Following the trails of the Mapuche people across the Andes, in the summer of 1552–1553, the Spanish Governor of the Captaincy of Chile Pedro de Valdivia sent Spanish Conquistador 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.
