Known as the gateway to the Helgeland coast – a spectacular stretch of mountainous coastline dotted with a myriad of islands – Sandnessjøen, on Alsta Island, is arguably most famous for its proximity to the striking Seven Sisters mountain range.[ReadMoreMob] According to legend, the seven side-by-side peaks are troll sisters who were turned to stone in the sunlight. Each mountain can be climbed individually, with peaks ranging from 910 metres (Breitinden) to 1,072 metres (Brotnkrona), or experienced climbers can take on the challenge of all seven. The views from the top of each peak are magnificent, offering vistas across Nordland and the Viga Archipelago. Outside of the Seven Sisters, the Petter Dass Museum is a local highlight, situated towards the south of the island of Alsta. Petter Dass was one of the country’s best-loved poets and also a priest, and the museum pays tribute to his life and works throughout a number of buildings, from the original 18th century vicarage to the modern museum building which overlooks the water.
