Ice cave Iceland: caves, glacier hikes and how to do them safely.

An ice cave in Iceland is a winter thing that melts away every summer, and it's only ever done with a guide. Here's when the natural caves open, the ice caves and tunnels you can visit all year, which glacier hike to pick, and what changed after the 2024 accident.

The short version

• Natural blue ice caves in Vatnajökull are a winter thing. They open roughly October or November to March or April, depending on how cold the autumn is, and only with a guide.
• If you're here in summer, you still have two real options: the Katla ice cave from Vík, and the man-made ice tunnel in Langjökull. Perlan in Reykjavík has an indoor ice cave for a rainy afternoon.
• Glacier hikes run all year. Sólheimajökull is the closest to Reykjavík, about two hours' drive. Skaftafell is further but bigger and bluer.
• Never walk onto a glacier without a certified guide. Crevasses hide under snow, and ice caves collapse. This isn't the place to save money.
• You can book ice cave tours and glacier hikes with Icebreaker, and check road conditions before you drive the south coast in winter.

An ice cave in Iceland is not a permanent attraction like a waterfall. Most of them are channels carved by meltwater running under a glacier in summer. When the melt stops in autumn, the channel is left empty, the ice around it freezes hard, and for a few months you can walk inside. Next summer the river runs again, the roof sags or collapses, and the cave is gone. Guides go out every autumn to find the new ones. That is why the cave you see in someone's photo from two years ago probably doesn't exist any more, and why nobody can promise you a particular one.

When is ice cave season in Iceland?

For the natural caves in Vatnajökull, Europe's largest ice cap, the season runs through the cold months. Operators generally sell it as October to April, but the honest answer is: when the guides say so. A mild, rainy autumn can push the first trips into November, and a warm spring ends them early. The deep blue colour people come for is at its best in the middle of winter, December to February, when the ice is hard, clear and the light is low.

Since the 2024 accident (more on that below), ice cave tours inside Vatnajökull National Park stop over summer. In 2025 the last trip ran on 30 April, and caves reopen in autumn once a group of experienced lead guides assesses them as safe. Every cave is now checked daily in season, and a cave that fails the check is off-limits for the day, even if you booked it months ago.

Where the natural caves are

Most tours leave from Jökulsárlón or the Skaftafell area on the south side of Vatnajökull, roughly 4 to 5 hours' drive from Reykjavík in good conditions and longer in winter. The trip you'll see sold as the crystal ice cave tour usually starts at Jökulsárlón, with a super-jeep ride to the glacier edge and a short walk to whichever cave is safe that week. Expect 2.5 to 3 hours in total, and prices from about 22,000 ISK per person (2026 prices, which change). Skaftafell has its own blue ice cave tours on Falljökull, usually combined with a glacier walk.

Ice caves you can visit all year

Katla ice cave, from Vík

The Katla ice cave is in Kötlujökull, an outlet glacier of Mýrdalsjökull, the ice cap that sits on top of the Katla volcano. Tours meet in Vík and drive out by super jeep, about 30 minutes each way. The ice here is streaked black with volcanic ash, so it looks different from the Vatnajökull caves: less pure blue, more black-and-white marble. Because it's darker and more sheltered, it runs year-round, and it's the only natural ice cave most summer visitors will see.

Short versions from Vík take about 2 hours and start from about 23,000 ISK; longer ones with more time on the ice run to about 40,000 ISK (2026 prices). Minimum ages vary by tour, from about 6 on the short family trips to 12 on the longer ones. Tours from Reykjavík exist too, but that's a 12-hour day, most of it in a minibus. The guide picks the cave on the day, and in summer it can be wet and drippy inside. It's still a glacier, so conditions decide.

Langjökull ice tunnel, the man-made one

The Langjökull ice tunnel (sold as Into the Glacier) was dug into Iceland's second-largest glacier and opened in 2015. It's man-made, lit, and maintained, so it's the steadiest option on this list: open all year, and more forgiving for kids and less-steady walkers. Tours leave from Húsafell in West Iceland, about 2 hours from Reykjavík, and a converted glacier truck takes you up onto the ice. The ice is not the deep blue of a natural cave, but you do get a proper sense of being inside a glacier, with layers of old ash and a crevasse you can look into safely.

The classic tour from Húsafell starts from about 25,000 ISK; with transfer from Reykjavík it's about 39,000 ISK, and snowmobile combos cost more (2026 prices). Children are welcome on most departures, which makes it the easiest ice experience for families. Book it with Icebreaker.

Perlan, the rainy-day version in Reykjavík

If the weather has cancelled your glacier plans, or you have small children, Perlan's ice cave is a 100-metre tunnel built inside the museum from more than 350 tonnes of snow. It's cold, real ice, and entirely safe. It's not a glacier, and nobody should pretend it is, but it's a good hour alongside Perlan's exhibitions and viewing deck. Adult tickets cost from about 6,000 ISK online and a bit more at the door (2026 prices). See our things to do in Reykjavík guide for what else is nearby.

Glacier hike Iceland: Sólheimajökull and Skaftafell

A glacier hike is the other half of this: walking on the surface of the ice in crampons, with a guide, past crevasses, moulins and ridges of blue ice. Unlike the natural ice caves, hikes run all year. In summer the surface is grey, wet and more broken; in winter it's harder, cleaner and colder.

Sólheimajökull glacier hike

Sólheimajökull is an outlet glacier of Mýrdalsjökull, just off Route 1 between Skógafoss and Vík. It's about 160 km, or 2 to 2.5 hours, from Reykjavík, which makes it the only glacier hike you can comfortably fit into a south coast day trip. Several operators have bases in the car park. There's a parking fee, and a 10–15 minute walk to the ice past the lagoon that has formed as the glacier retreats.

Standard walks take about 3 to 3.5 hours with 1 to 1.5 hours on the ice and start from about 15,000–17,500 ISK. Longer, more technical hikes with more time on the ice cost about 21,000 ISK, and ice climbing more again (2026 prices). Minimum age is typically 8 to 10 for the easy walks and 12 or older for the longer ones. Pick-up from Reykjavík is usually offered as an add-on.

Skaftafell glacier hike (Falljökull)

Skaftafell, in Vatnajökull National Park, is where the glaciers get serious. Most hikes go onto Falljökull or neighbouring tongues coming down from Öræfajökull, Iceland's highest mountain. The ice is steeper, more crevassed and, in our opinion, more impressive than Sólheimajökull. Easy 3-hour walks start from about 15,000 ISK, with 5-hour hikes, ice climbing and winter blue ice cave combos above that (2026 prices). Minimum age on the easy walks is usually 8. It's about 4 hours from Reykjavík, so treat it as an overnight trip.

Jökulsárlón glacier lagoon: boat and kayak tours

In summer, when the Vatnajökull ice caves are closed, Jökulsárlón is where the glacier trip goes instead. The lagoon fills with icebergs calved from Breiðamerkurjökull, and you can get among them three ways:

• Amphibian boat. 30–40 minutes, runs roughly May to November. About 7,100 ISK for adults, less for children, free for under-6s (2026 prices). Good for families.
• Zodiac. About 1 hour 15 minutes, May to October, and gets much closer to the ice and up towards the glacier face. About 16,600 ISK for adults; children from 10 (2026 prices).
• Kayak. Guided, in summer, around an hour on the water. The quietest way to see it. Minimum ages are higher, usually early teens, and you'll wear a drysuit.

Diamond Beach, where the icebergs wash up on black sand, is across the road and free. Boat tours sell out on summer afternoons, so book ahead if you have a fixed day.

The 2024 Breiðamerkurjökull ice cave accident and what changed

On 25 August 2024, a group of 23 people on a guided ice cave tour on Breiðamerkurjökull, in Vatnajökull National Park, was hit when part of an ice arch near the cave collapsed. A tourist from the United States was killed and his partner was seriously injured. Because the booking list initially showed 25 people, a large search went on through the night for two people who, it turned out, had never been on the trip.

The accident happened in late summer, and it put the focus on summer ice cave tours in particular. A glaciologist's risk assessment from 2017 had already warned that summer conditions were too dangerous for ice cave visits, and some operators had kept running them anyway. What followed:

• Vatnajökull National Park suspended ice cave tours straight away and banned tours under ice roofs or arches while new rules were written.
• From November 2024, operators working in the park had to take part in daily safety assessments of each ice cave and overhanging formation, run by experienced lead guides. If a site is judged unsafe, nobody goes there that day.
• A professional council with the park, operators, mountain guides and industry bodies now oversees this, and operators pay into it per guest.
• Ice cave tours in the park now stop over summer. In 2025 the last trip ran on 30 April.
• The government set up a working group on safety in adventure tourism. As of 2025, glaciers outside the national park, including Mýrdalsjökull where the Katla cave is, were not covered by the same rules, and it was up to each operator to assess safety.

What that means for you: pick an established operator, don't push a guide who says a cave is closed, and be wary of anyone selling a natural blue ice cave in Vatnajökull in July.

Is it safe? Guides, gear, fitness and minimum ages

What gear is provided

On a guided glacier hike or ice cave tour the operator provides the technical kit: crampons, a helmet, a harness and usually an ice axe, plus headlamps in the caves. You bring the rest:

• Stiff hiking boots with ankle support. Crampons don't fit trainers. Most operators rent boots if you don't have them.
• Waterproof jacket and trousers. Glaciers are wet, even in winter. Rentals are usually available.
• Warm layers, hat and gloves. It's colder on the ice than in the car park, and colder still inside a cave.
• Snacks and water for longer hikes.

Our Iceland packing list has the full layering system.

Fitness

The easy glacier walks and most ice cave tours need normal fitness: you can walk for an hour or two on uneven ground and up short slopes. Walking in crampons feels odd for the first ten minutes, then it's fine. The longer hikes and ice climbing are properly physical. If you have knee or balance issues, the Langjökull tunnel or Perlan are the better call.

Minimum ages

There's no national rule; each tour sets its own, largely by boot and crampon size. As a guide: the Langjökull tunnel takes young children, the shorter Katla trips from about 6, easy glacier walks and Vatnajökull ice caves from about 8, and longer hikes, ice climbing and kayaking from 12 to 14. Check the specific tour before you book.

FAQ

When is ice cave season in Iceland?

Natural ice caves in Vatnajökull are open roughly October or November to March or April, depending on the weather, and are best from December to February. Since 2025, tours in Vatnajökull National Park stop over summer. The Katla ice cave and the Langjökull ice tunnel are open all year.

Can you visit an ice cave in Iceland in summer?

Yes, but not the blue caves in Vatnajökull. In summer your options are the Katla ice cave from Vík, the man-made ice tunnel in Langjökull, and the indoor ice cave at Perlan in Reykjavík.

Can I visit an ice cave or hike a glacier without a guide?

No. Glaciers have hidden crevasses and ice caves can collapse. Always go with a certified glacier guide, who brings crampons, helmets and harnesses and checks conditions on the day.

What is the closest glacier hike to Reykjavík?

Sólheimajökull on the south coast, about 160 km or 2 to 2.5 hours' drive from Reykjavík. Easy guided walks start from about 15,000 ISK and run all year.

How much does an ice cave tour in Iceland cost?

From about 22,000 ISK for a Vatnajökull crystal ice cave tour from Jökulsárlón, about 23,000 ISK for a short Katla ice cave tour from Vík, and about 25,000 ISK for the Langjökull ice tunnel from Húsafell. These are 2026 prices and change; pick-up from Reykjavík costs more.

What happened at the Breiðamerkurjökull ice cave in 2024?

On 25 August 2024, part of an ice arch collapsed during a guided ice cave tour on Breiðamerkurjökull, killing a US tourist and seriously injuring his partner. Vatnajökull National Park then introduced daily safety assessments of every cave and stopped ice cave tours over summer.

What is the minimum age for ice cave tours and glacier hikes?

It depends on the tour. The Langjökull ice tunnel takes young children, short Katla trips start from about 6, most Vatnajökull ice caves and easy glacier walks from about 8, and longer hikes and ice climbing from about 12.
