Villa O'Higgins has a diverse flora, where the forests of lenga, coigüe and ñirre are the most abundant, as we can see in the Mosco Glacier Park. Also because of the prevailing hydrography, we can find many "mallines" or wetlands nearby.

As for its native fauna, where the huemul stands out, foxes, pumas, and large and diverse numbers of birds and amphibians live, about which you can learn more by visiting the Mosco Glacier Park
