The Helvetistä Itään Nature Trail from Kankimäki to Helvetinkolu, 4 km. The old trail, which has badly eroded in places, has now been replaced by a new circle trail that is taken anticlockwise. After branching off from the forest road coming from Kankimäki, the northern part of the trail winds through the brook-side spruce forest, light-filled pine forests and past mire depressions towards the rugged gorge. The southern part of the trail takes you across wet treeless mires, stunted pine bogs, brook-side forests and finally to the forest road that leads to Kankimäki. Along the trail you can admire a waterfall recovering from the rainy weather, or you can sit down at a picnic table and take a rest break in the beautiful mire landscape, where you can see signs of peat moss digging. Use of the old trail has been discontinued. There are information boards along the new trail on the natural features and cultural history of the area.

In winter it is possible to walk in the National Park with or without snow shoes, or to go cross-country skiing. In the park area the trunk roads are ploughed. Walking trails are not maintained in the winter, but the trail from Kankimäki to Helvetinkolu Gorge is often quite clear around the year. South of the National Park, depending on snow conditions, runs Kuru-Ruovesi skiing trail which is maintained by the municipality of Ruovesi (www.ruovesi.fi) and the town of Ylöjärvi (www.ylojarvi.fi).
