Troms

Troms is located in the northern part of the Scandinavian peninsula. Due to the long distance to the more densely populated areas of the continent, this is one of the least polluted areas of Europe. Troms has a very rugged and indented coastline facing the Norwegian Sea. However, the large and mountainous islands along the coast provide an excellent sheltered waterway on the inside. Starting in the south, the largest islands are: northeastern part of Hinnøya (the southern part is in Nordland), Grytøya, Senja, Kvaløya, Ringvassøya, Reinøy, Vannøy and Arnøy. Some of these islands, most noteworthy Senja, have a rugged outer coast with steep mountains, and a more calm eastern shore. There are several large fjords that stretch quite far inland. Starting in the south, the largest fjords are Vågsfjord, Andfjord (shared with Nordland), Malangen, Balsfjord, Ullsfjord, Lyngen (the municipality has its name from the fjord) and Kvænangen (fjord). The largest lake is Altevatnet in the interior of the county.

There are mountains in all parts of Troms; the most alpine and striking are probably the Lyngen Alps (Lyngsalpene), with several small glaciers and the highest mountain in the county, Jiekkevarre with a height of 1,833 m (6,014 ft). Several glaciers are located in Kvænangen, including parts of the Øksfjordjøkelen, the last glacier in mainland Norway to drop icebergs directly into the sea (in Jøkelfjord). The largest river in Troms (waterflow) is Målselva (in Målselv), and the largest (not the highest) waterfall is Målselvfossen at 600 m (2,000 ft) long and 20 m (66 ft) high. There are limestone bedrock in parts of Troms, and thus numerous caves, as in Salangen and Skånland.
