Île Sainte-Marie, known as Nosy Boraha, is located just off the east coast of Madagascar and offers a completely different atmosphere compared to places like Nosy Be or the dry beaches of the southwest. It is wetter, greener and noticeably slower. The island stretches in a long narrow shape along the Indian Ocean, with coconut palms leaning over the roads, old wooden houses disappearing behind thick vegetation and the smell of damp earth mixing constantly with sea salt and wood smoke after rain.
Rain is part of daily life here. Sudden tropical showers can soak everything for twenty minutes and disappear just as quickly. Roads dry fast. Laundry usually doesn’t.
The sea changes depending on which side of the island you stand. The eastern coast faces directly toward the Indian Ocean and can feel rough, windy and grey-blue during austral winter. The western side stays calmer thanks to the coral reef protecting shallow lagoons around parts of the island.
Most travelers stay around Ambodifotatra, the island’s main town, or continue south toward quieter beaches and small hotels hidden between coconut trees and ravinala palms. Across a narrow lagoon lies Île aux Nattes, one of the calmest corners of the region. There are practically no real cars there. Sandy paths, bicycles and fishermen crossing by dugout canoe. In some places the water stays shallow enough to walk absurdly far at low tide.
People come to Sainte-Marie for the beaches of course. But mostly they come for the whales.
Brief History
Long before tourism, Île Sainte-Marie already occupied an important position along Indian Ocean trading routes linking Madagascar, East Africa and Asia. Arab merchants likely stopped here centuries ago and later the island became famous as a refuge for pirates during the 17th and 18th centuries.
Protected bays, fresh water and strategic location made the island ideal for ships crossing the Indian Ocean. Pirate stories still circulate everywhere around Sainte-Marie. Some exaggerated over time obviously, but the connection is real enough. The old pirate cemetery near Ambodifotatra still exists today even if humidity and salt air have slowly damaged many of the tombs.
What makes the island historically unusual, though, is its relationship with France.
Unlike most of Madagascar, Sainte-Marie entered French control very early. In 1750, Sakalava queen Bety ceded the island to the French crown, reportedly seeking protection against rival Malagasy groups. Because of that agreement, Sainte-Marie technically became French territory more than a century before mainland Madagascar itself was colonized in 1896.
That separate status followed the island for a long time.
Even around Madagascar’s independence in 1960, discussions occasionally resurfaced about whether Île Sainte-Marie should remain tied to France because of its earlier colonial status. In practice, though the island became fully integrated into independent Madagascar together with the rest of the country.
Later came plantations. Cloves, vanilla, coffee. Some old colonial buildings and plantation houses still survive inland, partly hidden beneath tropical vegetation.
What Not to Miss
Between June and September, humpback whales migrate through the channel separating Sainte-Marie from mainland Madagascar. That migration turned the island into one of the country’s best known destinations. Whale watching trips leave every morning during the season and sightings are extremely frequent. Sometimes whales breach surprisingly close to the boats. Other days you hear them before seeing anything.
Île aux Nattes remains one of the highlights of the island. White sand, shallow lagoons, fishing canoes resting directly on the beach and small hotels hidden between palms.
The pirate cemetery near Ambodifotatra remains touristy but still interesting because of the island’s strange maritime history.
Further north, natural swimming pools and small hidden coves appear along the coastline, especially during low tide.
Inland, roads cross villages, clove plantations and humid tropical vegetation where ravinala trees grow almost everywhere. The atmosphere feels very different from western Madagascar. Greener, heavier, more humid.
