Ullsfjorden is a
fjord in the municipalities of
Tromsø,
Karlsøy, and
Lyngen in
Troms county,
Norway. The fjord flows from Sjøvassbotn northwards along the west side of the Lyngen Peninsula (where the famous
Lyngen Alps are located). The Kjosen fjord branches off to the east side and the
Grøtsundet branches off to the west (which then flows into the
Tromsøysundet). The islands of
Reinøya and
Karlsøya lie along the western side of the fjord. The southern part of the Ullsfjorden is also known as
Sørfjorden. The area surrounding the Ullsfjorden was part of the municipality of
Ullsfjord for about 60 years during the 20th century.
