Perched by Sandvatnet and rebuilt in 2010, Sandvasshytta is Haugesund Turistforening's oldest mountain cabin in the Etnefjell region. The self-service lodge offers 62 beds, remains unlocked and open year-round, and guests are responsible for kitchen tasks, fetching water, and cleaning. Accessible via a marked trail from Markhus at Øvra (about a 4-hour walk), the cabin provides rowboat access, some phone-free solitude, storage for dogs, and a nearby Viking grave to explore.
