Next to the ridge, the Finnish Forest Research Institute has been growing trees here since the 1920s — a working laboratory rather than a manicured park. Hundreds of species are planted in stands and lines, with labels giving the Latin name and origin. You can see Siberian larch, North American Douglas fir, Japanese spruce, and a famous "clone collection" of Scots pine that maps the genetic variation across Finland.
It is not a manicured English garden. Paths are gravel, signs are functional, and the trees are planted to be measured, not to be admired. Botanists and forestry students love it; for casual visitors it is a calm, slightly nerdy walk in the woods that pairs well with Lusto next door.
