Nosy Iranja
Nosy Be Archipelago · Madagascar

Nosy Iranja

Two islands connected by a kilometre-long sandbar at low tide, reached only by boat from Nosy Be. The defining image of Madagascar's northern coast.

At low tide, a ribbon of white sand emerges from the Mozambique Channel, connecting the forested islet of Nosy Iranja Be to its smaller twin. This sandbar, over a kilometre long, is the island’s signature. Unlike the bustling beaches and villages of Nosy Be, Iranja is defined by its quiet and its temporary geography, a place that changes its shape with the tide twice a day.

Reaching Nosy Iranja requires a dedicated boat transfer from Nosy Be, a journey of 90 minutes to three hours depending on sea conditions and the vessel. A day trip allows for several hours on the sandbar and in the lagoon, timed to coincide with the low tide. For those staying overnight, the experience shifts as the day-trippers depart, leaving the island to a handful of guests and the sea turtles that frequent its shores.
