Inspired by the landscape of Cautín and influenced by the southern poet Augusto Winter, Navarro wrote, at the age of seven, "La laguna de Trovolhue", one of her earliest poems.

Four years later, she joined the Grupo Fuego de la Poesía founded by José Miguel Vicuña and Carlos René Correa.

In 1965, Navarro's book, La ciudad que fue, was published by Editorial Universitaria and was awarded the Pedro de Oña prize.

On more than one occasion, she was a candidate for the National Prize for Literature and jurist in multiple poetry contests, including the Fondo del Libro y la Lectura.

One of them is Profesión de silencio (Profession of silence), in which she tackles injustice and pain from the repression suffered during the 1973-90 military dictatorship of Chile.
