Mobile Phone Coverage

  • Although Finland has a broad network for mobile phones, there are some areas in the Sompio Strict Nature Reserve without signal. There may also be some smaller spots where there is interference. If this happens try to climb to a higher place or go into an open area. It may be worth removing the SIM card from your phone and then trying again to make emergency call. Different phones also differ in their coverage.
  • We recommend that you keep your mobile phone warm at all times and take along food and drink. Certain phone models do not work when the temperature falls below zero. You should therefore let someone know your planned route. To keep your mobile phone charged, bring along a spare power source, a spare battery or an old phone with a working battery.

A Considerate Hiker

You won't leave any traces of your visit to the Sompio Strict Nature Reserve, will you? You will find tips for environmentally sound hiking on the Hiking in Finland webpages.


  • Take the different seasons into account when considering equipment and provisions.
  • The most important pieces of equipment on a hike are a sheath knife, matches, a map and a compass. You should take them with you even on the shortest day trips in addition to packed meals and drinks. More information on equipment and hiking can be found in hiking books and on the Hiking in Finland webpages.
  • Make sure you pack a first-aid kit.
  • Take food preparation equipment and your personal cutlery with you.
  • There is not a stove at the Pyhä-Nattanen Day Trip Hut.
  • There is firewood in the woodshed.
  • There is a saw and an axe at the lean-to shelters, the Lapp 'kota' huts and at the Pyhä-Nattanen Hut. However, it is advisable particularly for winter hikers to take their own saw and axe with them. There may be spare saw blades by the wall of the woodshed.
  • There is a water bucket and a scoop, a waste bucket, a guestbook and a fire alarm at the Pyhä-Nattanen Hut.
  • Take a battery (V9) with you, as moisture and the cold may weaken battery function.
  • The hut's folder contains instructions for using the equipment and for the correct behaviour at the hut.

Safety Tips

  • You can practise hiking on day trips. It is recommended that a person who has good wilderness skills participates on longer hikes.
  • Remember to inform your friends, close relatives, your place of accommodation or the Urho Kekkonen National Park's customer service points about yourself, your schedule and your route plans. Also inform them, as far as possible, of any changes to your route and schedule. Write your name in the guestbooks at huts and lean-to shelters, as that facilitates the helpers' work in an emergency. The area's rescue service has been statutorily organised and it can be reached via the Emergency Response Centre (ERC). Remember to inform others about your arrival at the destination in order to avoid any unnecessary search alarms.´Remember that the telephone number you must first use in an emergency is 112.
  • If you face an emergency on your hike, e.g. get lost, get injured or observe wildfire, call 112 and report an emergency. More information on how to act in an emergency.
  • Make sure you pack a first-aid kit.
  • Hiking in winter is demanding. In midwinter the weather and light conditions are difficult, as it may be –40 C and there are only a few hours of daylight during the polar night. Windy conditions significantly increase the bitterness of the cold weather.
  • Avoid hiking alone. In an emergency a fellow hiker is indispendable.
  • Late winter is a popular time for hiking, but you must have proper gear then, too. Do not go to the Sompio Strict Nature Reserve with the usual cross-country skis!
