Two celestial seasons in one place
Most ski destinations offer you snow and, if you are lucky, a good view. Iceland offers something rarer. Across a single season running from March to mid-June, the Troll Peninsula (Tröllaskagi) in the far north of the country passes through two entirely different skies, each a genuine natural spectacle, and each a reason on its own to make the trip. Get your timing right and the heliskiing comes wrapped in one of the great celestial shows on earth.
In the early season, in March and April, the Arctic evenings are still dark, and on the right night the Northern Lights can ripple green and violet over the mountains. In the later season, across late May and June, that darkness has vanished entirely, replaced by the midnight sun and a daylight that barely ends, letting you ski late into luminous, golden Arctic evenings. One operation, one peninsula, two completely different experiences of the sky.
That is what makes Iceland worth planning around rather than simply turning up to. The skiing itself is superb from the first week to the last, but the wrapper changes profoundly as the weeks pass, and knowing which spectacle you are chasing is the single most useful decision you can make. This guide walks through both, honestly, so you can pick the week that gives you the once-in-a-lifetime moment you are really after. If you want the wider seasonal context first, our field note on the best time to go heliskiing sets the scene.
The Northern Lights early in the season
The aurora borealis is one of nature's most spellbinding sights: curtains and ribbons of green, sometimes pink and violet, shifting silently across the night sky. It happens when charged particles streaming from the sun collide with gases high in the Earth's atmosphere, and the effect is strongest in a band around the far north, precisely where the Troll Peninsula sits. North Iceland is genuinely well placed for it.
For a skier, the appeal is obvious. In March and April, early in the season, the evenings are still dark enough for the aurora to appear, so after a full day carving sea-to-summit lines you can step out into the Arctic night and, on a clear evening, watch the Northern Lights dance over the very mountains you skied. There are few finer ways to end a day on the snow, and few places where you can pair world-class heliskiing with a realistic chance of the aurora in the same trip.
It matters, though, to be completely honest about that word chance. The Northern Lights are never guaranteed, anywhere, and no one can promise you a sighting. Three things have to line up on the same night. You need darkness, which is why the effect fades as the season brightens; you need clear skies, so cloud does not curtain the show; and you need enough solar activity to drive the display in the first place. Any of those can be missing on a given evening, and often is.
The right way to hold this is as a magnificent possible bonus rather than a fixture on the itinerary. Book the early season, keep an eye on clear nights, and if the aurora appears it will be unforgettable. If it stays hidden behind cloud or a quiet sun, you will still have had an extraordinary week of skiing, which is the reason you came. Set your expectations that way and the Northern Lights can only ever delight you.
The midnight sun later in the season
At the other end of the season, the sky performs a completely opposite trick. As spring turns towards summer, the far-northern days stretch and stretch until, by late May and June, the darkness simply does not return. This is the midnight sun: the sun barely dips to the horizon and the evenings never truly end, bathing the mountains in a long, low, golden light for hours on end.
For heliskiing, this is transformative. There is no afternoon deadline closing in, no scramble to fit runs in before the light goes. Instead you can ski late into bright, luminous Arctic evenings, following the soft glow of a sun that refuses to set. The snow takes on warm colours, shadows lengthen beautifully across the slopes, and a run flown at what would elsewhere be bedtime feels utterly surreal in the best possible way.
The practical upside is just as real. The near-endless daylight of the midnight sun window means more flying time and longer, more relaxed skiing days than any winter operation could offer. Guides have the luxury of light on their side, and the whole rhythm of the day expands. Where the early season gives you a spectacle after skiing, the late season folds the spectacle into the skiing itself, every single run bathed in that impossible summer-Arctic light.
How the season shifts from dark to light
The magic of Iceland's season is that it is not two separate options bolted together but a single, continuous slide from dark to light. Understanding that arc helps you place your week exactly where you want it.
At the start, in March, the peninsula still feels wintry. Evenings are dark, the snowpack is cold, and the aurora has its best odds of the year. Through April the days lengthen noticeably, and while the Northern Lights window is closing, the dark hours are still there on clear nights. By May the balance has tipped: darkness is fading fast, the light is generous, and spring conditions settle in. Come late May and into June, the midnight sun has fully arrived, the nights are gone, and you ski in near-perpetual brightness right up to the season's mid-June close.
Think of it as one long dimmer switch turning from night towards endless day. The two spectacles sit at opposite ends of that dial, and everything in between is a graduated blend. That is why the specific week you choose matters so much: it decides which sky you get. The mechanics of how a heliski week is actually run stay consistent throughout, and our heliskiing guide explains those in full if you want the operational detail.
Choosing your end of the season
So which end should you book? The honest answer is that neither is better; they are simply different, and the right choice comes down to which experience you are travelling for. It helps to see the two windows side by side:
- Early season (March / April): Still-dark Arctic evenings that can bring the Northern Lights, a colder and more wintry feel underfoot, and the drama of skiing by day and, on clear nights, watching the aurora after. Best if the Northern Lights are your dream, and you accept that sightings are never guaranteed.
- Late season (late May / June): The midnight sun and near-endless daylight, skiing late into bright, glowing evenings, more flying time and long, unhurried days. Best if you want to ski beneath that unbroken summer-Arctic light and treat the long day itself as the spectacle.
A useful way to decide is to ask what memory you most want to carry home. If it is the image of standing beneath a dancing aurora after a day on the snow, aim for March or April, and go in with open, honest expectations about the sky. If it is the surreal feeling of dropping a line at what should be midnight, still in warm daylight, aim for late May or June. Groups that simply want the strongest, most reliable spectacle often lean late, because the midnight sun is a certainty in a way the aurora can never be. Either way, the sea-to-summit skiing between the two is world-class, so you are choosing a flavour of magic, not trading one down.
Sea-to-summit skiing beneath these skies
Whichever sky you choose, the skiing that unfolds beneath it is what makes the Troll Peninsula special in the first place. This is sea-to-summit terrain in the truest sense: the helicopter lifts you to summits of around 1,200 to 1,500 metres, and from there you ski a continuous, uninterrupted line all the way down to the Arctic Ocean glinting below. There are few sensations in skiing to match starting on a snowbound peak and finishing at the water's edge.
Viking Heliskiing has eleven zones across the region to draw on, so the guides can chase the best snow and conditions on any given day, and all of it is led by fully IFMGA/UIAGM-certified mountain guides. That combination of vast terrain and top-tier guiding is what lets the operation make the most of both ends of the season, whether that is a crisp March morning under a sky that may glow after dark, or a June evening run flown in the honeyed light of the midnight sun. If the concept is new to you, our explainer on what sea-to-summit skiing is goes deeper.
The point worth holding on to is that the celestial spectacle never comes at the expense of the skiing. Iceland does not offer pretty skies as compensation for thin runs; it offers genuinely exceptional descents that just happen to unfold under two of the most remarkable skies on the planet. The aurora and the midnight sun are the frame, but the sea-to-summit line is the picture.
The Siglufjörður base for aurora-watching
Where you stay shapes the celestial experience as much as when you go, and here Iceland is generous again. Viking Heliskiing is based in Siglufjörður, a beautiful former herring town tucked into a fjord at the northern edge of the peninsula, with guests staying at the 4-star Sigló Hótel right on the waterfront.
For the early season, this matters enormously. Siglufjörður is a small town in a remote northern setting, which means low light pollution and dark, open skies, exactly the conditions that give the Northern Lights their best stage. Step out from the hótel on a clear March or April evening and, if the aurora is active, you have a front-row seat over the fjord and the mountains, without the wash of city lights that spoils the show in more built-up places.
In the late season the same base plays a different role. When the midnight sun is up, the waterfront setting becomes a place to sit out in the endless evening light after skiing, watching that low golden sun linger over the water. Whether you are hoping for the aurora or basking in the midnight sun, the Siglufjörður base puts you in the ideal spot to enjoy whichever sky your chosen week delivers, in comfort and with the mountains on the doorstep.
What the long light makes possible
Beyond the spectacle itself, the changing light of the Iceland season quietly shapes the whole experience in ways worth appreciating. In the early weeks, the contrast between an active day of skiing and a still, dark evening gives the trip a satisfying rhythm, days full of movement bookended by quiet nights where the aurora might appear. It is a distinctly Arctic, distinctly wintry cadence.
As the season moves towards the midnight sun, that rhythm opens right up. The long light makes the days feel expansive rather than rationed, and there is a real sense of time stretching. Skiing is no longer confined to a narrow afternoon; the mountains stay lit and inviting far into the evening, and the pace becomes generous and unhurried. Many guests find the late-season light does something to the mood of the whole trip, an elemental, slightly dreamlike quality that comes from skiing when the sky says it should be night.
Both ends give you the essentials that make Iceland such a compelling place to ski in the first place: those sea-to-summit descents to the Arctic Ocean, the expert IFMGA/UIAGM guiding, the eleven zones of terrain and the comfort of the Sigló Hótel. The light simply changes the character of it all, from wintry and aurora-tinged to summery and sun-soaked, across the same magnificent peninsula. Whichever you pick, you are getting the full Iceland experience, just lit two very different ways.
Pick your season with Viking
Iceland's two celestial seasons are not a marketing flourish; they are a real, plannable choice that determines the sky you ski beneath. Book the early season and you point yourself at the Northern Lights over dark March and April evenings, chasing the aurora with open eyes and honest expectations. Book the late season and you step into the midnight sun, skiing late into bright June evenings under a light that never fades. Both are extraordinary, and both come attached to genuinely world-class sea-to-summit skiing.

Frequently asked questions
Can you see the Northern Lights while heliskiing in Iceland?
You can have the chance in the early part of the season. In March and April, North Iceland's evenings are still dark enough for the aurora to appear, so after a day's skiing you may see the Northern Lights over the mountains from the Siglufjörður base. It is important to be honest that sightings are never guaranteed. The aurora needs darkness, clear skies and enough solar activity all at once, and any of those can be missing on a given night. Treat it as a wonderful possible bonus rather than a certainty, and it never disappoints.
What is midnight sun skiing?
Midnight sun skiing means skiing in the near-endless daylight of the high Arctic in early summer, when the sun barely dips below the horizon and the evenings stay bright. On the Troll Peninsula in North Iceland, this lets you ski late into luminous Arctic evenings on Viking Heliskiing's sea-to-summit terrain, with long daylight opening up more flying time than a winter operation could ever offer. Instead of racing a fading afternoon, you ski in soft, low-angle golden light that can last for hours.
When can you ski under the midnight sun in Iceland?
The midnight sun arrives in the later part of the Iceland heliski season, roughly late May and June, when daylight becomes near-endless and the sun barely sets. Viking Heliskiing runs its season on the Troll Peninsula from March to mid-June, so booking towards the end of that window puts you squarely under the bright Arctic evenings. This is the time to ski late into glowing light and make the most of the long, generous flying days.
Should I book the early or late part of the Iceland season?
It depends on which spectacle you want. Book early, in March or April, for the chance of the Northern Lights in the still-dark evenings and a colder, more wintry feel. Book later, in late May or June, for the midnight sun, near-endless daylight and long, bright skiing into the evening. Both ends of Viking Heliskiing's March to mid-June season deliver superb sea-to-summit skiing, so the deciding factor is usually whether the aurora or the midnight sun matters more to you.
How do I book Northern Lights or midnight sun heliskiing in Iceland?
You book through Heliski Travel, the authorised booking agent for Viking Heliskiing on the Troll Peninsula in North Iceland. We can advise on which week best suits the experience you want, hold dates and confirm availability, all at exactly the same price as booking direct with Viking. The celestial windows, the Northern Lights weeks early and the midnight sun weeks later, tend to be the most popular, so it is worth getting in touch well in advance to secure your preferred dates.
