Introduction
Baa is a ring of about seventy-five islands in the western Maldives, thirteen of them inhabited, and it is the only part of the country designated a UNESCO Biosphere Reserve. The reason is a small dead-end bay called Hanifaru, where the monsoon current corners plankton against a closed end of reef and manta rays arrive in numbers seen almost nowhere else on earth.
Overview
For most of its history Baa was known within the Maldives for lacquerwork and boatbuilding and to nobody outside it. That changed when the manta aggregation at Hanifaru Bay became widely known, and the atoll now carries both a UNESCO Biosphere Reserve designation and a cluster of resorts that came for the marine life. It sits far enough from Malé to need a seaplane or a domestic flight, close enough that the journey is straightforward, and it has an unusual mix for the Maldives: high-end resort islands and a genuine guesthouse scene on inhabited islands within the same lagoon system. The manta season runs with the south-west monsoon, broadly May to November and strongest in the middle of that window, which is exactly the half of the year most brochures advise against — cloudier, wetter, cheaper, and the only time the thing Baa is famous for actually happens. Come outside it and the atoll is a good Maldives destination with quiet reefs and an easy pace. Come inside it and you are in one of the great marine wildlife events, in warm water, wearing a snorkel.
Discover Baa
Hanifaru is not much to look at — a small bay closed at one end, no island, no beach worth the name. What matters is its shape. When the south-west monsoon drives current across the atoll, plankton is pushed into the bay and cannot escape past the closed end, and the concentration draws manta rays to feed in numbers that can run to the dozens and occasionally far beyond, sometimes joined by whale sharks. The Maldives diving guide explains why aggregations anywhere in this country are as predictable as they are; what belongs to Baa is the visiting. The bay is inside the protected core of the Biosphere Reserve and access is managed: rangers control how many boats and swimmers are in the water, there are time limits, and — the rule that surprises divers — scuba is not permitted. You snorkel. That restriction is not an inconvenience to be worked around, it is the reason the mantas still come; bubbles and depth disperse a surface-feeding aggregation quickly. Trips run from resorts and guesthouses across the atoll and depend on tide and current, so a booking is a booking for a window rather than a time, and a boat may turn around if the plankton has not arrived. Go early in your stay so there is room to try again.
Ways to Experience This Destination
Hanifaru Bay's monsoon-season aggregation, snorkel-only and ranger-managed, plus manta cleaning stations across the atoll.
The Maldives' only Biosphere Reserve — a managed core zone, reef systems, seagrass beds and the marine research that goes with them.
Uncrowded coral reef and pinnacle dives with turtles and reef fish, gentler than the channel sites of the central atolls.
Thulhaadhoo's lacquerwork tradition, the working atoll capital at Eydhafushi, and guesthouse islands with a real manta-season economy.
Fulhadhoo's long sandbank and the quiet southern islands, where the appeal is that there is nothing else there.
