It is important that you get as much information as possible about your hiking destination in advance and prepare for your trip thoroughly. Knowing your route and sticking to it and knowing what the weather and warnings in effect (en.ilmatieteenlaitos.fi) has in store, will help make your trip a success.

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. More information on how to act in an emergency.
Mobile telephones work quite well in Päijänne National Park, except in some areas in the park where cliffs or forest block signals. Download the 112 Finland application (112.fi) to your phone.
Dress for hiking in colorful clothes and according to the weather. Some of the islands consist of rocks, but on most islands a visitor can walk in a dry forest. When choosing footwear, it is good to remember that there are also sandy shores.
It is good to bring a map if you go to the islands in the national park. The brochure map of the park may also be enough, especially for smaller islands and islands with signage. Most of the islands are small and the biggest one, Kelvenne, is easy to explore as it is long and narrow.
The water areas of Päijänne are not part of the national park. Please pay particular attention to safety as you move along the waters. It is good to bring a nautical chart or the like.
The wind is sometimes strong on the lake but in many of the natural harbours, especially on Kelvenne Island, it is possible to find a sheltered side.
Because the area of the lake is large, the weather conditions can change suddenly. Sometimes a strong northern wind blows from Tehinselkä, the largest open water area of the lake, and makes big waves on Virmailanselkä open water area east of Kelvenne. From Harmoistenlahti Bay, south of Virmaila, a strong wind sometimes blows through Kellosalmi strait to the northern parts of Padasjoenselkä open water area.
There are no cafés, shops or tap water available in the National Park. It makes sense to pack food and drinking water.
Please note that there is no paper in the toilets.
