The Petrohue River is born in the Todos los Santos lake and flows into the Reloncavi estuary, where it gives its name to the Reloncavi basin.
This river has a length of 36 km, and in the bed of the river we can find attractions such as Saltos del Petrohue, great fauna and forests.
The Petrohué River is considered one of the best both nationally and internationally for sport fishing given the great diversity of species and their optimal conditions for wading and float fishing.
