Andøya (Norwegian), Ánda (Northern Sami), or Ánddasuolu (Northern Sami)[1] is the northernmost island in the Vesterålen archipelago, situated about 300 kilometres (190 mi) inside the Arctic Circle.

The main population centres on the island include the villages of Andenes, Bleik, and Risøyhamn.

Besides the flat and largely continuous bog areas, Andøya also consists of steep mountain ranges reaching up to 700 metres (2,300 ft) high.

The sharp peak of Kvasstinden is the highest point on the island at 705 metres (2,313 ft).

[3] A 10,000-hectare (25,000-acre) area comprising low-lying boggy ground in central Andøya, along with a stretch of the eastern coast and the lake of Skogvollvatnet on the west coast, has been designated an Important Bird Area (IBA) by BirdLife International (BLI) because it supports several thousand barnacle and pinkfooted geese on passage migration, as well as about ten breeding pairs of Eurasian curlews.
