Torronsuo National Park is situated in the Southern Finland.
Even before its declaration as a national park in 1990, the near-natural state swamp area was a protected area.
The park area is a typical ombrotrophic raised bog – a thick turf layer with its middle part raising above its edges.
The turf layer is one of the thickest measured among Finnish bogs, locally extending to 12 metres (39 ft).
