Circular trail, 7 km, is the most popular hiking trail in the park. The trail is in quite difficult terrain, and it is marked with orange circles. The trail goes through varying landscape, including herb-rich forests and grove-like moist forests.

The trail goes to Linnavuori Rock scenic lookout place, where the view over the lake landscape of Haukivesi is worth seeing. Walking this trail takes 3 - 4 hours.
