The Puelo River has its origin in Lake Puelo in Argentine, and flows north-west through the Andes into Chile and the Reloncaví Estuary of the Reloncaví Sound at the northern end of the Gulf of Ancud.

A part of the northernmost border of Pumalín Park approximately parallels the course of the Ventisquero River.

A large northern tributary of the Puelo, the Manso, has its sources in Mascardi Lake and other lakes and streams south-east of the Cerro Tronador, also in Argentina, and flows south-west through the Andes to unite with the Puelo a few kilometers west of the 72nd meridian.
