The Suganda Bay is about 8 miles (13 km) long and 2,2 miles (4 km) wide at the mouth. It is rather shallow, especially near the village Sudureyri. Steep mountains frame it, and the main lowland area is in the valley at the end of the bay. Avalanche danger is great.

Some geothermal activity enables the villagers to heat their houses with natural hot water. This area was very isolated before the tunnels to Isafiord and Flateyri were opened in 1995, as the mountain road was rarely passable in winter. Lignite strata exist near the farm Botn and were exploited in the past (the last time 1940-1942).
