The Lyngen Alps (Norwegian: Lyngsalpan or Lyngsfjellan, Northern Sami: Ittuvárit, Kven: Yykeänvaarat[2]) are a mountain range in northeastern Troms county in Norway, east of the city of Tromsø.

In the lowlands on the eastern side of the Lyngen peninsula, mica schists, phyllites, and dolomites are mainly found.

Except for ice caps at the summits of Jiehkkevárri and Bálggesvárri, cirque glaciers dominate the present glaciation on the Lyngen Peninsula.

The Lyngen Alps are sufficiently high as to give rain shadow in the interior lowland areas east of the mountains.

The Lyngen Alps Landscape Reserve (Norwegian: Lyngsalpan landskapsvernområde) was established by the King of Norway on 20 February 2004 to protect one of Norway's characteristic mountain areas, which includes glaciers, moraines, valleys, and geological deposits, with biodiversity, cultural monuments, and cultural influences that characterize the landscape.

The protection of natural resources within the landscape reserve is also important for the Saami culture and economy, and the site must be suitable for reindeer herding.

There is a public transport connection between Tromsø and Lyngen via express boat to Nord-Lenangen and several bus routes.

One of the main tourist attractions of Lyngen Alps is the glacier-fed lake Blåvatnet with a distinct turquoise color, located in Strupskardet valley.

They consist of large angular boulders with diameters of 1–5 m. These moraines were formed by ice from the east and west Lenensbreen glaciers, with areas of 1.4 km2 and 0.7 km2 respectively.

The Alpine central part of Lyngen is made up of gabbro and other hard rocks that resist erosion and weathering well.

Gabbro forms when molten magma becomes trapped beneath the Earth's surface and slowly cools into a crystalline mass.

[13] The Caledonian Orogeny, which stretches from Arctic Norway through Great Britain, Ireland, and parts of Greenland, was formed as a result of the collision of the ancient continents Laurentia and Baltica 380–430 million years ago.

The Lyngen Peninsula is dominated by a 100 km slab of gabbro, lamellar diabase dikes, and other basic igneous rocks.

Most of the loose rock on the Lyngen Peninsula is moraines and glacial material transported by the melting of the ice sheet.

After the ice age, various glacial activities were observed in the mountainous regions, which affected the landscape to a lesser extent.

The rivers in the valleys carried the loose masses to the sea, the waves eroded and sorted the sediments in the constantly sinking beach area, and clay was deposited on the seabed.

The balance of the mass of glaciers and nearby areas ahead are climate archives that can tell about natural changes from the recent past and the current situation.

[4] The area around Lyngen is located in the heart of the Cap of the North (Norwegian: Nordkalotten) on the border with Sweden and Finland.

The way of life of the Sea Sami in this area was based on a combination of several types of crafts that ensured survival.
