The largest settlement on Strandir, Hólmavík, has 302 residents and forms the municipality of Strandabyggð's urban nucleus. Situated near the mid-point of Steingrímsfjörður's fertile southern shore, it is surrounded by farmland.

Drangsnes sits at the northeastern point of Steingrímsfjörður, where it meets Húnaflói. The hamlet is the largest settlement in Kaldrananeshreppur despite having just 71 inhabitants. Several kilometers west of Drangsnes is , the site of a 17th-century Basque whaling station where whales were processed before being shipped.
