Here is what to do here in winter, when to come, and how to make the most of it.
1. See the northern lights over a frozen sea
Oulu sits far enough north that the aurora is a regular winter visitor, roughly from September to March. What makes it special here is the setting: wide, dark horizons over the frozen sea, only minutes from town, with no long wilderness transfer needed.
You can try your luck on your own from the beach at Nallikari, or join a guided tour. We run an Arctic Northern Lights Camp at a heated tent on the sea ice, with a campfire and hot drinks while you watch the sky, and an Aurora Hunting Safari that travels by minibus to wherever the skies are clearest that night.

2. Go ice fishing on the Gulf of Bothnia
Ice fishing is a genuine Finnish winter tradition, and the sea off Oulu is unusually rich in fish. You drill your own hole through the ice, drop a line, and wait in the enormous quiet of the Arctic morning. We use a sonar fish finder, so you can actually see the fish below reacting to your lure.
No experience is needed, thermal clothing is included, and there is a heated tent on the ice if the wind picks up. It is our most popular winter experience for a reason.

3. Cycle on the frozen sea
Yes, you really can ride a bicycle on the Baltic Sea. Fatbikes have oversized, low-pressure tyres that float over snow and ice, and when conditions allow we ride straight out onto the frozen sea, with the Oulu skyline on one side and open white horizon on the other. When the snow is too deep for the ice, we take the snowy forest trails of Nallikari and Hietasaari instead.
It requires no special skill, just the ability to ride a bike, and it is easily the most surreal photo you will take on your trip.

4. Sauna on the ice, then swim in it
A wood-heated sauna tent, pitched directly on the frozen sea, with an ice hole opened beside it in shallow, sandy-bottomed water. Sit in the heat, look out over the white seascape, and if you want the full Nordic experience, take the plunge.
Nobody is required to swim. Plenty of guests just watch, warm up and enjoy the steam. But those who do try it tend to talk about it for years.

5. Walk on the sea with snowshoes
Snowshoeing is the gentlest way to experience the frozen sea. The route is flat, suitable for beginners and families, and leads across the white ice and into the snowy forests and parklands of Hietasaari. Along the way we build a campfire directly on the sea ice and brew coffee, which is about as local as a winter afternoon gets.

6. Meet reindeer just outside the city
You do not need to go to Lapland to meet reindeer. A short drive from Oulu there is a working reindeer farm where you can feed and photograph the herd, hear about reindeer herding from the people who do it, and warm up with hot drinks and pastries by an open fire inside a traditional wooden hut.

7. Enjoy the city, too
This is the part most Arctic destinations cannot offer. Oulu is a proper city with a market square and market hall, museums, galleries, restaurants and cafés, and as European Capital of Culture 2026 it has an unusually full events calendar this year. You can be out on the ice in the morning and at an exhibition or a long dinner in the evening.
When is the best time to visit Oulu in winter?
December: Christmas atmosphere, dark skies, and, unlike Lapland, availability. Lapland sells out months ahead for the holidays. Oulu often does not.
January and February: the deepest winter. Thick sea ice, snow, and full winter programme.
March: arguably the best month of all. Strong aurora activity, clearer skies, more daylight and still solid ice.
Our winter season runs from 22 December to 31 March, with aurora tours available from October.
What to know before you come
Getting here is easy. Oulu Airport is a short ride from the centre, and the train from Helsinki takes around 5.5 hours.

You do not need your own gear. Thermal overalls, boots, gloves and hats are included on our winter tours. Bring warm layers to wear underneath.
No experience required. Every winter activity above is beginner-friendly and guided in English.
Frequently asked questions
Is Oulu a good winter destination?
Yes. You get aurora, a frozen sea, reindeer, ice fishing and sauna culture, plus a real city with restaurants and museums, all in one place and with easy access.
Can you see the northern lights in Oulu?
Yes, regularly between roughly September and March on dark, clear nights. Sightings can never be guaranteed anywhere, but the conditions here are excellent.
Is Oulu better than Lapland?
It depends on what you want. Lapland suits remote wilderness resorts and multi-day expeditions. Oulu suits travellers who want Arctic experiences with easier access, lower cost, fewer crowds and a city on the doorstep.
How cold does it get?
Winter temperatures typically range from around -5°C to -20°C. With proper thermal clothing, which we provide, it is very comfortable.
