Satamosaari island is located along the shipping lane between Lappeenranta and Imatra. The island is a sand and gravel formation of glacial river with soils and various shorelines. The sheltered lagoon of Satamosaari has been created by the melting of a block of ice buried in sand, meaning it is a large kettle open on one side.

Satamosaari is part of a delta formation whose deposits were shaped by a number of ice blocks. Satamosaari’s lagoon-like bay, for example, indicates the location of a chunk of ice during the deposition period, and the island also features a few kettles. The ancient Greater Saimaa shoreline (80msl) is visible along the island’s entire shoreline.

Satamosaari is a recreation site of  the South Karelian Foundation for Recreation Areas. The island has a harbor, three campfire sites, two saunas, a Saimaa Geopark sign and instructions. Cruises from the Imatra are being organized to Satamosaari. Otherwise, the island can only be reached by boat or canoe.
