When the snow conditions are good, there can be up to 45 km of classic cross country skiing trails in Torronsuo National Park. The Torro-society is responsible for trail maintenance from 1 January–30 March, and maintenance work is mainly done on weekends. Routes to choose from include Kiljamo-Kallio (5 km), Katavasaari-Riihivalkama-Kallio (13 km) or Kiljamo-Katavasaari-Kiljamo (15 km), a trail in even terrain featuring a campfire site.

Starting points for skiing trips include the national park's parking area at Kiljamo or the Hakala estate by Somerontie road. Maps of ski trails are available online at the Torro village website (in Finnish). You can also enjoy winter in Torronsuo by creating your own ski trail in the terrain.


There are several marked trails across the even Torronsuo terrain (1.5–10 km). A 1.5 km trail, partly covered with duckboards, runs round the island of Kiljamo. This circular trail introduces visitors to the open central parts of the Torronsuo bog, the pine mire and the diverse natural environment of the forested mire islands.

The trail (around 3 km) starting by Kiljamo campfire site runs across the Torronsuo bog to the old Härksaari quarry. Using a map, you can continue via the Torro village (10 km). The Torronsuo trails form part of the Ilvesreitti trail network in the Häme lake uplands (, in Finnish).


Pack your binoculars and a bird atlas in your rucksack and come to Torronsuo to watch birds migrating in the spring or autumn. Large flocks of cranes gather in the vicinity of the national park to feed, and arrive at the mire in the evening to spend the night. Many other species rest in Torronsuo while migrating. The best place to observe birdlife is the Kiljamo nature tower.
