Located in Espoo’s Suvisaaristo district, the 130-hectare Pentala is the highest island in Southern Finland. The island’s nature is particularly diverse, and approximately half of Pentala is a nature conservation area. Lake Pentalanjärvi in the middle of the island has rugged and steep shores. The island has a rich variety of animal life – you may for example glimpse a deer or a great spotted woodpecker in the diverse forest. Several rare plants grow on the naturally beautiful Diksand beach. Please remember that landing a motor ship at the Diksand beach is prohibited.

Today, about half of Pentala Island is owned by the City of Espoo. The majority of the city-owned land is located in the centre of the island. The museum area on the northeastern shore is located on land owned by the City of Espoo. There are several dozens of privately-owned summer cottages on the island’s shores. The seashore is only freely accessible from the museum area and the Diksand beach. 

The nature conservation area and paths of Pentala Island are the responsibility of the Environment Department of the City of Espoo.

The Pentala nature conservation area limits the ways the island may be used. You cannot build a fire or spend the night on Pentala Island.
