Preparations

Mobile Phone Coverage

  • Although Finland has a broad network for mobile phones, there are some areas in the park 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.

Equipment and Safety

  • Visitors need to carry their own food and drinks. The water in the well at Heretty has been tested and found to be good for drinking. 
  • Please note that there is no toilet paper in the toilets.
  • Suitable footwear depends on the weather. When it is dry, trainers will be fine, although the trails are rocky at some places, so study outdoor boots may be more practical.

Peak Seasons

  • The most popular times to visit the National Park are the weekends in the spring and autumn, and the summer months of June and July.

112 Suomi - mobile application

When an emergency call is being made through the 112 Suomi - mobile application (112.fi) the dispatcher will automatically receive the callers position. 

It is recommended to keep the mobile phone warm and to bring extra food and water with you. There are many excursion locations with no mobile coverage and some mobile phones does not work in sub-zero temperatures, that is why it is always a good idea to let someone know about your itinerary and timetable.
