Glacier Trip Planning Guide: What to Wear, When to Go, and How to Book

The ho

Most glacier tour guides, including me, will tell you the ice itself is the easy part I recommend booking the Iceland South Coast Full Day Small-Group Tour From Reykjavik.. The hard part is everything you did or did not do in the week before the tour. The right boots, the wrong jeans, a booking made too early or too late, a flight that arrives at the wrong time of day, a camera battery that died on the bus. These are the things that turn a spectacular day into a forgettable one, and they are all things you control. The weather, the cave, the calving tide at the lagoon, those are not in your hands. Everything below is. Read it once before you book, then read it again the day before you pack.

What to wear on a glacier (and why you cannot wear jeans)

Let me start with the headline because the rest of the section depends on it. Do not wear jeans on a glacier hike. Not the "fashion" kind, not the "stretch" kind, not even the pair you wore on every hike you have ever done. The reason is not style, it is physics. Denim is cotton, cotton absorbs water, and once wet, denim loses almost all of its insulating value. On a glacier in summer, the morning is often around freezing, the wind off the ice finds every gap in your layers, and if you slip, sit, or kneel on wet ice, your jeans will soak through in under a minute. Then the rest of the day is a long, cold countdown. I have watched strong hikers reduced to shivering on the walk back to the van because they wore jeans. The guides will not turn you away for it, but they will be quietly worried about you, and you will be quietly miserable. Wear synthetic or merino base layers and a waterproof shell instead.

The full kit, in layers, looks like this. On your skin, a merino or synthetic long-sleeve and long johns. Cotton is the enemy here too, so even your underwear should not be the vacation souvenir kind. On top of that, a fleece or light down mid-layer that you can take off when the climb starts warming you up. On the outside, a waterproof and windproof shell jacket and shell pants, the kind with taped seams. These are the only two pieces worth buying properly if you do not already own them. On your hands, waterproof gloves with a thin liner underneath, because touching crampon straps with bare fingers in wind is how people end the day with white knuckles. On your head, a beanie that fits under a helmet and a buff or thin neck gaiter for the face. On your feet, waterproof hiking boots that rise above the ankle and have a stiff sole. The crampon strap needs an ankle to wrap around, and a soft trail-runner will not hold one. Most operators will refuse to fit crampons over a soft shoe, and rightly so.

The two items people forget are sun protection and a spare pair of dry socks. The sun off white ice is intense even in cloudy weather, and the guides will say this in the safety briefing because they have pulled sunburned faces off the glacier at the end of every clear season. Sunglasses with good UV coverage, ideally wraparound, and sunscreen on every bit of exposed skin, including the underside of your nose and the part line on your scalp if you part your hair. The spare socks go in a dry bag at the top of your pack, and you change into them the moment you get back to the van. That single habit is the difference between a comfortable transfer and a damp, cold bus ride back to Reykjavik or Franz Josef. If you take one piece of advice from this page, take the spare socks.

Best seasons: when to go for what

"Best season" is the wrong question, because the answer changes with what you actually want to see. Glacier travel is one of the rare kinds of tourism where the calendar is not a soft suggestion but a hard wall around certain experiences. I will give you the windows in plain language and then the reasoning, because if you understand the why, you can plan around a moving target.

Summer in Iceland, late May through early September. This is the high season, and for good reason. The South Coast is accessible, the glacier tongues like Solheimajokull are open for hiking, the South Coast combination tours run daily, and Jokulsarlon lagoon is boatable. The light is the magic part. Iceland in June does not really get dark. The sun dips below the horizon for an hour or two, the sky goes gold and pink, and then it comes back up. Photographers call this the midnight sun, and it gives you a twenty-hour working day if you want one. The trade is crowds, full parking lots at the famous waterfalls, and tours that book out two or three weeks ahead in July. If you are coming for the long light, come in late June. If you are coming for fewer people, early September is the under-appreciated sweet spot. The light is still long, the coach traffic has thinned, and most operators are still running full schedules.

Winter in Iceland, November through March. Winter is the only window for the natural blue ice caves under Vatnajokull, and that is the headline. Guides scout new caves each autumn because the old ones collapse or flood, and the ones they find are stable until spring. Outside that window the caves fill with meltwater and are unsafe to enter. So if the deep sapphire blue is the photo you came for, you are looking at a winter trip, The trade is short days, around five hours of usable light, the chance of road closures on the Ring Road east of Vik, and tours that get cancelled more often. Build slack into your itinerary. The South Coast waterfalls are dramatic in winter and the Northern Lights are a possible bonus if you stay three or four nights. Bring a serious winter coat, waterproof gloves you would trust at the North Pole, and a headlamp, because the day ends quickly and the meeting points are not always lit.

Shoulder seasons, April-May and October. These are the in-between months and they are underrated. The winter ice caves are sometimes still open in early April, the summer hiking season usually starts in mid-May, and the light is gorgeous. The risk is the weather can swing either way, with a winter storm in May or a balmy week in October. The reward is fewer people and lower prices on accommodation. If you can be flexible on dates, these are the months I would book if it were my own trip.

New Zealand, the West Coast glaciers. The seasons flip, because it is the Southern Hemisphere. Summer runs from about December through February, and that is when Fox and Franz Josef are most reliably flyable. Winter on the West Coast is the wet season, and heli-hikes get cancelled more often because the cloud sits on the icefall. If you are scheduling a New Zealand glacier trip, late January through early March is the safest bet. The Tasman Glacier near Mount Cook gets less rain than the West Coast because it sits in the rain shadow, and that is one of the reasons I rate it so highly in my New Zealand guide. Shoulder months in New Zealand, November and April, can also work, with the same caveat about weather flexibility.

Fitness requirements: who actually can do this

The honest answer is that the average reasonably fit adult can do almost every glacier tour on offer, but the average reasonably fit adult is not who the operators are worried about. The operators are worried about the people who book a glacier hike and then realize on the ice that they cannot walk on uneven ground for ninety minutes, or that they are not comfortable with the exposure on a narrow ridge. So here is a clear-eyed look at what each experience actually asks of your body.

A standard glacier hike, the kind on Solheimajokull or a tongue of Vatnajokull, asks for the ability to walk on uneven, sloped, occasionally slippery ground for about two hours, with breaks. You will be wearing crampons, which changes your gait, and the guide will set a slow pace because the group moves at the slowest person's speed. Most days on most tours, the fitness bar is "you can do a three-hour hike at home and not be destroyed by it." If you can do that, you are fine. If you have a knee injury that flares on stairs, think twice, because getting off the ice is always slower than getting on. The minimum age is usually eight or ten, depending on the operator, and the minimum weight is a real thing on heli-hikes because the helicopters have load limits.

An ice cave visit is generally easier on the body than a glacier hike. The walking is shorter, the surface is less technical, and the terrain is often flat inside the cave. The challenge is the cold and the duration in a confined space, not the cardio. If you are comfortable kneeling to crawl through a low entrance, you are fine. If you are not, tell the guide before you go in. They will find a route that suits you, because they would rather adjust the day than have to extract you from a tight spot.

The lagoon boat at Jokulsarlon and the scenic flights in New Zealand are the most accessible of the bunch. The boat is a seated experience with a guide doing the work. The flight is a seated experience with a pilot doing the work. If your fitness is the limiting factor, these are the experiences I point you toward without hesitation. You still get the ice in your view, and you do not need to be the kind of person who trains on the weekends to enjoy it.

Booking tips: when, where, and how to lock it in

The single most common booking mistake I see is leaving the popular tours to the day of. In July, a good South Coast combination tour can be sold out two or three weeks ahead. In winter, the same is true for the Crystal Blue Ice Cave, with the added problem that if your day gets cancelled for weather, the next available date may be a week away. Book early, then read the cancellation policy carefully, which I cover below.

A few smaller booking habits that pay off. Book the morning tour if you can. Mornings have calmer wind on the ice and the light is softer for photos. Avoid booking a glacier day on the day you arrive from a long-haul flight, because jet lag and crampons are a bad combination. Read the pickup details the night before, because some Reykjavik pickups are at bus stops, not hotels, and showing up at the wrong one in the morning is the kind of mistake that ends the day before it starts. And if you have two candidate days, book both as cancellable and pick the one with the better forecast forty-eight hours out, which leads me to the next section.

Cancellation policies: how to read the fine print

Glacier tour cancellation policies come in roughly three flavors, and you want to know which one you are buying before you pay. The first is "free cancellation up to twenty-four hours before." This is the gold standard, and the booking I would prefer every time. It lets you watch the weather and pivot without losing money. Most Viator listings show this clearly, and the operator's own sites usually match.

The second flavor is "free cancellation up to seventy-two hours before," with a non-refundable balance inside that window. This is fine if you are booking well in advance and you are confident about your dates, but it punishes last-minute changes. The third is "non-refundable," which I would only take if the price difference is large and the date is locked. Outside of that, the refundable option is almost always worth a few extra dollars for the flexibility.

Now, the part most people miss. There is operator cancellation, which is when the tour company calls the day because of weather, ice conditions, or guide availability. In that case, you get a full refund or a free rebooking, regardless of the policy above. And there is traveler cancellation, which is when you call. The policy above covers you. The two are different, and the weather cancellation is the more common reason travelers end up moving money around. A good operator will not push a tour that should not run. A great one will call you the evening before with a plan B. If you are booking direct with a small operator, this is a fair question to ask in advance: "If the weather closes the ice, what is the process?"

Camera tips for glacier photography

Glacier light is unlike anywhere else I photograph, and after eight seasons I at the still occasionally surprised by it. The ice is its own light source in a real sense, because the deep blue refracted out of the densest ice and the bright white of fresh snow together create a contrast ratio that will confuse any meter. Here is what I do, and what I tell the photographers I guide.

First, expose for the highlights. The blue of the ice is recoverable in post to a point, but blown-out snow is gone forever. If you are shooting in anything other than full manual, dial in negative exposure compensation of about two-thirds of a stop when the scene is mostly white. On a sunny day on a glacier tongue I will often shoot at ISO 100, f/8, and a shutter speed that puts me around 1/500. Those numbers are not a recipe, they are a starting point. Take a test shot, check the histogram, and adjust.

Second, bring a polarizing filter. It is the single most useful piece of glass for glacier work, because it cuts glare off the ice surface, deepens the blue of the crevasses, and lets you see into the meltwater channels that would otherwise be a sheet of white reflection. Rotate it slowly until the glare is at its minimum, then stop down half a stop to compensate for the lost light. A polarizer also slows your shutter speed, which is a feature in good light and a problem in low light, so take it off in cloudy conditions.

Third, take care of your gear. Cold kills batteries fast, so keep a spare in an inside pocket close to your body, not in the camera bag. When you come back into a warm van or cafe, leave the camera in the bag for twenty minutes before you open it, because condensation on a cold lens meeting warm air will fog the front element and can, over a long trip, encourage fungus inside the lens. A small microfiber cloth in a ziplock is the most valuable piece of cleaning kit you can carry.

Fourth, and most important, take the phone shot too. I have a full kit, I work professionally, and I still pull out my phone for at least a third of the day on a glacier hike. The phone is in your pocket, it is already focused, and the best photo of the trip is often the candid frame of your partner on the ice looking at something you cannot see. Do not let the gear get in the way of the memory. The postcard shot is for the album, the candid shot is for the rest of your life.

The pre-departure checklist I actually use

The night before every glacier day, I run through the same short list, and it is the one I give to friends and clients. It is not fancy. It is just the things that, if forgotten, ruin the day.

• Waterproof jacket and pants, packed, not still on a chair drying from last week's rain.
• Two pairs of gloves, one liner, one shell. The liner is in a pocket where you can find it.
• Two pairs of socks in a dry bag at the top of the pack. Dry on, dry in the bag, dry on again.
• Waterproof hiking boots broken in. New boots on a glacier day is how blisters end the day.
• Beanie, buff, sunglasses, sunscreen. Every one. The sun off ice is no joke.
• Phone charged, camera battery charged, spare battery warm in an inside pocket.
• Pickup time, pickup point, and the operator's phone number written down or screenshotted, not just bookmarked.
• A cancellation plan. If the tour is called, do you rebook tomorrow, swap to a different tour, or refund?

That is the whole list. If you can tick all eight boxes the night before, the day is almost always good, and when the weather is bad, you are at least comfortable while you wait it out. The glacier does not care about your preparation, but your body and your camera absolutely do.

The final word

I will end where I began. The ice is the easy part. The week before is the part that decides whether the day on the glacier is the highlight of your trip or the day you wish you had spent in a hot spring. Wear the right layers, book the refundable option, leave the jeans at the hotel, and take the phone shot. Do that, and the ice will do the rest.
