Kiilopää, Finland

Prepare for your last commit

Codefreeze is an unconference with very little structure. Actually, it’s not a conference at all. Codefreeze is a time and place for software craftspeople to meet. We would like to have likeminded people to gather in one place and have long conversations about our craft over a drink. And to practice our coding skills.

While most sessions happen from Monday to Friday, participants typically spend a full week in Kiilopää to enjoy the amazing winter nature and activities.

Did we mention that this place is above the arctic circle? Which is pretty cool. Or freezingly cold actually.

Past Events

Since 2015, Codefreeze has happened every year around January. In 2019 we had about 35 participants plus their family and friends, 40 in 2020, 50 participants in 2023 and around 80 in 2024.

Sessions

To get an idea of what happens at Codefreeze, you can find the conference schedules on Wekan (2025) and Trello (until 2024). Most Codefreeze topics (green) have additional information in links in the cards.

The Trello board is also used for coordinating travel arrangements and planning the next Codefreeze, so it’s good to check it out in advance.

Why?

Winter? Really?

Have you ever been coding under the northern lights? Or in a Lapp daylight? Early-mid February is one of the best times to see northern lights in action. It turn out that during our stay in 2024, we have a new moon - which means that if we get lucky with the auroras, there is less other light sources (moon) and the auroras can be seen as more intensive. That also means that the evenings will be way darker than during full moon (like 2023)

We know it might be rather cold. Temperatures down to -25°C are normal at the time of the year. For some clothing tips, see the FAQ.

Smoke sauna?

Being in Lapland in the winter, and one of the most important things is to have a decent sauna. And we do. There’s a big enough smoke sauna to have probably up to 25 programmers. And possibility for winter swimming on a relaxing little stream.

Want to relax a bit while coding?

Luckily, nature is at the core of Kiilopää. And not only that, Kiilopää provides daily trips to nearby fells guided by experienced nature guides. For example, there’s a snow shoe trip on Wednesday morning.

Kiilopää: a magical place in Lapland

Kiilopää Fell Center in Lapland is an ideal place to get in touch with the Nordic wilderness. At Kiilopää you can conquer a fell, dip into an ice-cold lake, and ski under the Northern Lights. Or you can just sit back and enjoy the surrounding natural beauty, sense the arctic peace and quiet, and listen to exotic Lapland stories by the fireplace.

Kiilopää is owned by Suomen Latu, the Outdoor Association of Finland. Suomen Latu is a promoter of outdoor activities, an expert in hiking and an organisation which is open to all. The main objective of Suomen Latu has always been to increase Finnish people’s interest in exercise as well as developing possibilities for outdoor, conditioning and recreational exercise. Nowadays guarding everyman’s right has become more and more important.

For more information see the official Kiilopää web site.

Activities

Have you done The Dip?

The Sauna World of Kiilopää is called Kuurakaltio. There are two electric saunas with dressing rooms and showers, as well as a traditional Finnish smoke sauna. There are separate sauna facilities for men and women.

Have you ever been winter swimming? It is an experience when the air temperature is around -20 ºC while the water is -1 ºC. You might want to dip into the refreshing waters of Kiilopuro fell brook. And if feeling really crazy, why not to take a fresh start in the morning?

During Codefreeze, the smoke sauna is heated on some weekdays (check from Kiilopää), and on Monday we have a private sauna for the evening.

More information about the smoke sauna in Kiilopää.

Spending some time at Kiilopää?

As folks found out on Codefreeze 2015, the scenery is beautiful and there are a lot of interesting things to do, outside the realms of talking software. Suomen Latu Kiilopää organizes amazing safaris for all guests, for example

Searching for Northern Lights

a guided trip with snow shoes to nearby fells in the late evening to see the fantastic Aurora Borealis.

On a Reindeer Trek

A reindeer caravan has been harnessed for you in the reindeer yard ready for your journey into the silent wilderness. Guided by an original Sámi reindeer herder, you will drive your own reindeer along the journey. The reindeer will take you across the enchanting snowy white scenery. The frost glistens like diamonds on the shoulders of the pine trees. You sit warmly and comfortably on reindeer skins in a sleigh. Reindeer bells gently ring as their hooves crunch through the snow. When the reindeer caravan returns to the yard, the experience of a warm “kota” awaits you. Enjoy some hot drink while a reindeer herder gladly tells you stories of his life in the wilds of Lapland. Transfer to and from reindeer farm.

Searching for Northern Lights on a Reindeer Trek

Reindeer caravan will take you in to the woods. Moon and stars will guide your way and the silence of wilderness will around you. Hot drinks and stories about reindeer in the kota after the sleigh ride. Transfer to and from reindeer farm.

And More

For more information about the safaris, including prices, see the brochure here or visit the official website.

Picking the right clothes for the Lapp winter

Basically, the most important thing in Lapp winter is to wear clothes in layers.

Here I’ll describe what I often wear, when in Lapland, whether snowboarding, skiing, or hiking (in winter).

Inner layer

For me, clothing always starts from the innermost layer. For me, it is the most important, that this particular layer insulates well and does not get/feel wet. Merino wool underwear is my choice - nowadays I typically wear 100% merino wool from smartwool

If it is cold, say more than -10, I typically wear strechmesh underpants that insulate too rather well. On top of that, I might have some extra middle-wear, but only if I am not going to do any physical exercise. Or if it really cold. With this setup (of inner layers), I’ve been skiing in -25C easily.

Similarly I wear on my body - merino wool t-shirt, another layer of merino wool, with some mesh shirts. Typically I wear, like this. 2-3 layers of very thin merino wool / mesh shirts. On very cold days, I might add one more merino wool shirt.

Middle layer

Middle layer is something I typically wear only when I’m not doing anything physical. Or, when in Codefreeze, probably all the time. Especially in the Stars and the Moon night trek - it’s not going to be much of an exericse - cold it might be.

In middle layer I wear, for the biggest suprise, either more merino wool, or something totally different, either something made of PolarTec or Fleece.

Outer layer

For outer layer, it’s enough that it is wind resistant. And maybe cozy enough to wear. I typically don’t wear anything super expensive GoreTex jackets/trousers. In winter, I myself have both soft shell jacket, like and an anorak, like. I use an anorak when skiing, and a soft shell jacket when snowboarding. Why - I don’t really know.

For trousers, something comfy and windproof, like these Fjällraven trousers.

Anyway, the most important thing is, that it should be wind resistant. At least if planning to do any physical exercise above the tree level.

Other garments

Others then?

Hats? Merino wool Buff - don’t hesitate. But two of those. Or three. That way, you can have a very warm hat (2 Buffs) and one very warm neckwarmer. Or bring normal hat, under which you can have a Buff hat.

I have 2 merino wool Buffs always with me. And some other hats, some are windproof, most are not.

Gloves? I have, surprise again, merino wool inner gloves with warm outer gloves. Actually I have so many different kinds of gloves I can’t even count. When doing anything physical, I wear very thinly gloves. Other times I wear the most warm I find. For you - bring at least some gloves.

Socks? Could you guess? I wear only merino wool socks. Nothing else. Matters.

Boots? There is 60-100cm snow on the ground. I highly encourage to wear boots which cover your ankles. Especially important if you plan to take a snowshoe trek. You can rent proper boots from the ski rental shop in the basement of the main building.

Few more words

That’s what I wear. Mostly merino wool. Except of some inner layer mesh clothes and the outermost layer, which has to be windproof. Easy, isn’t it. I wear using the same principles year around, if hiking / cycling in non-summer temperatures -> I wear merino wool 1-N layers with wind proof (or GoreTex) outer layer. Easy.

For Codefreeze, for you - what to bring. No need to buy everything. If you want something - think about buying something made from 100% merino wool - that I think would provide the most value and that could be used later. Buff. again - my favorite garment of all: merino wool Buff. It made of awesomeness, in it’s pure form. It has to be.

Note: You need only maximum two pieces of each Merino item; they are after all quite expensive. Merino wool does not start to smell quickly like cotton. And you can put it outside over night which will kill bacteria.

Anyway, I’ll bring most of my gear. I’ll be around from Sunday evening until Thursday (early) morning. I will be helping with the outer layer - so that no-one actually needs to freeze.

And, if you’be read this far - please bring swimming suit. I know, we are in Finland and in Finland we go to sauna naked. That’s true, except in (most) public saunas, where there can be anyone. And, swimming suit is nice when dipping into the rather refreshing water nearby the sauna.

#proTip: To acclimatize ourselves (I do this too, and I’ve experienced the benefits already) - when we’re taking a shower, let’s turn the knob to the coldest and enjoy a really refreshing cold shower. For a few seconds (at start) and then few tens of seconds. Doing that, and freezing cold temperatures in Lapland don’t feel that cold anymore.

Attending Codefreeze with Children

Are children welcome at Codefreeze?

In short, yes. We’d love for you to bring your kids.

Will there be other kids?

Usually yes. It helps to connect with other parents so you can arrange sessions for children that need preparation.

What kinds of things might my children enjoy at Codefreeze?

The snow (it might be clean enough to eat). Slayrides, going downhill on the slope with the totem pole - it gives you a sense of accomplishment. Making friends with the other kids. The quiet outside. The sauna (on lower temperatures or with a little bathtub). Some children have even enjoyed the dip - maybe you can make some badges for their accomplishments?

What kinds of things might be frustrating for my kids?

Adults will mainly speak English to each other which they might not understand. The marketplace takes quite long so it is good to find something to do nearby. Children usually need structure and Codefreeze can become quite loud and unorganised - you might need someone to tell them what to focus on. Some sessions might not be suitable for kids.

Is there someone who can provide childcare for my kids?

Not officially, but you can connect with other parents to maybe arrange something.

Do all children speak [my language]? What age are they?

Children of all kind of native languages will join and they don’t all speak English. Young kids sometimes become friends even if they can’t verbally communicate. They have been of varying ages from 2 years upwards.

I can’t bring my kids because of the school holiday - can you move the dates?

Sorry, we can’t move the dates at the moment but you can look into participating part of the time. In some countries/schools it might be possible to arrange an exception for a few days and have children do homework during the time. Children can learn a lot about Sami culture and possibly bring that back into their schools. Depending on the weather you could do some science experiments like throwing boiling water into the air and have it frozen or making popsicles in the snow. Other ideas: blow frozen soap bubbles, popcorn on the fire and watching a movie.

Is the food child compatible?

The food provided by the venue is very greasy and you might struggle if you have food intolerances. Lunch is usually quite salty soup & salad. Children usually enjoy the dinner. It’s possible to self cater in the accommodations - there is a small shop in a town nearby or you could bring your own ingredients. The tap water is very good but you need a bottle or thermos to bring water on hikes.

What should I know about accommodation?

Cabins might be 15m walk away but could be easier with sleds. However the number of sleds is currently limited, you might ask about increasing them with reception in advance. Wilderness cabins only have one room with bunk beds which might not work for you. There are some bigger cabins (for 10 people) that are more expensive (pohiamm ukku?) which have extra rooms that can provide more privacy if your children are fuzzy sleepers. These are not part of the Codefreeze packages

Which of the activities are good for kids?

What should I pack in addition to the official packing list?

Where can I get more information regarding attending Codefreeze with children?

If you have further questions, ask them in the #kids channel on Matrix or ask Aki.

Code of Conduct

All attendees of Codefreeze are required to agree with the following Code of Conduct.

Codefreeze isn’t an officially organised event. For enforcement of this Code of Conduct, we only have official authority of the private accommodation we are using for sessions and the activities we organise. With everything else, we will try to work on enforcement with the Suomen Latu staff and local authorities. This is still a public space used by non-participants as well, please don’t assume that everyone has read or will follow this Code of Conduct. This Code of Conduct applies to the event itself, and to all digital spaces that are related to the event, such as GitHub, Slack, Matrix, Trello, and Wekan.

Inclusiveness

A goal of Codefreeze is to be inclusive and welcoming to attendees with the most varied and diverse backgrounds possible. Please read our full Code of Conduct before booking, discussing online and before coming to Codefreeze. But please don’t feel intimidated by it—these are simple rules, and they will make life better for everyone at Codefreeze.

Why we have a Code of Conduct

We are dedicated to create an event where everybody can learn, teach, share, network and have a good time. This can only work if we are inclusive to the largest number of contributors, and if we create an environment, where everybody feels safe and welcome. Yes, we value discussion and disagreement. And discussion can become heated. But there have to be rules, and there has to be a red line. In this Code of Conduct, we lay out those rules and red lines.

Safe Environment

We are committed to providing a friendly, safe and welcoming environment for all, regardless of gender, sexual orientation, age, field of expertise, ability, ethnicity, socioeconomic status, and religion (or lack thereof). And so we invite all those who participate in Codefreeze, and the community surrounding the event, to help us create safe and positive experiences for everyone. With your help, this event can be a great experience for everyone! Treat everyone professionally. Everybody at the conference is a professional in their field. Treat all attendees as equals. Ask before you teach. Do not explain things without being asked. Be welcoming, friendly, and patient. Give people the benefit of the doubt. Ask questions before jumping to conclusions. Be respectful. Not all of us will agree with each other all the time, but disagreement is no excuse for poor behaviour and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. Be aware of the effect your words may have on others. We are a community of professionals, and we conduct ourselves professionally. Be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren’t acceptable. Be careful with jokes. We do not tolerate any Code of Conduct violations, even if “it was just a joke”. Admit when you do not know something. Encourage others to admit when they do not know something—and never joke about it. We are all here to learn. There might be people taking photographs. If you don’t want to be photographed let them know. If you want to publish a photo, ask the people in the photograph first. If you’re involved in outdoor activities, look after each other and be mindful that not everyone has the same ability. Please respect nature and the instructions from the official guides.

Code of Conduct Violations

If you think someone has violated our Code of Conduct—even if you were not directly involved, like you just overheard a conversation—please:

But please give people the benefit of doubt. If there is even a slight chance that this was a misunderstanding (e.g. the person did not speak in their native language, and did not find the right words), try to sort it out in a friendly, constructive way.

When we learn about a Code of Conduct violations, volunteers will hear both sides, and then take action we deem appropriate, such as:

Unacceptable Behaviour

Unacceptable behaviour includes, but is not limited to:

To clarify, although this doesn’t take away from the other rules, it is ok to be naked in private saunas and changing rooms, but not mandatory. If you are unsure about what is appropriate or if you’re uncomfortable about this, please talk to a volunteer listed below.

Need Help?

If you need help, have any further questions or have any other concerns, please contact a volunteer immediately.
