Must-Know Tips for Ice Caving in Iceland

In addition to understanding what to wear on ice cave tours in Iceland, these tips will help you make the most of your glacier adventure.

For ice caving in Iceland, plan your visit between October and March to experience the most stable and vibrant ice caves.
Consider summer options like the Katla Ice Cave or Into the Glacier tunnel if visiting outside winter.
Choose your departure wisely. Reykjavik is convenient for day trips or short stays, while Jokulsarlon Glacier Lagoon offers full-day glacier adventures and is ideal for travelers exploring Iceland by self-drive.
Dress in layers to stay warm, dry, and comfortable inside the glacier.
Confirm safety equipment with your operator. Helmets and crampons are usually provided, but it’s best to double-check before your tour.

Layering and Clothing Essentials for Ice Caving

Proper clothing is crucial when exploring Iceland’s ice caves, as relying on a single piece of outerwear won’t keep you comfortable. The key is to layer your clothing!

You'll want to start with a soft base layer and insulated trousers, as they will help regulate body heat and keep you warm! Look for items such as a soft merino wool shirt and matching pants, as your choice of material can matter greatly. Thick woolen or thermal socks are also a must, as you don't want to let freezing cold toes ruin your experience.

Then you'll want to add mid layers. A quality fleece sweater or light sweater is perfect for this, and you'll want to add shell pants that are fully windproof and waterproof. If you're hiking during the height of winter, you'll also want to add another insulating layer, like a fleece vest.

On top, you'll need a good shell layer to lock in heat and protect you from water dripping from the ice cave ceiling. It's essential that your jacket of choice is fully wind and waterproof, such as a good down GORE-TEX jacket. Trusted Icelandic brands like 66°North offer reliable outerwear built for the harsh conditions.

To complete the outfit, add a warm beanie or hat that covers your ears well and warm, waterproof winter gloves.

For your feet, you must have good hiking boots with a sturdy, stiff sole. On top, you'll need to add sturdy crampons or spikes, which the tour operator can sometimes provide! We do recommend investing in some or renting crampons on Iceland's largest travel marketplace, as they'll also be very useful when exploring the rest of Iceland during winter.

Special Equipment for Ice Caving in Iceland

Knowing what to wear on ice cave tours in Iceland is just as important as bringing the right equipment to ensure a safe and enjoyable experience. You can generally expect that your chosen tour operator will provide most, if not all, of it, but it's good to keep in mind!

Firstly, a sturdy helmet is essential for protection against potential falling ice or low-hanging cave ceilings. It's a basic safety measure that can't be overlooked and is generally provided by your tour operator.

Additionally, carrying a headlamp or a flashlight is crucial as the caves can be dark, and having your own light source will help you see the path ahead and fully appreciate the cave's features. It can also be very helpful when navigating the winter darkness.

Next, unsurprisingly, ice caves are slippery, as they're quite literally just a bunch of ice. This makes crampons or ice cleats a necessity. If you don’t want to invest in heavy-duty ones for your trip, check whether your tour operator provides them or consider renting crampons. These attachments to your boots will provide the necessary grip to help you navigate the icy terrain confidently.

Lastly, don't forget a waterproof bag to keep your camera and other personal items dry. You'll likely want to capture the beauty of these ice caves, so protecting your equipment from damp conditions is important!

What to Wear on Ice Cave Tours in Iceland by Season

Visiting ice caves in Iceland is an unforgettable experience, and the season of your visit will shape both the conditions inside the glacier and what you should wear.

The majority of natural ice caves are only accessible from October to April, when temperatures are low enough to keep the caves stable and safe to enter. Our study of the safest month to visit ice caves in Iceland found that February keeps the ice frozen through on more days than any other month, which is also when you will want your warmest layers.

This makes winter the best time for ice caving in Iceland. During the colder months, the caves are also at their most stunning, with the ice displaying vibrant shades of blue that create incredible patterns.

Since temperatures are at their coldest, wearing multiple insulating layers is essential. Think thermal base layers, fleece or wool mid-layers, and a windproof, waterproof shell to stay warm and dry during your adventure.

Winter in Iceland also means shorter days, so pay attention to the departure time when choosing your tour to maximize daylight hours and enhance your ice cave adventure. Our ice cave timing study found that departures between 10:45 AM and 1:00 PM are in daylight on every day of the season. Once you’ve sorted out what to wear, the next step is choosing the right ice cave tour.

Visiting Ice Caves in Summer in Iceland

If you're visiting Iceland in summer, you don't have to miss out. There's one natural ice cave that you can visit year-round, and that is the one in Katla ice cave in the Myrdalsjokull Glacier along the South Coast.

During summer, you'll witness more water runoff and a dynamic change in the cave's interior as the warmer temperatures alter the ice formations. It can be a beautiful and distinct experience compared to winter, especially as you'll have an easier time exploring the rest of Iceland during your summer visit.

While conditions are milder than in winter, the caves remain cold and damp. You may not need as many insulating layers as in winter, but warm base layers and a protective shell are still necessary.

No matter the season, the most important rule about what to wear on ice cave tours in Iceland is to layer effectively. This allows you to adjust to fluctuating temperatures while staying safe, warm, and comfortable inside the glacier.

These tours usually depart from the town of Vik, but summer ice cave adventures are also available from Reykjavík and other parts of Iceland. Here are some of the top options to help you plan your visit and experience these unique glaciers:

The Katla Ice Cave Tour from Vik: Take a guided three-hour adventure that includes a super jeep ride from Vik to the base of Myrdalsjokull Glacier. This year-round tour provides all necessary equipment and is suitable for all skill levels.
South Coast and Katla Ice Cave Super Jeep Trip from Reykjavik: Join a full-day guided tour that includes pick-up from Reykjavik in a modified super jeep and sightseeing at Seljalandsfoss and Skogafoss waterfalls.

Of course, if a real ice cave isn’t on your itinerary, you can still experience glaciers indoors at the Glacier and Ice Cave exhibition at the Perlan Museum. It's one of the top museums in Reykjavik, which includes an award-winning interactive exhibition space and a realistic recreation of an ice cave. You won’t have to worry about what to wear on an ice cave tour!

Perlan also has many other things to offer, as you can learn about Iceland's volcanoes and the hidden world of the Icelandic water. There is also the stunning Aurora Northern Lights Show, where you can experience the auroras any time of year, along with an amazing observation deck with the best views of the Capital Region!

Frequently asked questions

How cold does it get inside an ice cave in Iceland?

Inside Iceland's ice caves, the temperature usually hovers around 32 F (0 C) year-round. In winter, it can feel colder near the entrance, where icy winds blow through. Summer visits are a little milder but still cold and damp. That is why layered clothing, a waterproof shell, and insulated boots make all the difference.

Do ice cave tours give you the gear, or do I bring my own?

Tour operators provide the essential safety equipment, such as a helmet and crampons, on ice cave tours. You wear your own warm, waterproof clothing and hiking boots. Confirm with your operator what is included and whether you need to bring anything else. Most will list this clearly on the booking page.

Can I rent warm clothes for ice caving in Iceland?

Yes, you can rent the clothing you need for ice caving in Iceland. You can add hiking boots, a waterproof jacket, waterproof pants, and warm gloves to many bookings. This saves packing bulky gear for one activity. Reserve rentals in advance so your sizes are ready.

Do I need any special training for ice caving in Iceland?

Generally speaking, no special training is required for visiting an ice cave in Iceland, but a relatively good fitness level is recommended.

Is a heavy ski coat better than wearing multiple layers for ice caving in Iceland?

No, a heavy single jacket is not recommended for ice caving. Walking from the super jeep to the cave entrance requires physical effort that causes you to sweat. A heavy ski coat traps heat, leading to sweat build-up that chills you once you stand still inside the cave. A 3-layer system (thermal base, fleece/light down mid-layer, and waterproof outer shell) lets you release excess heat while walking and retain warmth while stationary.

Can I wear glasses inside an ice cave?

Yes, you can wear glasses in an ice cave, but you should apply anti-fog spray to your lenses or opt for contact lenses. Breathing through a neck gaiter or face mask inside a cold, humid ice cave directs warm moisture upward, which fogs up cold eyeglass lenses instantly.

What should I wear for an ice cave tour in Iceland?

For ice caving in Iceland, wear warm, waterproof layers and sturdy, high-ankle hiking boots. Start with a thermal base layer, add a fleece or wool mid-layer, and top it with a waterproof jacket and pants. Finish with a warm hat, waterproof gloves, and thick wool socks. See our full guide on what to pack for Iceland for a complete checklist.

Can I wear jeans on an ice cave tour in Iceland?

No, never wear jeans or denim on an ice cave tour. Denim soaks up water, then holds it against your skin. Once wet, it loses all warmth and can freeze in sub-zero temperatures, raising your risk of hypothermia. Wear synthetic hiking trousers or waterproof shell pants over thermal leggings instead.

Can I wear sneakers or regular boots for ice caving?

No, sneakers, running shoes, and soft boots are not allowed on ice caving tours. Crampons need rigid, high-ankle hiking boots to strap on safely. Soft footwear gives no ankle support on uneven ice, soaks through quickly, and lets crampon straps slip or dig in. Wear stiff-soled hiking boots that cover the ankle.

Can I rent hiking boots in Iceland?

Yes, you can rent proper hiking boots in Iceland. Many operators let you add boot rental during online booking, or you can pick them up at base camps near Jokulsarlon and Skaftafell. Expect a small fee, usually around 10 to 15 USD. Reserve your size ahead of time in peak season.

Do I need gloves for ice caving in Iceland?

Yes, always wear warm, waterproof gloves for ice caving. Choose insulated gloves rather than thin liners, and bring a spare pair in case one gets soaked. Keep them on for both the cave and the walk to it.

What socks should I wear for ice caving in Iceland?

Wear thick wool or synthetic hiking socks for ice caving, not cotton. Wool keeps your feet warm even if they get damp, while cotton stays cold and wet. Bring a spare pair in your bag for after the tour. Well-fitting socks also make rented boots more comfortable.

Can I wear a beanie under the helmet for ice caving in Iceland?

Yes, you can wear a beanie for ice caving, but avoid a pom-pom or large tassel stops a safety helmet from fitting properly. Helmets are mandatory inside every ice cave, so your hat must sit flush against your head. Wear a fitted, smooth wool or fleece beanie that covers your ears. Skip any bulky decorations on top.

What should I wear to look good in ice cave photos in Iceland?

Bright, high-contrast colors like red, orange, yellow, or hot pink look best in ice cave photos. Warm tones pop against the deep blue and black ice walls. Avoid navy, black, and dark grey, which blend into the shadows and turn you into a silhouette. A colorful jacket is an easy way to stand out.
