Liehtalanniemi is a rocky-shored peninsula with typical mica gneiss bedrock. Glacial grooves running from north-northwest to south-southeast and depressions eroded by waves are visible on the shore’s rocks. There are also a few erratics and some small mounds of weathered rocks on the shore. There is a small museum estate in the traditional landscape of Liehtalanniemi. There is also a nature path with informative signs leading along the rocky shore.
