Limay River
The earliest discovery of Nahuel Huapi by the non-indigenous peoples is linked to the conquest of Chile. In the summer of 1552–1553, the Governor of Chile Pedro de Valdivia sent Francisco de Villagra to explore the area east of the Andes at the latitudes of the city of Valdivia. Francisco de Villagra crossed the Andes through Mamuil Malal Pass and headed south until reaching Limay River in the vicinity of Nahuel Huapi Lake.
