The Marine World of Madagascar
Witness oceanic migrations and the conservation science working to protect them.
The sound of a humpback’s exhalation carries across the calm water of a sheltered bay. The whale has traveled from Antarctica to calve and nurse its young in these channels, a seasonal pulse that has defined this coastline for millennia. Months later, in a different part of the country, the world’s largest fish, the whale shark, glides through plankton blooms near the surface. Madagascar’s 5,000-kilometer coastline is a mosaic of protected bays, deep oceanic passes, coral gardens, and vast seagrass meadows. These habitats are critical corridors for migrating giants, nesting sites for five species of sea turtle, and the last refuge for one of the Indian Ocean’s most threatened mammals, the dugong. Few visitors ever witness the full scope of this marine system, which operates on a scale far larger than a single location or season.
Vivy Travel facilitates marine exploration by coordinating with a select group of dive centers and charter operators who adhere to strict codes of conduct for animal encounters. We can arrange for private charters with marine biologists or specialist guides who can interpret the behaviors you observe. Access to certain sensitive areas or participation in research-based activities depends on permits and the consent of conservation partners. Encounters with wild animals are, by their nature, never guaranteed. This approach ensures that your presence contributes to, rather than detracts from, the long-term protection of these vital marine ecosystems. For diving, proof of certification is required; snorkeling requires only basic swimming ability.

Humpback whale season is July through September, primarily on the east coast. Whale shark season is October through December, primarily in the northwest.
For scuba diving, yes. You will be asked to present your certification card (PADI, NAUI, SSI, etc.). Snorkeling does not require certification.
We work only with operators who follow strict codes of conduct, including minimum approach distances, no-touch policies, and engine cut-offs. The welfare of the animals is the primary directive.
Dugong sightings are exceptionally rare. They are shy, threatened, and live in specific seagrass areas. While an expedition can be organized to their habitat, a sighting requires immense luck and patience.
