Bay Patreksfjordur branches into two smaller fjords, Patreksfjordur and Talknafjordur. A fishing village by the same name rests on the 15 km long and nearly 4 km wide bay, Talknafjordur. The mountains drop steep into the bay, the lowland stretches are small and narrow and short valleys cut into the interior plateau.
The trout and char river Botnsa discharges into the bay. Thermal activity has been discovered in a few places and is used for house heating and a swimming pool in the village.
