Grankullaviken (or Grankullavik) is a shallow[1] bay at the northern tip of Öland, Sweden, located in Böda socken, Borgholm Municipality.
The lighthouse Långe Erik on the Stora grundet island is officially named Ölands norra udde (Öland's northernmost point), even though the western headland extends a bit further north than the island upon which it stands.
This part of Öland was an important landing point for merchants in northern Kalmar County, and much of the shipping toward Gotland passed through this area as well.
[2] Ferry service since 1959 was provided intermittently by the converted cargo ship Nordpol, sailing between Nabbelund and Gotland (Klintehamn or Visby).
[4] Grankullaviken's sheltered location is attractive to fishermen who fish mainly for pike, bass, and trout, besides garfish, flatfish, sik, and ide.
