Key facts about Troms

Archipelagos, fjords and mountains create the frame for the county of Troms with added colour from the midnight sun and northern lights.


Troms has a varied coastline. Norway's two largest islands are located here, while the fjords virtually cut into the landscape. Mountains rise wildly and inaccessibly directly from the sea into the sky and are alluring for keen mountain hikers. Rivers and streams flow down the mountainsides and continue through expansive agricultural areas. Troms' many watercourses are ideal for exciting fishing and paddling experiences.


The eldest traces of human settlement in Troms are more than 10,000 years old and originate from a nomadic culture. Troms is also home to the world's northernmost traces from the Viking era.

The rich maritime resources combined with agriculture, created the basis for the first permanent settlement in Troms. The indigenous Saami population has always utilised the coast as summer grazing areas for their reindeer herds and the border areas with Sweden and Finland as winter grazing areas.

The interior of Troms was settled by farmers from places such as the Gudbrandsdalen Valley who took their culture northwards. The Kvens, people of Finnish stock, also settled in the county and their building style and culture is visible in several places.

The City of Tromsø has always been a starting point for polar expeditions and the world's northernmost university gives it an even more international flavour.


The county of Troms has a population of 154,642 and includes three cities/towns. The largest city is Tromsø with a population of 65,286, followed by Harstad with 23,105 inhabitants and Finnsnes with 11,160 inhabitants. The county's 22 municipalities contain many villages and smaller settlements.

Summer temperatures vary from 50 degrees Fahrenheit to well over 68 degrees Fahrenheit and make the area very fruitful.
