The Andes: heliskiing in the Northern summer
For skiers in Europe and North America, midsummer is normally the dead zone. The lifts have long since closed, the glaciers are thin, and the next real winter is a distant prospect. The Andes change that. Draped down the western edge of South America, deep in the Southern Hemisphere, these mountains run on the opposite calendar to ours: while the Northern resorts turn to hiking trails, the high Andes are cold, snowbound and skiing. This inversion of seasons is the whole point — it is what makes South America heliski trips one of the two great answers to the question every committed skier eventually asks: where can I ski powder in July?
The other answer is New Zealand, and together the two make up the Southern-hemisphere pair. The Andes' distinguishing note is scale. This is enormous, high-altitude mountain country — a spine of volcanic cones and alpine peaks that dwarfs most of what Northern skiers are used to. If you want to turn one winter a year into two, and you are drawn to big, wild, high terrain, Andes heliskiing deserves a serious look. For a broader look at where the year takes keen skiers, our best time to go heliskiing guide maps the full calendar.
Where you heliski: Chile's central Andes and Argentina
Southern-hemisphere heliskiing in South America concentrates in two countries that share the range along their long border: Chile to the west and Argentina to the east. Each has its own focal areas, and each offers a different flavour of the same great cordillera.
In Chile, the heart of the action is the central Andes near Santiago. This is the country's most accessible high-mountain region, within reach of the capital and its international airport, and home to the well-known ski areas around Portillo and Valle Nevado. The terrain here is high, dry and dramatic, and its proximity to a major city makes it one of the more straightforward Andes regions to reach for heliskiing Chile.
In Argentina, the focal areas sit further south and further inland. Bariloche, set among the lakes and peaks of northern Patagonia, is the best-known base, surrounded by classic Andean scenery. The wider Patagonia region stretches south into some of the wildest mountain country on the continent. Further north, Las Leñas is a byword among adventurous skiers for big off-piste terrain. Together these give heliskiing Argentina real variety, from lake-district beauty to raw Patagonian scale.
The terrain: high-altitude volcanic and alpine country
The defining feature of the Andes is size and elevation. This is big, high-altitude terrain — a landscape of volcanic cones, glaciated peaks and vast alpine faces that reaches heights well beyond most European or New Zealand skiing. That scale shapes the whole experience.
- Volcanic character. Much of the range is volcanic, and skiing the flanks of towering cones is part of the Andes' distinctive appeal. The lines are long, open and unmistakably South American.
- High alpine faces. Above the tree line the Andes offer sweeping, exposed faces and bowls, with the sheer vertical scale that draws big-mountain skiers south.
- Glaciated high country. The higher peaks carry permanent ice, holding snow later into the season and offering the most serious, committing descents.
- Wild remoteness. Particularly in Patagonia, the terrain feels genuinely remote, with a sense of space and isolation that is hard to find in more developed heliski destinations.
The trade-off for all that grandeur is exposure — to altitude, to weather, and to the fast-changing conditions that come with such large, high mountains. Reading the terrain well is central to a good Andes trip, which is why experienced guiding and sensible planning matter here as much as anywhere.
Snow and season: July to October, and variable
The Andes heliski season runs broadly from July to September or October, tracking the Southern-hemisphere winter. Conditions typically build through July, reach their fullest through August, and can hold into the spring in the higher, glaciated terrain where snow lingers longest. For a Northern-hemisphere skier, this is a near-perfect overlay onto the months when home is unskiable.
Honesty serves you better than hype, though, and Andes snow is variable. The range spans a huge distance and a wide spread of climates, and conditions can swing from deep, dry powder to wind-affected surfaces to spring-like snow within a short span. Storms and clear windows come and go, and the weather in high mountains this size is never fully predictable. The practical response is flexibility: skiers who build spare days into their plans, keep dates loose, and treat heliskiing as opportunistic — going when the window opens rather than forcing a fixed slot — consistently have the best trips. Come with patience, and the Andes reward you generously.
The altitude factor: plan for the height
What sets the Andes apart from almost every other heliski destination is altitude. These mountains reach heights that Northern skiers rarely encounter, and thinner air has real, practical effects: breathing is harder, energy drains faster, and recovery between runs takes longer. It is not a reason to be put off, but it is a reason to plan sensibly.
A good approach treats the first days as a build-up rather than a peak, allows time to acclimatise before the most demanding skiing, and leans on fitness, hydration and rest to cope with the height. Skiers who arrive well-conditioned and give their bodies time to adjust generally enjoy the Andes far more than those who fly in and expect to perform at full tilt immediately. Our heliskiing in New Zealand field note describes a gentler Southern-hemisphere option at lower elevation, and the contrast is instructive: the Andes ask more of your body, and reward that preparation with terrain on a scale New Zealand cannot match.
The character of an Andes trip
An Andes heliski trip has a character all its own. This is big-mountain skiing in a wild, high, dramatic setting, with a strong sense of adventure and remoteness — particularly in Patagonia, where the mountains feel genuinely far from the everyday world. It is a destination for skiers who want scale and a real expedition feel rather than a tidy, resort-adjacent day out.
Its greatest single virtue for Northern skiers is off-season appeal. When the home hills are green, the Andes are prime, and that timing is priceless to anyone who cannot bear a summer without turns. Just as important, the Andes make superb sense as part of a wider journey. South America is a rich, rewarding continent, and few travellers cross the world for skiing alone. Building your heli days into a broader trip — Patagonia's landscapes, Chilean and Argentine culture, wine country, the sheer variety of the continent — turns the long flight into real value.

Who Andes heliskiing suits
Heliskiing is for confident skiers, and the Andes are no exception — in fact they ask a little more. You should be a solid intermediate or advanced skier, comfortable and in control on ungroomed, off-piste snow of varying quality. This is not a place to learn; the terrain, the altitude, the remoteness and the cost all assume you can already ski a real mountain.
Beyond ability, the Andes reward a particular temperament. They suit skiers who:
- Are drawn to big terrain. If scale, height and wildness excite you more than convenience, the Andes deliver.
- Value the off-season. Anyone unwilling to let summer stop their skiing has an obvious reason to look south.
- Enjoy a wider adventure. Travellers who want to fold skiing into a broader South America trip get the most from the distance.
- Prepare properly. Fit, adaptable skiers who respect the altitude and the variable snow have the best time.
The Andes vs New Zealand: the two Southern options
The Andes and New Zealand are the two main Southern-hemisphere heliski choices, and they answer the same calendar question in different ways. Both run through the Northern summer, so both solve the off-season. Where they diverge is character. New Zealand offers open, glaciated bowls at more moderate elevation, a flexible day-based format from comfortable resort bases, and easy folding into a wider adventure holiday. The Andes counter with far greater scale and altitude — bigger, higher, wilder terrain, especially in Patagonia, with the volcanic drama that only South America provides.
Neither is simply better. New Zealand tends to be the gentler introduction to Southern-hemisphere skiing; the Andes reward those who want size and a stronger expedition feel and are prepared for the height. Many keen skiers try both over the years, treating them as two distinct flavours of the same summer opportunity.
The Andes vs Iceland: two halves of one ski year
It would be easy, and wrong, to frame the Andes and Iceland as rivals. They are complementary, and the clearest way to see that is the calendar. The Andes fill the Northern summer, roughly July to September or October. Iceland's Viking Heliskiing, which we book as an authorised agent, runs March to mid-June — the Northern spring. Together they cover a large stretch of the year that home resorts cannot.
The two also feel entirely different. The Andes are about high-altitude, volcanic, big-mountain terrain on a remote Southern-hemisphere scale. Iceland's signature is sea-to-summit descent — Viking's runs on the Troll Peninsula (Tröllaskagi) in North Iceland drop roughly 1,200 to 1,500 metres from ridgeline all the way to the Arctic Ocean, across eleven guided zones with IFMGA/UIAGM guides, from a four-star base at the Sigló Hótel in Siglufjörður. One is a summer answer, the other a spring one. Many committed skiers simply do both. If you are weighing destinations across the whole year, our best time to go heliskiing field note puts them in context.
How to plan and book your trip
Planning an Andes heliski trip comes down to a few sensible moves. Choose your country and region — Chile's central Andes near Santiago for accessibility and dry high terrain, or Argentina's Bariloche, Patagonia and Las Leñas for scenery, scale and wildness. Target the July to September or October window, and build in spare days so a run of bad weather does not sink the whole trip. Respect the altitude, arrive fit and allow time to acclimatise. Be honest about your ability, since the terrain assumes competent off-piste skiing. And treat the heliskiing as part of a wider South America itinerary rather than a rigid, standalone booking.
The Andes suit self-directed travellers who like to assemble their own big adventure. If, on the other hand, you want the simplicity of a single guaranteed week with everything arranged — guides, helicopter, four-star base and a set programme of vertical — that is exactly where an Iceland Viking week shines, and where we can help directly.
Complete your ski year in Iceland
The Andes are a superb, honest answer for skiing in the Northern summer, and we will always tell you so. When the calendar swings back to the Northern spring, though, the natural next chapter is Iceland. As an authorised booking agent for Viking Heliskiing, Heliski Travel arranges your week at the same price as booking direct — sea-to-summit descents to the Arctic Ocean, IFMGA guides and the Sigló Hótel, with weeks running from around €3,490 to €82,990 across three-, four- and five-day formats by guaranteed vertical feet. Do the Andes in your summer and Iceland in the spring, and you have built a fuller year of skiing. When you are ready to plan the Iceland half, get in touch and we will make it simple.
Frequently asked questions
Can you heliski in South America?
Yes. The Andes offer Southern-hemisphere heliskiing during the Northern summer, with Chile and Argentina as the two focal countries. Because their winter falls when Europe and North America are unskiable, the Andes are one of the standout ways for Northern-hemisphere skiers to keep skiing through their off-season, alongside New Zealand.
When is the Andes ski season?
The Andes heliski season runs broadly from July to September or October, tracking the Southern-hemisphere winter. Conditions build through July and August, and higher, glaciated terrain can hold snow later into the spring. Snow and weather in the Andes are variable, so keeping flexible dates and building in spare days improves your odds of good flying.
Where can you heliski in Chile and Argentina?
In Chile the focus is the central Andes near Santiago, in the regions around Portillo and Valle Nevado. In Argentina the focal areas are Bariloche and the wider Patagonia region, along with Las Leñas further north. Both countries offer big, high-altitude volcanic and alpine terrain, and each pairs naturally with a broader South America trip.
Is heliskiing in the Andes difficult because of the altitude?
Altitude is a genuine factor in the Andes, which reach far higher than most European or New Zealand terrain. Thinner air can affect breathing, energy and recovery, so a sensible plan allows time to acclimatise, prioritises fitness and hydration, and treats the first days as a build-up. Confident off-piste ability matters as much as altitude readiness.
How does the Andes compare with heliskiing in Iceland?
They are complementary rather than competing, because they run in opposite seasons. The Andes fill the Northern summer, roughly July to September or October, while Iceland's Viking Heliskiing operates March to mid-June, the Northern spring, with sea-to-summit descents of around 1,200 to 1,500 metres to the Arctic Ocean. Many keen skiers do the Andes in their summer and Iceland in the spring for a fuller year of skiing.
