The Mitsio Archipelago in Madagascar : secluded islands north of Nosy Be

Located northeast of Nosy Be, off the northwestern coast of Madagascar, the Mitsio Archipelago lies in the heart of the Mozambique Channel. Grande Mitsio, its main island, is around 60 kilometres from Nosy Be. Approximately 12 kilometres long, it is surrounded by sixteen islands and islets, including Nosy Ankarea, Nosy Tsarabanjina, Nosy Lava, Nosy Toloho and the spectacular Four Brothers.

Largely volcanic in origin, the archipelago is characterised by basalt formations, beaches, coral reefs and rich marine ecosystems. But the Mitsio Islands are also inhabited, with a history closely linked to the Antankarana Kingdom.

An archipelago of many faces

Grande Mitsio lies at the heart of the archipelago. It stretches for around 12 kilometres and is about 3 kilometres wide, reaching an elevation of 206 metres. Several villages are scattered along its coastline.

Around it, the scenery changes dramatically from one island to another. Nosy Ankarea stands out for its rugged terrain and, at 238 metres above sea level, is the highest point in the archipelago. Tsarabanjina is known for its beaches and clear waters, while farther north lies Nosy Lava. Much more discreet, Nosy Toloho holds a special place in local history and traditions.

The Four Brothers offer a completely different landscape. These four imposing rocky islets, with their sheer cliffs, rise directly from the sea and provide a refuge for numerous seabirds.

Grande Mitsio also features a remarkable geological formation: on the southern part of the island, basalt columns form a striking series of long, almost vertical rock pillars created by the cooling of ancient lava flows.

Other, far less well-known islands and small islets complete the archipelago and contribute to the remarkable diversity of its landscapes.

An inhabited land steeped in history

The Mitsio Islands are far more than a remote group of islands. Grande Mitsio is home to several villages, and the archipelago holds an important place in the history of the Antankarana Kingdom.

Around 1840, Nosy Mitsio served as a refuge for King Tsimiharo and several thousand of his followers during conflicts with the Merina Kingdom. Royal tombs can still be found on Nosy Toloho and Nosy Lava, bearing witness to the cultural importance the archipelago continues to hold for the Antankarana people.

Remarkable natural heritage

Grande Mitsio and the surrounding islands are now part of the Ankarea Marine Protected Area. Coral reefs, rocky seabeds, beaches and a variety of coastal habitats support a rich marine biodiversity.

The waters around the Mitsio Islands are frequented by several species of dolphins and other cetaceans, including humpback whales, as well as a wide variety of fish and sharks.

Only a few dozen kilometres from Nosy Be, the Mitsio Islands reveal a striking archipelago where spectacular island scenery meets a rich history and a deeply rooted local identity.
