Nosy Mitsio Archipelago

An archipelago of quiet, mineral islands north of Nosy Be, reached only by private boat for charter sailing, diving, and sport fishing.

The boat leaves the harbor at Nosy Be, and for several hours, the only markers are the volcanic outlines of distant islands. Nosy Mitsio is not a single destination but a constellation of quiet, mineral-sharp islets defined by what is absent: roads, villages, and the background noise of settled life. Unlike the resorts and towns of Nosy Be, the experience here is dictated by the sea, the wind, and the chart of a private vessel.

Access is exclusively by sea, typically as part of a multi-day private charter or cruise departing from Nosy Be. The crossing itself is part of the experience, filtering out day-trippers and preserving the archipelago’s quiet. The best conditions for sailing and diving are from May to November, when the seas are calmer and the weather is dry. A visit requires a minimum of three days to properly explore the different anchorages and dive sites.
