It is situated in the river Churún, an affluent of the Carrao. Tourists sometimes refer to this stretch of the river as the Auyan Tepui river but the river that culminates in the drop is the Kerepakupai-merú. In the indigenous Pemón language Kerepakupai-merú means "waterfall of the deepest place". The falls is also referred to as Churún-merú, an error, since that name corresponds to another Waterfall within the Canaima National Park. Churún in indigenous Pemón language means "thunder".
