Iso-Palonen – Maariansärkät Nature Reserve

The Iso-Palonen - Maariansärkät Nature Reserve (4,031 ha), located in the eastern part of Kuhmo, is a tapestry of small lakes, numerous ponds, pine heaths and eskers.

Snowy coniferous forest.

The esker formation crossing the reserve has been an important area for the migration of the wild forest reindeer. Here, amidst the eskers, they have found a sheltered feeding and breeding ground. In this same environment, hikers can also find a place where they can break loose from their everyday routines, let their minds rest and enjoy the offerings of nature.

Nature and Sights

The best attractions in Iso-Palonen - Maariansärkät are the esker formations and the small and large water bodies intersecting them. Also, worth your attention are the traces left by humans during various epochs. The structure of the forests shows that humans have used them for a long time. You can see the bases of tar-burning pits and traces of human settlement dating from the Stone Age.

The Iso-Palonen - Maariansärkät Nature Reserve includes some of the headwater lakes of the so-called Kalliojoki Route, strips of land connecting them, and esker formations. Nature in the area is stark. The landscape is characterised by an alternation of light-filled pine forests, mires and bodies of water.

Most of the forests in Iso-Palonen are rather old, pine-dominated dry heaths. Almost all forests are managed and even-aged. Forest management measures were widely carried out as late as the end of the 1980s, just before the nature reserve was established.

The mires, of which there are not many, are mostly pine bogs and open mires.

The most notable bodies of water are Lakes Iso-Palonen and Veräinen as well as the Viiksimonjoki River, which together make up the popular Kalliojoki Canoeing Route. There are also many kettle hole ponds, “suppa”, formed by retreating glaciers.

Historic and prehistoric dwellings were usually located on lakeshores. There are so-called Lappish graves along the hiking trails, i.e., the remains of old wild forest reindeer hunting pits. Traditionally the hunting of wild forest reindeer has been an important additional livelihood in remote areas.

The area is home to mammals and birds, characteristic of the Kainuu Region. Your chances of seeing wild forest reindeer in the Iso-Palonen - Maariansärkät Nature Reserve are rather good. If you move quietly, you may see a female wild forest reindeer bring its fawn to a mire to feed, or male reindeer attack each other in autumn during the mating season. Wild forest reindeer are encountered in the area throughout the year.

  • Most of the time, the Kalliojoki Route traverses uninhabited areas. Habitation is found only in the small village of Kauronkylä and the region of Kattilakoski.
  • Cleared passages along the Kalliojoki Route were restored during the years 1978 - 1979 by placing rocks in the rapids. However, a two-to-three metre passage has been left open for boating.
