Kurjenrahka National Park: Introduction

Sphagnum moss keeps growing on top of its own dead layers, the peat thickens to several metres, and eventually the whole dome stands high enough above the surrounding land that nothing reaches it except rain. Rain carries almost no nutrients. That is the trick: the bog engineers itself into poverty, and then a very specific set of species moves into the poverty and thrives. Kurjenrahka, the bog at the centre of this national park thirty-five kilometres north of Turku, is named for the birds that patrol it. Kurki is a crane, and rahka is the bog itself.

As the moss creates its own conditions, wetter and drier patches feed back on each other, and the surface differentiates into hummocks and hollows and pools, each supporting a different set of plants. Much of Kurjenrah...

The place that gathers the human history is a boundary marker called Kuhank...

In 1958 a decision was taken to leave Pukkipalo as old-growth forest, and it survives as the most impressive ancient woodland in the province, thick with big trees and with the standing and fallen deadwood that a working forest n...

Kurjenrahka National Park: Duckboards, Towers and Cloudberries

Mon, 17 Aug 2026 00:00:00 GMT

Photo credit LPfi, CC BY-SA 4.0. Walking a bog means walking on planks. Duckboards carry the trails across the wet ground, and in spring, when the snow goes, some of them disappear under standing water. The Kuhankuono network and the Suokulla route together offer around 300 kilometres of marked trail, ranging fr...

Kurjenrahka National Park: The Seasons Nobody Books

Mon, 17 Aug 2026 00:00:00 GMT

Photo credit Urjanhai, CC BY-SA 3.0. Restricted zones close parts of the park to off-trail travel while the birds are nesting, from mid-April to mid-July, and Lammenrahka from mid-January. This inconveniences almost nobody, since crossing an open bog in summer is exhausting work at the best of times. Winter inverts ...
