Polar regions and tundra: overview and expedition preparation
The Arctic, Antarctic and tundra combine extreme cold, strong wind, great remoteness and unusual light. In summer the tundra turns into a wet, mosquito-rich surface over permafrost. Anyone who wants to go there first gains winter experience in nearer regions, takes training and travels with experienced guides or an organised expedition.
- Months to years of preparation and training

Explained simply
The Arctic in the north and the Antarctic in the south are among the coldest places on Earth. Between them and around their edges lies the tundra: wide, treeless land whose ground stays frozen deep down all year round. It can be very cold and very windy there, and the nearest place with people is often incredibly far away.
In the cold everything takes longer. Opening a zip with thick gloves is like tying your shoes wearing oven mitts. Every small mistake – a lost glove, a wet sock – can quickly become a big problem there, because help takes hours or days.
The most important point: nobody simply travels to the polar regions as a beginner. You first gather a lot of winter experience in nearer places, take courses and travel with experienced guides or an organised expedition.
How it works
In polar regions several forces work together. The air is very cold, and wind constantly strips away the warm layer of air around the body – which multiplies heat loss. Exposed skin on the nose, cheeks, fingers and toes can freeze very quickly in extreme cold and wind. At the same time every task takes more time and more warmth, because you do it with gloves and thick clothing.
Remoteness is the second big factor. There is usually no mobile coverage, rescue can take hours to days, and bad weather can keep planes and helicopters on the ground. A sprained ankle that would be annoying at home can become a serious situation there.
In summer the tundra shows a different face. Only the top layer of soil thaws above the permafrost, the permanently frozen ground. The meltwater cannot drain away, and the land becomes a wet, boggy carpet with many mosquitoes. Rivers often have no bridges, and depending on the latitude the sun does not set for weeks.
Building experience step by step
Polar trips are not an entry point but a goal at the end of a long path. A step-by-step build-up makes sense: first winter trips with overnight stays in familiar areas, then multi-day trips in cold regions, then a guided polar trip. At every step you learn how your body and your gear react to the cold.
Courses in winter camping, cold protection, navigation in poor visibility and emergency communication are part of it. Many skills that are taken for granted in summer have to be practised anew in the cold: operating a stove with gloves on, pitching a tent in a storm, staying dry in your sleeping bag at night.
Test your gear as a system in real cold before you leave: clothing, sleeping bag, sleeping pad, stove, gloves. Discovering that a buckle cannot be opened with gloves on should happen at home, not on the ice.
Safety: what to watch out for
Frostbite often begins unnoticed, because the affected area goes numb. So check each other's faces in the group, especially nose and cheeks, and speak up immediately if skin turns whitish or waxy. If you suspect it, protect the area and get help. The Wilderness Medical Society has published guidelines on frostbite and hypothermia that describe how limited treatment in the field is – prevention is therefore everything.
Stoves produce carbon monoxide, a gas you can neither see nor smell. In a closed tent or a snow cave it can become dangerous. Ensuring good ventilation is one of the most important rules in the cold, even if you would rather keep the warmth inside.
Satellite-based emergency communication and a filed trip plan are basic requirements: route, schedule, means of communication and fixed check-in times with a reliable contact person. Polar bears live in some polar regions; special local rules and protective measures apply there, which you find out from the authorities and operators.
Light, darkness and technology
During the polar night it stays dark for weeks depending on the latitude. That requires reliable light sources, spare batteries and a firm daily structure so that the body keeps a rhythm. In summer it is the other way round: the midnight sun disturbs sleep, and an eye mask can help a lot.
Batteries lose a lot of their power in the cold. So carry spare batteries and phones on your body, for example in an inside pocket, and take them into your sleeping bag at night. Electronics can still fail – a map and compass always belong in the kit.
Good to know
Many polar areas have permit, insurance or equipment requirements, and the Antarctic is subject to particularly strict international environmental protection rules. Clarify such questions early with authorities and operators – this text gives no legal information.
Polar expeditions are a specialist field with their own training. This text puts the risks into context but replaces neither courses nor experienced guiding. Those who take their time and build experience step by step can experience these special landscapes more safely.

Materials
Sleeping bag
Rated for the expected lowest temperatures
Do not store compressed long-term; do not pack away damp.
Sleeping pad
Stove
Never operate inside a tent, shelter or enclosed room – carbon monoxide and fire risk.
Suitable for
- Planning guided polar trips
- Understanding the risks before an expedition
Not suitable for
- Independent first expeditions without experience
- A substitute for expedition training
Prerequisites
- Several winter trips with overnight stays in nearer regions
- Training in basic cold-injury awareness and emergency communication
- Experienced guides or an expedition organiser
Safety
- Polar bears live in some polar regions. Special local rules and protective measures apply there – ask the authorities and operators.
How it works
Polar cold is above all a matter of time and wind: every task takes longer with gloves, every mistake costs more heat, and wind multiplies heat loss. Remoteness turns small problems into big ones because help is far away. In summer only the top layer of soil above the permafrost thaws – water cannot drain away and the tundra becomes boggy.
Advantages
- Little precipitation in many polar deserts
- Frozen surfaces can be easy to travel on in winter
Disadvantages
- Extreme cold and wind
- Great distance to help
- High costs and requirements
