Mandalselva, also called Marna, is a river in Agder.
It has its sources in the mountains between Ose in Setesdal and Øvre Sirdal. The Mandalselva itself originates from Ørevatn (260 m above sea level) and flows south through the municipalities of Åseral, Sveindal, Marnardal and Mandal, until it flows into the sea/Mannefjord. at Mandal.
This river runs past my garden and therefore my walks and bike rides are mostly next to it.
