A set of small caves on a cliff of Brännbergen hill. The site can be visited quickly from a nearby bus stop (Rajaportti). Nearest houses are close, so avoid making noise or walking through private yards when visiting here. The path may get slippery when wet or icy conditions.

The flora of the herb-rich forest of Mustavuori is very diverse as the area's bedrock is rich in minerals that benefit fastidious plant species. The excavations carried out in connection with the construction of the area's fortifications have also released calcium and other nutrients into the soil. The bedrock at the center of Mustavuori features WWI-era trenches and three large excavated caves. The herb-rich forests of Mustavuori are home to a variety of songbird species, including wood warblers, jaundice warblers and blackcaps. The natural forests are also home to red-breasted flycatchers, hazel and black grouse. These types of forests also accumulate a lot of rotting wood, the presence of which is essential for a number of different species, including polypores. Therefore, the area has a wide range of polypores, including some rare species such as Anomoporia kamtschatica and Antrodia pulvinascens.
