The river is a tributary to the river
Tanaro, which is a tributary of the river
Po. Its source is in
Pian Marchisio, a large plateau of the
Ligurian Alps. It flows northwards digging the
Valle Ellero, which ends in the
Po plain near
Roccaforte Mondovì. The Ellero then follows its course through the plain turning NE, crosses
Villanova Mondovì (where it gets from
right hand the
Maudagna, its main tributary) and then after
Mondovì, with some
meanders, reaches
Bastia Mondovì where it joins the river
Tanaro.
