Paarlahti
Paarlahti is Finland's only fjord, and it is situated in Teisko, in Kämmenniemi in the lake of Näsijärvi. Paarlahti is about 10 km long and has a maximum depth of about 60 m.
Paarlahti has been called the longest inland fjord of Scandinavia, although it does not really resemble the large fjords of Norway. However, its long and narrow shape, its depth and steep shores qualify it as a fjord. Usually there are no islands in a fjord, but Paarlahti has a few. In Lake Inari in Finnish Lapland however, there are several bays that carry the word vuono (the Finnish word for fjord) in their names.
