What to Wear to an Ice Cave Tour in Iceland
Planning your cave day?Every tour here has free cancellation up to 24 hours before departure — reserve a spot now, decide later. Winter crystal-cave dates are the only ones that regularly book out.
Check availabilityThe boot requirement: non-negotiable
You need real waterproof hiking boots. Crampons strap onto hiking boot soles; they don’t work on sneakers or street shoes. The cave floor is ice, there are crevasses nearby, and traction matters. If you don’t own boots, the crystal tour can lend a pair for the day. Katla and Langjökull tours don’t advertise loaners, but ask at the booking desk — they often have pairs if you’re their shoe size.
Layers: waterproof is the keyword
Inside the cave it’s about 0°C, even in August. Outside on the glacier it’s colder. Wear a waterproof outer shell (jacket and trousers) and warm layers underneath — fleece, merino wool, or thermal underwear. Avoid cotton; it traps cold when wet. One reviewer put it simply: "warm waterproof layers" — that’s the formula.
Hat and gloves: cold hands kill the experience
The cave is lit by helmet lamps and your guide, and your hands get cold fast. Wear gloves inside the cave. A wool or fleece hat is essential for the drive and walking. Cotton hats are useless in the wet.
The jeans problem
Jeans soak with glacier water and rain. Once wet, denim holds the cold and you’ll be shivering for the rest of the day. Waterproof trousers (or at least water-resistant ones) are the difference between "I’m a bit damp" and "I’m freezing." Reviewers on summer Katla tours mention: "bring proper waterproofs" every time someone shows up in jeans.
What the tours provide
Helmets and crampons are always included. Gloves, extra socks, and sometimes boot covers come with some tours. The crystal tour explicitly lends boots if you need them. Most operators also provide a waterproof suit or overtrousers on request, though bringing your own is safer.
Rent or borrow hiking boots if you don’t own them (most Reykjavík outdoor shops have them). Once you have boots, a waterproof jacket, and gloves, the rest is just warmth. Over-pack layers; you can leave a fleece in the super jeep while you’re in the cave and put it back on after.
Frequently asked questions
What shoes should I wear to an ice cave tour?
Waterproof hiking boots. Crampons strap onto boot soles only. Sneakers don’t work. If you don’t have boots, the crystal tour can lend a pair; ask other tours at booking.
Can I wear jeans to an ice cave?
Technically yes, but don’t. Jeans soak with meltwater and rain and hold the cold. Waterproof or water-resistant trousers are the difference between damp and miserable.
Is it warm inside the cave?
No. About 0°C year-round, even in August. Wear warm layers and waterproof. Hat and gloves are critical.
Does the tour provide gloves and hats?
Some tours include gloves and extra socks; most provide helmets and crampons. Bring your own hat and gloves to be safe. Wool or fleece, never cotton.
What if I don't have waterproof gear?
Rent a waterproof jacket and trousers in Reykjavík if needed. Hiking boot rental shops usually have waterproof kits. The cave stay is 30–45 minutes; the rest is the ride and approach.
