Saltvik is a municipality of Åland, an autonomous territory of Finland. The total area is 1 161,8km², of which 150,7km² is land, 4,7km² lakes and 1006,4km² sea.
The archipelago north of Saltvik is perhaps the most beautiful one in Åland. Closest to land are the big islands Boxö, Sommarö, Flatö and Ryssö. Beyond, the horizon opens up and after passing Saggö it is more or less unbroken.
