About Chonos Archipelago

The Chonos Archipelago is a large group of islands, islets, and channels off the southern Pacific coast of Chile in the Aysén Region. The area is characterised by rugged coastlines, deep fjords, and a maritime climate.

The archipelago offers extensive coastal wilderness, with temperate rainforest, shoreline wildlife, and navigable channels used by fishing and charter boats. Its remoteness makes it a destination for expedition cruising, fishing, and ecological observation rather than mass tourism.

The islands were historically used and navigated by indigenous coastal peoples and later visited by European explorers and Chilean settlers. Economic activity has centred on fishing, small-scale forestry, and marine transport.

The islands lie off the western coast of southern Chile within the Aysén administrative region, scattered along a long stretch of the southern Chilean fjord zone and accessed mainly by sea or limited regional air links.

  • Scale: Consists of numerous islands, islets, channels, and fjords stretching along Chile’s southern Pacific coast and is sparsely populated.
