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.
At the sea it is always important to be prepared for quickly changing weather conditions. Especially important is to make sure that the boat is in good condition.
Nautical charts are also necessary, the archipelago area is covered in the series D.
When walking on the islands, it is good to remember that the rocks are slippery when wet, and so are moss and algae.
Ticks live in damp grass, and some of them carry viruses and bacteria which cause diseases. It is especially important to cover your legs, which is easily done by wearing your socks on top of your trouser legs. Tick pliers and tick check done every night are also essential.
Snakes are common in the archipelago, so it is advisable to watch out when walking.
Make sure you pack a first-aid kit.
If you face an emergency on your hike, e.g. get lost, get injured or observe wildfire, call 112 and report an emergency. Maritime Rescue Centre's calling number is 0294 1000. More information on how to act in an emergency.
