Hanifaru Bay is best from July to October, and you book it four to six months ahead. Only permitted operators can enter, so you cannot simply turn up.
The bay is small and shallow, inside the Baa Atoll UNESCO Biosphere Reserve in the northern Maldives. When current-driven plankton fills it, reef manta rays (Mobula alfredi) arrive to feed, and on a productive day 100–200 of them are in the water at once.
The shape of Baa Atoll does the work. Water pushing through the outer reef channels funnels into the bay and carries the zooplankton the mantas eat.
When that lines up with peak plankton production in the southwest monsoon, the mantas arrive in numbers. The feeding events are predictable enough to plan a trip around.
When to go: June to November, peak July to October
The season follows the southwest monsoon, the weather most guides tell you to avoid. Don't avoid it. The rougher seas come with the plankton that draws the mantas.
| Month | Aggregations | Notes |
|---|---|---|
| June | Building | Mantas arriving, smaller aggregations |
| July | Peak | Strong and consistent |
| August | Peak | The best month for big counts |
| September | Peak | Still strong, with whale sharks active at the same time |
| OctoberNow | Tapering | Still productive as the season turns |
| November | Closing | Variable, but some aggregations still happen |
From December to May the bay is largely quiet for big aggregations. Cleaning-station mantas carry on across the central atolls all year, but the Hanifaru feeding is seasonal.
Visibility drops on high-plankton days. That is a good sign: the food is there, so the mantas are too.
For the full Maldives picture, see the Maldives diving guide and the best time to dive the Maldives. With good timing, the same trip can include whale sharks at South Ari Atoll.
What a feeding aggregation looks like
On an average peak-season visit, expect 20–50 mantas. On a productive day it is 100–200. Counts change with the current, the tide and the plankton, so treat them as a guide, not a promise.
The mantas here do not behave like the ones at a cleaning station. They are not circling the reef waiting for cleaner fish. They feed actively, mouths open and cephalic fins unfurled, moving through the water in coordinated patterns that follow the plankton.
The best-known version is cyclone feeding. Mantas form a spinning column, each following the one in front and rolling through the densest plankton at the centre.
A single cyclone can hold 20–40 mantas. When several form at once, the water is simply full of rays.
Snorkel the bay, dive the reefs around it
The bay is snorkel-only in season: scuba is not allowed. The feeding happens in the top 0 to 8 metres, where the plankton concentrates, and a snorkeller at the surface is in the middle of it.
Bubbles from scuba equipment have been seen to disturb the feeding and disperse the aggregations. Permitted operators run Hanifaru as a snorkelling excursion in season.
If the aggregation is why you came, go in with snorkel gear and let the mantas set the depth.
The diving is on the reefs around the bay. Baa Atoll sites such as Dharavandhoo Corner, for hammerheads, and the outer atoll walls are where the deeper diving shows. A liveaboard based in Baa usually combines snorkelling at Hanifaru with dives on the surrounding reefs.
Permits: not every operator can enter
Hanifaru Bay sits inside a protected biosphere reserve. The Maldivian government requires every operator entering the bay to hold a valid permit, and it caps how many people are in the water at once.
The bay has been a marine protected area since 2009, and the Convention on Migratory Species lists its rules as bans on scuba diving and fishing, a limit on the number of visitors and a maximum time in the bay (CMS). PADI's site page agrees: snorkelling only, diving banned in season, limited daily entries (PADI). Both pages checked 22 October 2026.
That is good for the mantas. It also means you will not share a peak-day aggregation with unlimited tourist groups.
The practical result: not every boat that sails through Baa Atoll can enter. Before you book, confirm that the operator holds a current Baa Atoll entry permit and lists Hanifaru Bay on the itinerary.
Why staying in Baa beats a day trip
You can reach Hanifaru on a day trip from Dharavandhoo Island, the nearest inhabited island with an airport in Baa Atoll, or on a resort transfer in the atoll. A Maldives liveaboard is significantly better, for three reasons.
- Timing. The aggregations are strongest in the early morning and late afternoon, when the current runs hardest. A boat anchored in Baa overnight can have you in the water at dawn. Day-trip visitors arrive later and leave earlier.
- More than one attempt. Quality changes day to day with current, tide and plankton density. Two or three days in Baa give you several windows. A day trip gives you one.
- A fallback. If the bay is not producing, a liveaboard guide can redirect to the outer reef dive sites. A day-trip visitor has few alternatives.
Book four to six months ahead
For July to October, book a liveaboard with a confirmed Hanifaru itinerary at least 4 to 6 months ahead. The best boats sell out completely. Last-minute space is rare, and it usually reflects a cancellation rather than unsold inventory.

What level you need
You do not need a dive certification to see the aggregation, because the bay is snorkel-only. The bay is shallow, 12 metres at most, with a gentle, consistent current during feeding. It is one of the more accessible wildlife encounters in the Maldives.
The dive sites around Baa Atoll ask for more. Advanced Open Water is appropriate for the channel and outer reef diving.
The hammerhead dives at Dharavandhoo Corner are early-morning blue-water dives with some current. Open Water divers should stay on the shallower reef systems.
Questions
When is the best time to visit Hanifaru Bay for manta rays?
July to October, with August and September the strongest months. The southwest monsoon drives the plankton blooms that trigger the aggregations. On the best days in peak season, 100–200 mantas have been documented feeding at once.
Can you scuba dive at Hanifaru Bay?
No. Hanifaru Bay is snorkel-only in season, and scuba is not allowed in the bay. The mantas feed in the top 0–8 metres, and scuba bubbles can disturb the feeding and break up aggregations.
For the reef and channel diving around Baa Atoll, scuba is appropriate. A liveaboard itinerary usually combines snorkelling in the bay with diving on the reefs.
Do you need a permit to visit Hanifaru Bay?
Operators need a permit; individual visitors do not arrange one themselves. Confirm that your liveaboard or day-trip operator holds a valid Baa Atoll entry permit and lists Hanifaru Bay access before you book. Not all Maldives boats are permitted.
How many manta rays can you see at Hanifaru Bay?
On an average peak-season visit, 20–50. On a productive day, 100–200. Counts change with the current, the tide and the plankton.
Can you visit Hanifaru Bay without a liveaboard?
Yes. Day trips run from Dharavandhoo Island in Baa Atoll, reached by domestic flight from Malé. A liveaboard gives you several visits, dawn access and a fallback if the bay is not producing, so for a dedicated Hanifaru trip it is meaningfully better.
How far is Hanifaru Bay from Malé?
Baa Atoll is about 100 kilometres north of Malé. You reach it by seaplane (about 25 minutes) or by domestic flight to Dharavandhoo Airport followed by a short boat transfer. Liveaboards leaving Malé reach Baa Atoll after an overnight passage.
