The Vals River is a tributary of the Vaal River in the Free State, South Africa. It is a strong seasonal river. This river of the Middle Vaal System is a good place for fishing, especially the local Largemouth Yellowfish.
Etymology: Translated into Afrikaans from its Khoekhoe name Enta, Nta or Entaap, meaning 'false or treacherous river'; possibly referring to unexpected depths in its stream bed or to changes in its course during floods.
