On the Karnaistenkorpi nature trail, you can find the atmosphere of wilderness close to the metropolitan region. If you have sharp eyes, you may also spot the Threetoed Woodpecker and the Eurasian Pygmy Owl that nest in the area. The trail offers a fairytale setting for both quiet walks, exciting adventures for the children, and orienteers training for competitions. A curious feature of the area is that you will be trekking over a motorway without even noticing.

Trail description

The Karnaistenkorpi nature trail is located next to the Lohja Ridge, and is a part of a forested area of 200 hectares owned by the City of Lohja. The trail travels through an old spruce forest. The terrain is varying, and you can see barren rock, bog depressions and quiet forest ponds along the trail. You can stop for a rest along the way at two different lean-tos to roast sausages. The rest areas also have firewood, toilets and water for extinguishing fires. There are several information boards next to the nature trail describing the fauna and flora of the area.

Good to know

There are no waste bins, so you must remove all waste from the area. There are no drinking water stations in the area. In dry weather, the trail is also suitable for training shoes. When it rains, the duckboards become slippery. The trail is also kept passable on foot during the winter. The signage on the trail is in Finnish only.

Difficulty level

The trail winds through the forest, partially over duckboards that are slippery when it rains. The trail has plenty of roots and stones that make walking more difficult. There are occasional steep rises and descents through challenging terrain. The trail requires good physical condition and agility.
