What to Pack for a Northern Lights Tour in Finnish Lapland

Packing correctly is one of the most decisive factors in whether your Finnish Lapland winter trip is magical or miserable. The difference between standing comfortably under a blazing aurora at −22°C and retreating to the minibus after fifteen minutes comes down almost entirely to what you wore out of the door. This guide is built from eight winters of running aurora tours in Ruka — it reflects what genuinely works in the field, not generic cold-weather advice.

The temperatures in Ruka and Kuusamo range from roughly −5°C in early September to −30°C on the coldest clear nights of January and February. Those coldest nights, frustratingly, are also often the clearest and most aurora-active. Dress for them.

Note: We provide all guests with an insulated full-body thermal oversuit, outer boots rated to −40°C, and outer mittens at no extra charge. The items below are what you need to bring yourself — particularly base and mid layers, which cannot be shared.

Clothing: The Three-Layer System

The layering system is not a suggestion — it is the single most important principle for cold-weather comfort. Each layer serves a specific purpose, and skipping one breaks the chain.

Base Layer

Your base layer sits directly against your skin. Its job is to wick sweat away so you stay dry, because wet skin loses heat twenty times faster than dry skin. The best options are:

• Merino wool — naturally odour-resistant, warm even when damp, and comfortable against sensitive skin. A 200–250 gsm weight is ideal for Finnish winter temperatures. Brands like Icebreaker, Smartwool, and Devold are reliable.
• Thermal synthetic — polyester-based fabrics (Polartec Baselayer, Patagonia Capilene) wick moisture faster than merino and dry quicker, though they hold odour more readily on multi-day trips.

Avoid cotton entirely. Cotton absorbs moisture and holds it against your skin, making you progressively colder as the night wears on. Even a cotton T-shirt under merino wool creates a problem. Bring top and bottoms — thermal leggings under your trousers make an enormous difference.

Mid Layer

The mid layer traps warm air close to your body. On an aurora tour you will be standing still for extended periods — a very different thermal challenge from skiing or hiking, where activity generates heat. Choose:

• Fleece jacket (300 gsm or heavier) — Patagonia R2, Arc'teryx Covert, or any heavyweight fleece. A full-zip allows ventilation during transfers.
• Down or synthetic-insulated jacket — a puffer jacket over your fleece adds significant warmth. Down is lighter and packable but loses insulation when wet; synthetic insulation (PrimaLoft, Thermoball) performs better in damp conditions.

On particularly cold nights (below −20°C), wearing both a fleece and a puffer as your mid layers before the provided oversuit is not excessive — it is wise.

Outer Layer

We supply the outer layer (insulated oversuit) on our tours. If you are doing any independent activity outside of a tour — walking to a viewpoint, exploring after dinner — you need your own windproof and waterproof shell jacket and trousers. Gore-Tex or equivalent. No wind resistance means no warmth.

Footwear: Rated to −30°C is Non-Negotiable

Your feet are in contact with frozen ground for hours at a time. Heat loss through conduction is severe, and once your feet are cold, no amount of wool socks will recover the situation. You need purpose-built Arctic winter boots — not hiking boots, not fashion snow boots, not insulated trainers.

Look for boots rated to at least −30°C. Trusted options include Sorel Caribou, Baffin Impact, Kamik Momentum, and Muck Boot Arctic Ice. The sole should be rubber-based for grip on ice and compacted snow.

Pair your boots with merino wool socks — at least 20% wool content, ideally 60% or higher. A medium-weight hiking sock (not a thin dress sock) works best. Bring two or three spare pairs, as they are the first item to absorb moisture from condensation inside the boot during long cold nights.

Hands and Head

Your extremities — hands, ears, nose, and the back of your neck — lose heat disproportionately quickly. Protecting them is not optional at Arctic temperatures.

Hands

A two-glove system works best:

• Thin liner gloves — merino or silk liner gloves that you keep on while operating your camera, phone, or tripod. They allow enough dexterity to adjust settings without exposing bare skin to the air.
• Outer mittens — thick, insulated, ideally waterproof-shelled mittens that go over the liner gloves. We provide outer mittens, but your liner gloves are personal. Mittens retain more heat than fingered gloves because your fingers share warmth.

Head and Face

• Wool or fleece hat — must cover your ears entirely. A hat that sits above your ears is only slightly better than nothing at −20°C.
• Balaclava — essential for January and February, strongly recommended for December. A thin merino balaclava worn under your hat covers your cheeks, nose, and chin. In January, exposed skin can experience frostbite in under 30 minutes at −25°C with any wind.
• Neck gaiter or snood — covers the gap between your jacket collar and your hat, which is a significant heat-loss point during the walk from the vehicle to the viewing spot.

Camera Gear

The Northern Lights are one of the most challenging and rewarding photography subjects in nature. Having the right gear — and preparing it correctly — makes the difference between coming home with a single blurry green smear and a set of images that do justice to what you witnessed.

Essential Camera Equipment

• Camera body — any mirrorless or DSLR with full manual control. A full-frame sensor performs significantly better at high ISO than a crop sensor, but an APS-C body with a fast lens still produces excellent results.
• Wide-angle lens — 14mm–24mm on full-frame (or equivalent on crop). An aperture of f/2.8 or faster is important; f/1.8 or f/2 is even better. The wider the lens, the more sky you capture in one frame.
• Sturdy tripod — non-negotiable. Exposures of 4–25 seconds mean any camera movement becomes a blur. Carbon-fibre tripods are lighter; aluminium works fine but becomes brittle in extreme cold. Extend the legs with neoprene covers to avoid metal sticking to bare skin.
• Spare batteries (minimum 2 extras) — cold kills batteries. A battery that shows 80% charge indoors may read empty after 20 minutes at −20°C. Keep spare batteries in your inner jacket pocket, against your body heat, and swap them in when the active battery dies. Rotate them back to warm rather than discarding.
• Large memory cards — shooting in RAW format (which you should) uses 20–50MB per image. A 128GB card gives you comfortable headroom. Bring two in case of failure.
• Lens cloth — breath condenses on cold glass surfaces. Keep a microfibre lens cloth in an accessible inner pocket. Never clean a cold lens with a wet cloth — the moisture freezes.
• Remote shutter release or intervalometer — allows you to trigger the shutter without touching the camera and causing vibration. A cable release or Bluetooth remote works. A 2-second self-timer is a reasonable alternative.

Preparing Your Camera for the Cold

When bringing a cold camera back into a warm room, do not open the memory card slot or battery compartment immediately. Condensation will form inside the camera body and potentially damage the sensor. Place the camera in a sealed plastic bag before entering a warm building, and let it acclimatise for 30–60 minutes before opening any ports.

Skincare and Health

The Arctic air is exceptionally dry, especially indoors where heating systems run at full power. Many guests underestimate how much this affects comfort over a multi-night trip.

• Lip balm with SPF — cold dry air cracks lips within a day. Keep a stick in your jacket pocket and apply every time you go outside. UV reflection off snow is significant even in winter.
• Thick moisturiser or barrier cream — for cheeks, nose, and hands. Facial skin exposed to cold air and wind dries and chaps rapidly. Apply before going out, not just after.
• Eye drops (preservative-free saline) — indoor heating dries out eyes significantly, particularly for contact lens wearers. Many guests find their eyes are irritated within 24 hours of arriving in Finnish Lapland due to the low humidity. Eye drops provide immediate relief.
• Any prescription medication — bring more than you need. Delays are possible in remote Finnish Lapland, and pharmacies in Ruka stock common over-the-counter items but not specialist prescriptions. Pack medication in your carry-on, never in checked luggage.
• Antihistamines and pain relief — useful for altitude adjustment headaches (Ruka is relatively flat but air pressure changes from flights still affect some guests) and as a general precaution.

Tech and Charging

• Power bank (20,000 mAh or higher) — cold also drains phone batteries. A high-capacity power bank kept in your inner jacket pocket allows you to keep your phone alive through a full aurora hunt. Anker, Mophie, and Zendure all produce reliable units.
• USB-C cable and charging cables for all devices — always more useful than you expect.
• Travel power adapter (Type F, Schuko) — Finland uses two-round-pin Type F (Schuko) plugs at 230V / 50Hz. UK travellers need a UK-to-Type-F adapter. US travellers need a US-to-Type-F adapter. Most modern electronics are dual-voltage (100–240V) — check the label on each charger before using.
• Camera battery charger — an obvious inclusion that is surprisingly easy to forget. Check it fits the Type F adapter.

Documents and Essentials

• Passport or national ID card — Finland is in the Schengen Area. EU/EEA citizens can travel with their ID card; all others need a valid passport and any required visa.
• Travel insurance documents — print a physical copy and store a digital version on your phone. Ensure the policy covers winter activities, medical evacuation, and trip cancellation. This is not optional — remote Arctic medical care can be expensive for uninsured visitors.
• Tour booking confirmation — a screenshot or PDF of your booking confirmation with our contact number.
• Emergency contact information — including the number for the Finnish general emergency services: 112.

The Complete Packing Checklist

What You Do Not Need to Bring

To save space and weight: you do not need a sleeping bag (accommodation in Ruka is well-heated), snowshoes (we handle transport by vehicle to viewing spots), or crampons (ice cleats are useful but not essential — we guide you safely). A heavy suitcase-sized bag is unnecessary; a mid-size 50–70 litre bag handles everything on this list comfortably.
