Steilene

Steilene is a group of five small islands located in the inner Oslofjord just west of Alværn on the Nesodden peninsula in Viken (formerly Akershus) county, Norway. The islands—Per- and Landsteilene (with a guest harbour), Storsteilene (with a natural harbour), Knerten (a bird reserve), and Fyrsteilene—are protected as a public outdoor recreation area and feature historic buildings reflecting coastal culture. In summer they are visited by a ferry from Alværn, and the former lighthouse on Fyrsteilene now serves as a coastal lodge managed by Oslofjordens Friluftsråd, with ongoing cultural and nature education projects. Only on Knerten is landing restricted part of the year due to the bird reserve. Steilene also has a weather station and areas valued for heritage and nature conservation.
