Sahanlahti boulder terrain and Tupavuori cave

Nearby Tupavuori is also one of the Saimaa Geopark sites. The granitized biotite-hornblende gneiss bedrock features a large boulder and crevice cave, whose hall-like space can be accessed through a crack. The cave was formed when horizontal and vertical crevices deepened as the continental ice plucked boulders from the rock. The cave is dark in places, so it is highly recommended that visitors bring a torch. The cave is also said to have been a hideout during the war.  One story has it that some of the troops that passed by the lake heard a child crying in the cave, but since the commander didn’t hear it, he ordered his troops to push on. The people hiding in the cave got off with a fright.

The marked path to the cave starts from Tupavuorentie road. The parking space for cars is a short distance away on the same road. The trail traverses forest terrain and there are climbs and descents along the way, so be sure to wear sturdy footwear and dress according to the weather.
