Hanifaru Bay, nestled within the UNESCO Biosphere Reserve of Baa Atoll in the Maldives, is a renowned marine sanctuary celebrated for its extraordinary gatherings of manta rays and occasional whale sharks. This protected bay, measuring approximately the size of a football field, serves as a vital feeding ground for these gentle giants, particularly during the southwest monsoon season from May to November.
The bay’s unique topography—shaped like a keyhole—plays a crucial role in concentrating plankton, the primary food source for manta rays. The interplay between the monsoon currents and lunar tides funnels nutrient-rich waters into the bay, creating a “plankton soup” that attracts large numbers of mantas and, on occasion, juvenile whale sharks. During peak feeding times, snorkelers can witness mesmerizing displays as mantas perform synchronized barrel rolls and form “manta trains,” spiraling in unison to maximize their feeding efficiency.
Access to Hanifaru Bay is strictly regulated to preserve its delicate ecosystem. Only snorkeling is permitted within the bay to minimize human impact, and all activities are conducted under the guidance of authorized operators. The best time to visit is between late July and early October, coinciding with the peak plankton blooms and optimal feeding conditions. During this period, it’s not uncommon to encounter up to 200 manta rays in a single session.
For those seeking an unforgettable marine experience, Hanifaru Bay offers a rare opportunity to witness one of nature’s most spectacular underwater phenomena. Whether you’re an avid snorkeler or a marine life enthusiast, the bay promises a serene yet exhilarating adventure amidst some of the ocean’s most majestic creatures.
