The landscape is a combination of forests, fjords, and mountains. The highest mountain peak is Snota at above sea level. Other mountains include Vassnebba, Indre Sula and Ytre Sula, Neådalssnota, and Trollhetta. The river Surna runs through the valley from the east to the west, and forms a large delta where it enters the fjord near Surnadalsøra and Skei. This river is rich in salmon, which attract tourists from the rest of the country and abroad. The lakes Foldsjøen and Gråsjøen lie along the border with the municipality of Rindal in the east. The Grønkjølen Nature Reserve lies in the extreme northeast of the municipality.
