The waterfalls of Ramil, in Rus, and of Saint Paio, in Entrecruces, jump in the Meridian Depression. This succession of waterfalls is one of the geological phenomena more important of Galicia. It crosses it from the seaboard of Carballo until Tui. The route of the waterfalls (PRG-142) begins in Brea and finishes beside the waterfall of Entrecruces, where the river Outón precipitates to the empty from more than 40 metres of altitude.
