Kanaga Island
Island Aleutian island dominated by active stratovolcano Kanaga
Kanaga Island in the Aleutians centers on Mount Kanaga, a volcanic peak; travelers arrive for remote wildlife viewing, seabird colonies, fishing and rugged volcanic landscapes.
Kanaga Island is an uninhabited island in the Aleutian chain of Alaska, part of the Andreanof Islands. The island is dominated by a central stratovolcano, Kanaga, whose summit reaches roughly 1287 m.
The island’s landscape is volcanic, with steep slopes radiating from the central cone and coastal cliffs around much of the shoreline. There is no permanent civilian population and the island is visited mainly by researchers, occasional fishing or expedition vessels, and by monitoring agencies for volcanic activity.
Kanaga lies among the western Aleutians and is grouped with nearby islands such as Tanaga and Adak in a remote, maritime environment. The island is many hundreds of kilometres west of mainland Alaska and is accessible only by sea or specialized aircraft.

Tips for Visiting Kanaga Island #
- Treat Kanaga Island as remote wilderness: there are no regular tourist services, landings are weather-dependent, and the island is dominated by Mount Kanaga - check volcanic activity notices before planning a trip.
- If you need landing or access information, contact the appropriate Alaska authorities (e.g., Alaska Maritime National Wildlife Refuge or local borough offices) and plan transport via charter boat or plane rather than expecting scheduled services.
