The Baa Atoll UNESCO Biosphere Reserve hosts the largest known manta population on the planet, with 4,265 reef manta sightings recorded in the 2025 season alone.
Hanifaru Bay in Baa Atoll is a natural plankton funnel during the southwest monsoon, and manta rays gather there by the dozens to feed in cyclone formations. The bay’s unique geography concentrates krill-rich water, turning a small patch of ocean into one of the most reliable manta aggregation sites on Earth. This guide covers the best sites, permits, and timing for swimming with manta rays in Baa Atoll, with practical details for families and first-timers.
Hanifaru Bay offers the most reliable manta ray encounters in the world, but permits are capped at 80 visitors per day and the season runs June through October — advance planning is essential, and July to September gives you the best odds of seeing feeding chains.

Hanifaru Bay Snorkeling
Hanifaru Bay is the centrepiece of manta ray tourism in Baa Atoll, and for good reason. During peak season the bay can hold dozens of reef mantas simultaneously, performing barrel rolls and cyclone feeding as they strain plankton through their gills. The experience is regulated tightly to protect both the animals and the habitat, which is part of what makes it so special.
Permits cost around $20 per person and are required for all visitors. You must enter with a licensed guide — no independent access is allowed. Maximum 80 permits are issued per day, with a cap of 20 people in the water at any one time. Reserve through your resort, a local operator in Maalhos, or via the Baa Atoll permit system at least two weeks ahead during July–September.
Most tours depart from Maalhos or Fulhadoo, which are local islands in Baa Atoll with frequent boat transfers to Hanifaru. The crossing takes 10–15 minutes. Aim to arrive between 10:30 a.m. and 11:00 a.m. — best viewing hours run roughly 11 a.m. to 3 p.m., when the light is strongest and plankton concentration peaks.
You get a maximum of 45 minutes in the water per session. No diving is permitted — only snorkelling. Life jackets are recommended, and you must not touch, chase, or block the mantas. The guides position you along the edge of the feeding zone so the mantas pass within arm’s reach naturally. Each manta has a unique ventral spot pattern, like a fingerprint, which researchers use to track individuals.
Return to the jetty and dry off — most half-day tours include a light snack or coconut water. If you’re staying on a local island, you can easily visit again on a different day if permits are available. The night snorkelling trips in the Maldives offer a completely different view of the reef after dark, though mantas are less common then.
Dharavandhoo Thila and Other Baa Atoll Sites
Hanifaru Bay gets the attention, but Baa Atoll has several other manta cleaning stations and feeding sites that are worth your time, especially if Hanifaru permits are full. Dharavandhoo Thila, Nelivaru Haa, and Horubadhoo Thila (often called Manta Point) all host regular manta activity outside the peak plankton months.
Dharavandhoo Thila is a coral reef structure about 10 minutes by boat from Dharavandhoo island. It works best during the northeast monsoon (December–March) when mantas visit cleaning stations. Nelivaru Haa and Horubadhoo Thila are better in the southwest monsoon (June–October). Check with local operators which site is active when you visit.
These sites are deeper than Hanifaru Bay — Dharavandhoo Thila drops to around 12–15 metres — so you’ll want a guide who knows the currents. Snorkelling is possible at the reef top, but diving is more common here. Operators in Dharavandhoo and Maalhos run trips daily. The freediving scene in the Maldives is growing fast, and these thilas are popular spots for breath-hold divers too.
Currents at thila sites can be strong, especially during tide changes. Slack tide — the 30-minute window between ebb and flow — offers the calmest conditions and the clearest water. Ask your guide to check the local tide table before you go. A waterproof action camera with good stabilisation is handy here, because the water movement can make handheld footage shaky.

Choosing Your Baa Atoll Base
Where you stay in Baa Atoll determines how much time you spend on the water and how easy it is to reach the manta sites. The two main options are luxury resorts with dedicated manta conservation programmes and local islands with community-run tourism.
Resorts like Soneva Fushi and Four Seasons Landaa Giraavaru run their own manta conservation programmes and offer direct seaplane transfers from Malé (30–40 minutes, roughly $700–850 per person return). Local islands such as Maalhos and Fulhadoo give you cheaper access to Hanifaru Bay and a more authentic Maldivian experience, with guesthouses starting at a fraction of resort prices. If you’re still weighing which side of the atoll to sleep on, this interactive map of Baa Atoll’s hotels and guesthouses makes it easier to compare distance to the bay against room rates.
From Maalhos, boat transfers to Hanifaru Bay take about 10 minutes and cost around $20–30 per person with a group. Resorts provide their own excursions, usually included in the room rate or offered as a premium add-on. The Sun Siyam resorts in the Maldives operate a manta alert system that notifies guests when rays are spotted near the property, which can save you a boat trip.
Manta activity is highest mid-morning to early afternoon, so plan your water time around 11 a.m. to 3 p.m. On local islands, you can combine a morning manta trip with an afternoon visit to a bikini beach or a guided walk through the island’s village. If you’re looking for other ways to experience the atoll’s marine life, underwater scooter safaris are a fun alternative for non-snorkellers in your group.
Planning Your Manta Ray Day
A successful manta snorkel comes down to a few practical details that can make or break the experience. Here’s what to sort out before you hit the water.
Permits and Regulations
Hanifaru Bay permits cost around $20 per person and are issued for a 45-minute in-water session. The daily cap is 80 visitors, with a maximum of 20 people in the water at once. Permits are tied to a licensed guide, so you can’t book independently. July through September is the busiest period — bookings often fill 2–3 weeks ahead. The Baa Atoll manta season guide has a full breakdown of the rules and recommended operators.
What to Pack
A rash guard or lightweight wetsuit (2–3mm) is useful — the water is warm, but sun protection is essential, and a suit adds a layer of buoyancy. Reef-safe sunscreen is mandatory in the Biosphere Reserve. A mask and snorkel you’ve used before is better than rental gear that might leak. For capturing the experience, a compact action camera with good stabilisation works well in the moving water of the bay. The 360-degree cameras popular for travel vlogging let you reframe your shots later, which is handy when mantas appear from unexpected angles.
Safety and Etiquette
Manta rays are harmless to humans — they are filter feeders with no stingers or teeth. The real risks are sun exposure, dehydration, and boat traffic. Listen to your guide’s briefing on where to position yourself and how to avoid blocking the mantas’ feeding path. Never touch a manta ray; the oil from human skin can damage their protective mucus layer. Life jackets are recommended even for strong swimmers, especially if you’re visiting during the choppier months of July and August.
Lunar cycles affect plankton concentration, and manta activity drops significantly around the full moon when plankton is more dispersed. Check the moon phase before booking — a new moon or first-quarter moon typically gives the best feeding aggregations in Hanifaru Bay.
Before You Go: Baa Atoll Manta Ray Questions Answered
When is the best time to see manta rays in Baa Atoll?
Manta season runs June through October, driven by the southwest monsoon and the plankton blooms it stirs up. Peak viewing is July through September, when Hanifaru Bay sees the highest concentration of feeding rays. The 2025 season recorded 4,265 reef manta sightings, and the 2026–2027 forecast predicts similar numbers.
Do I need to be a strong swimmer?
For Hanifaru Bay, a basic comfort level in the water is enough — the bay is shallow (3–5 metres), and life jackets are recommended. The real challenge is staying still and letting the mantas come to you. For thila sites like Dharavandhoo, stronger currents mean you should be a confident snorkeller or stick to guided tours that provide flotation devices.
How do I book a permit for Hanifaru Bay?
Permits are arranged through a licensed guide or tour operator. If you’re staying at a resort, they’ll handle it. If you’re on a local island, guesthouses in Maalhos and Fulhadoo can book permits on your behalf. You cannot buy a permit at the bay — it must be pre-arranged. The $20 fee is paid upfront, and you’ll need to provide your passport details.
Is the experience suitable for children?
Yes, but it depends on the child. Lily was seven when we went, and she handled the 45-minute session fine with a life jacket and a shortie wetsuit. The mantas are large (up to 7 metres across) and move slowly, so they’re not intimidating. Younger children or those nervous in open water may prefer a shorter private tour or a resort-based manta experience with a dedicated guide.
What happens if the weather is bad?
Boat trips to Hanifaru Bay are cancelled in high winds or heavy rain, and permits are typically refunded or rescheduled. The bay is exposed to the prevailing wind, so choppy conditions can reduce visibility to a few metres. If your permit gets cancelled, consider a sustainable land-based activity in the Maldives instead, such as a coral planting workshop or a guided island walk.
