Diego Ramírez Islands, Subantarctic archipelago at Cape Horn, Chile.
The Diego Ramírez Islands are a small archipelago off Cape Horn covering roughly one square kilometer with elevations reaching 179 meters above sea level. These islands divide into two groups separated by a three-kilometer passage, with six smaller islets to the north and larger landmasses to the south.
These islands were discovered in 1619 by the Spanish Garcia de Nodal expedition and named after cosmographer Diego Ramírez de Arellano. This early exploration connected this remote location to European mapping efforts in the far south.
The Chilean Navy operates a weather station on Isla Gonzalo where personnel gather data about conditions at the world's southernmost inhabited location beyond Antarctica. This station shapes daily life on the island and connects it to broader scientific efforts across the southern ocean.
Access to these islands is extremely limited because of their remote location and harsh southern conditions. Visitors should expect difficult weather and extreme isolation when approaching this region.
A new bird species called the subantarctic rayadito was identified in 2022 living exclusively on these islands. This discovery shows how much remains unknown about these remote locations.
