Þistilfjörður, the bay between the Melrakkaslétta plain and the Langa­­nes peninsula, with farms along its head, where there are low hills and valleys with many rivers, the main ones being Svalbarðsá, Sandá, Hölkn­á, Laxá, and Hafralónsá. All rise in the moors and most have trout and salmon. Formerly there were several farms on the extensive moors farther inland.
