The Finnish Natural Heritage Foundation acquired the Kyöpelinvuori Forest in the autumn of 2004. There are all kinds of surroundings in this area of 17 hectares: a brook with its shores, the top and the slopes of the Kyöpelinvuori Hill as well as some small cliffs, heaths, and backwoods. The landscape is dominated by conifers of different ages, but there are a considerable number of deciduous trees growing there as well, especially birches and aspens.

One walking through the forest will be amazed by the diversity. From the lush shores of the Vaaherpuro pond, one can quickly move to a completely different environment, to the top of the Kyöpelinvuori Hill, to see the old pine trees covered with beard moss and lichen. The name Kyöpelinvuori (‘Ghost Mountain') indicates that people were intrigued by the exceptional shape of the hill in the old days. When one comes down from the hill, one can, for instance, hike to the nearby wilderness, where spruces, birches, and aspens covered with white lichen rise from the ground, which is covered by an unbroken carpet of peat moss.

The several large anthills in the area tell for their part about the continuous state of nature.

The birds nesting in the forest include, for instance, goshawks and three-toed woodpeckers.

In the summer of 2006, the Finnish Natural Heritage Foundation helped the Pro Luontokuva association to acquire a forest of 1,3 hectares on the side of the Kyöpelinvuori conservation area. The forest was placed under protection, so these two conservation areas now form together a 18,3-hectare refuge for nature.

The Kyöpelinvuori area, located in Mäntyharju, was given an additional section in 2019, when Pro Luontokuva donated the 1.3 hectares this association had protected of the Kyöpelinvuori area, its underforest and meadow. The gift was more than welcome because the slope of the mountain and the forest underneath belong to the most valuable parts of the area.
