Desventuradas Islands, Remote Pacific archipelago in Insular Chile
The Desventuradas Islands form a small archipelago of four oceanic islands roughly 850 kilometers off Chile's Pacific coast. The group includes San Ambrosio and San Félix as its main islands, sitting far from any shipping lanes or populated areas.
Spanish navigator Juan Fernández discovered the islands in 1574 while exploring the Pacific Ocean. He named them after saints Felix and Ambrosio, names that have remained through the centuries.
The islands host a small naval garrison on San Félix that represents Chile's sovereign claim over this remote territory. This minimal human footprint has helped preserve the native wildlife and ecosystems in an otherwise untouched state.
Access is restricted to organized scientific expeditions coordinated by the Chilean Navy. Weather conditions and ocean swells significantly affect when the islands can be safely reached.
The waters surrounding the islands host marine life more connected to South Pacific ecosystems than to mainland Chile. The Humboldt Current shapes water temperatures and determines which ocean species thrive in this remote location.
