Kalevalsky National Park, National park in Karelia, Russia.

Kalevalsky National Park covers 74,400 hectares of old-growth boreal pine forest on the Russian-Finnish border, about 30 km north of Kostomuksha. The park holds 400 lakes and 250 streams; 85% of its area is pine-dominated forest, 9% marsh and 6% water. The western part is flat and waterlogged, while the east rises into hills and ridges between 105 and 278 metres.

Kalevalsky National Park was created on 3 July 2007 across 74,400 hectares of the Kostomuksha urban district, with its western boundary on the Russian-Finnish border. On 16 March 2015 it became part of the Kostomuksha State Nature Reserve. Its founding aim was to protect one of Europe's last large tracts of old-growth pine forest.

The park takes its name from the Kalevala, the Finnish and Karelian epic compiled by Elias Lönnrot from oral poetry collected in this part of Karelia. The traditional inhabitants of the area were Sami and Karelians, and the park's tasks include restoring sites tied to traditional taiga land use. Visitors pass the villages of Voknavolok and Kalevala, from which local residents are drawn into tourism work.

The park features marked trails and observation points that allow visitors to explore the forest and lakes on foot. Bring appropriate gear for the northern climate, as conditions are cold with long winters and the terrain can be boggy underfoot.

The forest floor here consists of thick peat layers that have accumulated over millennia, creating ecology unlike southern forests. These bog landscapes have become rare in Europe and attract specialized plants and animals found nowhere else.
