Linnaistensuo mire, located only seven kilometres from the centre of Lahti, is a nationally valuable raised bog. The tranquil mire landscape can be admired from the duckboard trail crossing it. Linnaistensuo mire is part of the national mire conservation programme and one of the sites of Salpausselkä UNESCO Global Geopark.
On Linnaistensuo mire, surrounded by mixed forests, moist hollows alternate with drier hummocks. The flora of mire is typical for raised bogs and the representativeness of the mire makes it valuable protected site.
The nature trail, about 1,5 kilometres long, runs mostly on duckboard trail. The information boards along the way tell about the mire ecosystem. Linnaistensuo mire can be reached along Korvenrannantie or Linnaistentie and Ilolantie roads. The paths leading to the duckboard trail are marked on the trees with yellow paint.
