[3] Due to post-glacial rebound the land is rising at from 0.8 to 1 centimetre (0.31 to 0.39 in) annually, so the shoreline can retreat by as much as 100 metres (330 ft) in one person's lifetime.

[4] The archipelago is only 100 kilometres (62 mi) south of the Arctic Circle, so there is daylight for up to 24 hours in the summer, and moonshine may be visible all day in the winter.

Fingermanholmen is almost in the center of Piteå, accessible by boat or kayak in summer, and by ski in winter.

Other islands include Inre Mörögrund, Mosesholmen, Hällskäret, Stenskär, Stor-Räbben, Svinöra and Vargön.

The Bondöfjärden nature reserve is about 10 kilometres (6.2 mi) to the southeast of Piteå town.
