Activities in Pyhä-Häkki National Park

The best preserved old-growth forests in Southern Finland offer plenty to see. Hike to admire 400 year-old ancient pine trees, traces of forest fires from centuries ago or the historical crown tenant farm croft at Poika-aho.

Sights and scenery

Discover the wonders of ancient forests! In the magnificent pine forests of Mastomäki, the trees are 250 years old on average. The park's most famous ancient pine tree, the Big Old Tree, which is now a snag, began growing in 1518. The giant's diameter is 288 cm. The new Big Tree, chosen in 2006, dates back to 1641 and is alive and well along the Mastomäki circular trail (3.2 km). The Big Old Tree still stands tall around 200 metres along the Kotajärvi circular trail.

History is brought alive at the Poika-aho Crown Tenant Farm, its courtyard and meadows. The farm in the western part of the park was established in 1854. The main house is a rental hut used by sheep herders in the summer.


Hiking is the best way to reach the sights in the park and enjoy the wild. There are approximately 30 km of marked trails in the Pyhä-Häkki National Park. Choose the one you prefer from among the four circular trails (1.4–17 km), pack a picnic in your rucksack and embark on an adventure.
