Always use extreme caution when handling fire. The one who lights a fire is always responsible for its safe use. Please note, that making fire at these campfire sites can be banned locally.

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.

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.


  • For longer treks we recommend that you take a large bottle of water as lake and flowing water may be scare in dry seasons or it could get soiled by animals or bacteria. Water taken from lakes or rivers should be boiled before drinking it.

  • When in the middle of a thunder storm it is best to not climb to the tops of hill as there is a danger of getting hit by lighting in high open places.
  • When a lot of snow has fallen, the trees at tops of the Ukko-Koli and Mäkrävaara hills may cause dangerous situations when their branches break under the strain of the snow.
