Île aux Nattes (Nosy Nato) is a small island immediately south of Île Sainte-Marie (Nosy Boraha) off Madagascar’s east coast, noted for sandy beaches and nearshore coral reef. The island is low-lying and compact, with most facilities concentrated near the narrow channel that separates it from Sainte-Marie.

Visitors come for sheltered swimming, snorkeling on the fringing reef and a quiet island atmosphere with a small number of guesthouses and beachside services. Local boats provide frequent short transfers to and from Île Sainte-Marie and the islands are commonly visited together.

Geographically the island sits off Madagascar’s eastern seaboard within Analanjirofo administrative area, at the southern tip of the larger Île Sainte-Marie.

  • Access and snorkeling: Short pirogue or boat crossings link the island to Île Sainte-Marie and the narrow channel between them is popular for short snorkel trips to nearby fringing reef areas.
