Lammassaari Island has well-functioning harbour services and an extensive network of trails, with campfire sites and beaches.
Lammassaari Island offers three time domains to thoude interested in the history of landscapes. On these trails, you can find samples of ancient bedrock, for example, and the island itself is a result of glacioflluvial deposition. The ancient shores aroudn the island constitute the third time domain. They tell of the history of the lake scenery, from the early ice-lake phases to the present day. The Stone Age habitats found near the ancient shores also show that people had found their way to Lammassaeri Island a long time ago. Lammassaari Island is a delta area belonging to the ice margin formation of the First Salpausselkä Ridge. Its deposition began some 12,300 years ago, when the mouth of a glaciofluvial tunnel stream opened into a crevasse at the margins of the melting ice sheet, an further into a glacial bay.
