 The river meets a small stream close to Hilgershausen then flows southwest down to Helmshausen.After passing a mill, and two basalt quarries, the Rhünda reaches the Felsberg district of Rhünda, after it crosses under Bundesstraße 253, just before reaching the Main–Weser Railway at about above sea level.There it opens into the River Schwalm, which, in turn, just after passing again under the railway line, flows in the River Eder.
