"Ancient shoreline embankments circle Lauhanvuori Hill. The largest of these stone fields, called Kivijata ("Stone Chain"), is 800 metres long. The bedrock at Lauhanvuori is sandstone, which is quite rare in Finland. Only on these stone fields it is exposed, elsewhere it is covered in moraine, turf or sand.

Hiking over the stone field is only allowed on the duckboards. In winter when the stones are covered by snow you may cross Kivijata walking outside the duckboards." Source: Metsähallitus / Forest And Park Service
