About Sju søstre

Sju søstre is a group of seven mountain peaks on the island of Alsta in Alstahaug municipality, Nordland, Norway. The formation is a local landmark on the Helgeland coast known for its row of distinct summits.

The ridge offers exposed hiking and scrambling routes with panoramic views of the surrounding islands and the Norwegian Sea; the seven peaks are visible from the nearby town and ferry approaches. The area is used for day hikes and mountaineering rather than developed facilities.

The peaks are a natural formation that has provided a recognizable coastal landmark for local communities and mariners for centuries. The name and grouping have long featured in local folklore and navigation but the site has no constructed historical complex.

Located on the island of Alsta, the range overlooks the town of Sandnessjøen on the Helgeland coast of Nordland. The mountains sit on Norway’s coastal archipelago in northern Norway.

  • Seven peaks: Comprises seven named summits that form a distinctive serrated skyline on the island of Alsta.
  • Access and hiking: Accessible from the nearby town of Sandnessjøen with marked routes and scrambling sections suitable for experienced hikers.

Tips for Visiting Sju søstre

  • Arrive by late morning to combine a short hike with lunch at a local café-parking is limited and best used earlier in the day.

  • Be mindful of coastal winds; the islet group faces open sea and conditions can change quickly.
