Mobile Phone Coverage
Although Finland has a broad network for mobile phones, there are some areas in the park where cliffs or forest block signals. 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.
For their own comfort visitors should wear water-proof calf-high shoes during spring and early summer, as their pants are likely to get soaked otherwise. During dry weather sneakers are suitable foot wear for the Patvinsuo terrain. Mires and wetlands have duckboards.
During summer mosquitoes and sand flies thrive in the park's mires. The wind sometimes clears the air of them for a short time. ‘Elk flies' (Lipoptena cervi) buzz around visitors during autumn in the middle of forests.
Remember to pack food with you as the closest shop is 33 km away in Hatunkylä Village.
