The trail goes through varying landscape, including herb-rich forests and grove-like moist forests. The duckboard bridge with handrails, which crosses Linnansaarenlampi Pond, can be slippery when it rains. Sturdy shoes are needed on the trails of Linnansaari. 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.
