About Sarigan

Sarigan is a small uninhabited volcanic island in the Northern Mariana Islands of the western Pacific Ocean. It is part of the Northern Islands Municipality and is noted for its steep terrain and natural habitats.

The island is volcanic in origin and supports seabird colonies and other wildlife; human presence is minimal and visits are restricted for conservation reasons. It has no permanent population.

Historically it has been visited episodically for resource use and by passing vessels, but it has not supported settled communities in modern times. Current management emphasizes habitat protection and limited scientific access.

Geographically Sarigan lies in the northern part of the Mariana island chain, north of Saipan and the main inhabited islands, within oceanic waters of the western Pacific.

  • Conservation status: Uninhabited and managed as a wildlife and seabird sanctuary with access controlled to protect breeding colonies and native habitats.
