Guamblin Island

Parque Nacional Isla Guamblín is a nature reserve in the Aysén Region covering roughly 10,625 hectares of protected land entirely surrounded by the Pacific Ocean. The island features rocky coastlines, thick forests, and wind-shaped vegetation typical of southern Chilean fjords.

Juan Ladrillero first explored the island in 1557 during his maritime expedition along the Chilean coast. The Chilean Navy later renamed it Nuestra Señora del Socorro in 1880.

The Chono indigenous people lived on this island for centuries, adapting to harsh maritime conditions and using local resources for survival. Archaeological remains scattered across the landscape still reflect this ancient human presence.

The park has no visitor facilities and requires private boat transportation from Puerto Aguirre to reach the island. Access is challenging due to the exposed ocean location and often rough weather conditions.

From December through April, blue whales approach the island's coast within a few hundred meters, making it significant for marine research. Visitors may observe these ocean giants from shore during these months.
