Sognesjøen is a
strait in
Sogn og Fjordane county,
Norway. The strait is the outermost part of the large
Sognefjorden. It runs along the border between
Solund and
Gulen municipalities. The long strait begins around the village of
Rutledal on the mainland of Gulen at the mouth of the Sognefjorden. The strait then flows in a southwesterly direction into the
North Sea, just north of the island municipality of
Fedje (in
Hordaland county). The Sognesjøen is surrounded by many large and small islands. The islands of
Sula,
Steinsundøyna,
Ytre Sula lie along the northern side of the strait. The mainland and the islands of
Hiserøyna, Hille, Kversøyna, and
Byrknesøyna lie along the southern side of the strait.
