Vasikkasaari, located on the west side of Santahamina in Helsinki, is a recreational island of about 18 hectares. The island is available for the city residents’ recreational use, and it also has summer residents with small cabins.

Calvholmen and Kalfholm were the first names of Vasikkasaari in mid-17th century, when it was part of the village of Santahamina. This name indicates that it was used as a pasture, as were several other islands in the Helsinki archipelago.
