Name and location
Calbuco is located partly in Puerto Varas Commune and partly in Puerto Montt Commune. It lies 49 km from the city of Puerto Varas and 69 km from Puerto Montt. Its name is thought to come from the Mapuche words "kallfü" (blue) and "ko" (water), meaning "blue water". It shares the name with Calbuco Island in nearby Reloncaví Sound as well as the city and commune of Calbuco, although it is not located there.
