The Urho Kekkonen National Park, which is the second largest of its kind in Finland, was established in 1983. The northern part of the park is tundra featuring several fells culminating at over 500 metres. The park is home to a very dense network of day cabins, wilderness refuges and campsites.
The signposted routes and nature trails within the Urho Kekkonen National Park can be reached via Saariselkä, Fell Centre Kiilopää, Lake Sompiojärvi as well as the parking areas at Kemihaara and Haukiniva (Nuorttijoki). There are trails to suit all schedules and fitness levels from a 1-kilometre hike to treks lasting several days. The most recognisable sites within the park are Lake Luirojärvi and the Sokosti Fell.
