Islotes de Puñihuil Natural Monument, Protected natural area in Chiloé Island, Chile.

Islotes de Puñihuil is a protected natural area comprising three small islets off the western coast of Chiloé Island. These islands serve as important nesting and resting grounds for numerous seabird species.

The islets are managed by CONAF as a Chilean Natural Monument. A 2007 study by the Alfaguara project, which works on blue whale and marine conservation in the area, led ecotourism boat operators to form an association and cut the number of penguin-watching trips to the islands. Since 2009 a municipal ordinance has limited daily visits and set conditions for them.

The fishing community at Puñihuil has integrated guided boat tours into their traditional practices, allowing visitors to observe seabirds up close. This has become a natural part of coastal life here.

The islets lie about 28 kilometers southwest of Ancud, where boat operators offer tours to the site. It is best to book tours during calmer weather, and options may vary by season.

This is the only place on Earth where Humboldt and Magellanic penguins establish nests in the same territory. This rare coexistence makes the site exceptionally important for bird watchers and wildlife enthusiasts.
