Activities in Puurijärvi and Isosuo National Park

The Puurijärvi and Isosuo National Park provides a sanctuary for wild birds in the precious cultural landscape of the Satakunta region in southwestern Finland. Come for a day trip spent hiking and enjoying the wilderness.

Parts of the Puurijärvi and Isosuo National Park are closed off to the public during certain times of the year. Please respect the signs!


The bird sanctuary gives you time to slow down, stop, look and listen. Climb up to the roofed birdwatching tower on Kärjenkallio, one of the largest in the Nordic countries, with room for around 50 people. The birdwatching towers on the southern side of Lake Puurijärvi, in Mutilahti and on the northern side, in Ahvenus, are approximately 4 metres high. A nature watching tower is located on Isosuo Mire.

The most common bird species in the park include the meadow pipit (Anthus pratensis) and yellow wagtail (Motacilla flava). Many waders nest in the mires, including the golden plover (Pluvialis apricaria) and wood sandpiper (Tringa glareola). Isosuo mire is the most valuable area in the park in terms of its birdlife.

Nature trails

The nature trail (2 km) on the northern side of Isosuo Mire introduces visitors to the mysteries of the marshland. You can watch the scenery and observe birdlife in the 4 m-high nature tower along the trail. A trail to the turf shelter (100 m) branch off from the main trail.
