjavik, the Katla ice cave is closer and open year-round. The crystal caves are worth the longer journey in winter for their pure blue ice, ideally as part of a South Coast trip.
How old is the ice in the crystal cave?
Very old. The dense blue ice can be centuries old, compressed over time until the air is squeezed out, which is exactly why it looks so clear and blue.
