Frösön

Frösön is a 41 square kilometre island in Storsjön or Lake Storsjön, connected to the mainland by three bridges, one of which connects the island to Östersund called Frösöya in the local dialect of Jamish.

Frösøen consists mostly of rocks, and the island's nature is relatively hilly. The highest point on the island is Östberget and it reaches an altitude of 469 metres above sea level, and 176 metres above Lake Storsjön.

The surrounding countryside consists of large forests and fields. As a result, there is a rich wildlife, including moose and deer, which also migrate across the ice in winter and stay on the island when the ice melts again in spring.

In the south-western part of the island lies the famous bird lake, Ändsjön, and the area is also a nature reserve.

Frösön is home to the old castle Mjälleborgen and the famous Frösö Stone, which is also the world's northernmost rune stone. Viking coins from the English Isle of Man have also been found on Öneberget.

Östersund Åre Airport is located on Frösön.
