Up-close invitation to meet world’s largest known Manta Ray population at Four Seasons Maldives at Landaa Giraavaru
The Manta Trust team at Four Seasons Resort Maldives at Landaa Giraavaru is once again preparing for the greatest underwater show on Earth, and thanks to its intensely researched “hot dates,” marine adventurers can now maximise their chance to swim with the world’s largest-known manta ray population.
It’s one of the most exciting times of the year in the Maldives Baa Atoll UNESCO Biosphere Reserve. Between May and November, plankton-rich currents lure reef manta rays to local waters in their hundreds for graceful feeding frenzies. Having studied this group of gentle oceanic giants for nearly twenty years, the Manta Trust team at Landaa Giraavaru are best placed to offer extraordinary insights into their habits and lifestyles.
During 2022’s manta ray season, The Manta Trust – whose researchers have run The Maldivian Manta Ray Project (MMRP) at Landaa Giraavaru since 2005 – estimated 6,083 manta ray sightings in the waters around the Resort.
At nearby Hanifaru Bay, famed for its mass manta aggregations, an estimated 5,016 sightings were made. Across the archipelago, 176 manta rays were identified for the first time, bringing the total known Maldives reef manta ray population to 5,507 – the largest recorded in the world.
During June 2022, Landaa Giraavaru’s researchers (and guests!) were also lucky enough to encounter more than 60 manta rays on the Resort’s House Reef. For the first time ever, the mantas were observed engaging in cyclone feeding – a rotating feeding circle resembling a cyclone – within a stone’s throw of the Resort’s Arrival Jetty.
“It was so special to show guests cyclone-feeding mantas directly from the beach,” recalls Ellie Strike, MMRP Project Manager at Landaa Giraavaru. “It goes to show, you don’t always need to visit Hanifaru Bay for manta encounters – sometimes they come to you!”
With wingspans of up to 4.5 metres (15 feet), the largest brain-to-size ratio of any cold-blooded fish, and a cognitive function on a par with dolphins, primates and elephants, reef mantas are some of the most impressive creatures in the ocean.
The importance of facilitating connections to mantas to understand their vital place in our ecosystems has sadly only increased this past year, with giant manta rays – the close cousin of the reef manta – being uplisted in December 2021 to “endangered” on the International Union for the Conservation of Nature Red List. The reef manta ray remains listed as “vulnerable.”
“When a guest meets these intelligent and curious animals in their natural habitat, something truly magical happens,” continues Ellie. “Awed by nature, they quickly come to realise just how crucial it is to take care of our oceans to protect creatures like mantas. For us as researchers and educators, that’s what our work is all about.”
And it’s not just the mantas that are worth getting wet for at Four Seasons Landaa Giraavaru: 2022’s manta season also saw a record 27 whale shark sightings in local waters. The largest of any fish alive today, unthreatening whale sharks also seek to exploit the plankton-rich waters of Baa Atoll – in apparently increasing numbers.
Opportunities for Magical Manta Moments
Guests have various options to interact with mantas during their stay at Landaa Giraavaru. The Resort’s Manta-on-Call service supplies a “manta phone” that rings when mantas are sighted nearby, before a waiting speedboat whisks them away for an unforgettable open water experience. And with manta rays swimming to the surface to feed, the phenomenon is best experienced while snorkelling, making it accessible to anyone able to swim.
Guests can also book private manta-spotting cruises, while the Resort’s new Trainee Manta Biologist program offers environmentally minded 13 to 18-year-olds teens a focused one-to-one deep dive into what it takes to be a Manta Biologist: from photo identification to helping monitor size, behaviour and even pregnancy.
Research driven by the MMRP since its inception in 2005 has been directly responsible for protecting mantas and their critical habitats both within the Maldives and across the world. Some of this research allows the MMRP to determine the most likely mass aggregation dates for mantas around Landaa Giraavaru. 2023’s hot dates are:
- May 17–21
- June 2–6
- June 16–20
- July 1–05
- July 15–19
- July 30 – August 3
- August 14–18
- August 29 – September 2
- September 13–17
- September 27 – October 1
- October 12–16
- October 27–31
- November 11–15
- November 25–29
Note: Manta ray sightings are subject to weather conditions and the temperament of the animals on the day.

Sun Siyam Vilu Reef introduces guest-led coral restoration initiative
Surrounded by one of the Maldives’ most vibrant house reefs, Sun Siyam Vilu Reef, is inviting guests to leave behind more than memories. This World Nature Conservation Day (28th July 2026), the boutique island retreat officially launched its signature ‘Adopt-a-Coral’ initiative, giving travellers the opportunity to play an active role in restoring one of nature’s most precious underwater sanctuaries.

Driven by Sun Siyam Resorts’ overarching sustainability program, Sun Siyam Cares, this initiative provides a hands-on opportunity to safeguard the fragile aquatic landscapes of the South Nilandhe Atoll. Guests become active participants in the restoration process, carefully attaching live coral fragments onto specially designed nursery frames under the guidance of the resort’s marine experts. These structures are then carefully placed in nursery zones across the lagoon to flourish and rebuild vital habitats.

To commemorate the launch, guests enjoyed an interactive morning event featuring bespoke refreshments and a symbolic frame planting ceremony. Long after returning home, guests continue receiving personalised updates, allowing them to witness the growth of the very coral they helped restore, creating a lasting connection with the island and its surrounding waters.

“Our reef is the heart of our island, and protecting it is a responsibility we proudly share with every guest who visits us,” said Masdhooq Saeed, Cluster General Manager. “By giving our guests the opportunity to plant coral, we offer them a meaningful way to leave our sanctuary even better than when they arrived. It is a genuine privilege to empower our visitors to play a direct role in building a more resilient ecosystem while forging a lifelong bond with the Maldives.”
The Adopt-a-Coral initiative forms a key part of Sun Siyam Vilu Reef’s long-term sustainability vision, seamlessly combining luxury island hospitality with meaningful conservation efforts, guest participation, and community engagement. The resort’s spectacular house reef is home to an extraordinary diversity of coral formations, tropical fish, turtles, and countless other species, making its protection essential for future generations.

Fushifaru Maldives offers access to Lhaviyani’s manta ray hotspot
One of the Maldives’ most anticipated marine spectacles has arrived – manta ray season is returning to Lhaviyani Atoll. As plankton-rich waters attract these gentle giants, the atoll transforms into a haven for unforgettable underwater encounters. Graceful, curious and inspiring, manta rays can often be spotted gliding effortlessly through the turquoise waters, creating magical moments for both snorkelers and divers.
Whether you’re taking your first plunge beneath the surface or you’re a seasoned ocean explorer, there’s nothing quite like the thrill of swimming alongside these incredible creatures in their natural habitat. Think vibrant coral reefs, abundant marine life and crystal-clear lagoons. Manta ray season offers an unforgettable experience that captures the true wonder of the Maldives.
One of Lhaviyani Atoll’s most renowned manta ray sites is Fushifaru Thila, located just three minutes by boat from Fushifaru Maldives. This protected dive site is home to a natural manta cleaning station, where cleaner wrasse and other small reef fish remove parasites and dead skin from the mantas. Watching these gentle giants gracefully circle the cleaning station as they pause for their underwater “spa treatment” is a truly remarkable sight and one of the highlights of diving in the Maldives.

Manta Trust turns holiday photos into conservation science in Maldives
Whether you’re snorkelling at Hanifaru Bay, diving next to a cleaning station, or photographing a manta ray from a liveaboard, your holiday memories could help protect one of the world’s most iconic marine animals.
The Manta Trust and its flagship affiliate project, the Maldives Manta Conservation Programme (MMCP), are inviting divers, snorkellers, underwater photographers, resorts and liveaboards across the Maldives to become citizen scientists through MantaBase – a global platform that transforms everyday manta ray encounters into valuable scientific data.
For more than two decades, the MMCP has built one of the world’s most comprehensive manta ray photo-identification databases. With more than 100,000 photographed sightings and over 7,000 individually identified manta rays, the Maldives database has become one of the most important long-term marine wildlife datasets anywhere on Earth.

Now, that remarkable resource is available through MantaBase, allowing anyone visiting the Maldives to contribute directly to ongoing conservation research.
Every manta ray has a unique pattern of spots on its belly – much like a human fingerprint. By uploading a photograph of this pattern, MantaBase’s AI-powered identification system, IDtheManta, can recognise individual animals, revealing whether they have been seen before and adding another chapter to their life story.
Each submission helps researchers better understand where manta rays travel, how populations change over time, which habitats they rely upon, and how they respond to growing environmental pressures.
“Every photograph tells us something new,” says Dr Guy Stevens, CEO and Co-Founder of the Manta Trust. “The Maldives has become one of the most important places in the world for manta ray research because thousands of divers, guides, photographers and resorts have shared their sightings over many years. MantaBase allows anyone to become part of that conservation story.”
“MantaBase is more than a database – it’s a community of ocean enthusiasts whose sightings, memberships and support are helping safeguard manta and devil rays for generations to come.”

The MMCP has spent twenty years working alongside resorts, dive centres, liveaboards and local communities to study manta rays throughout the archipelago. Their long-term research has identified key aggregation sites, improved understanding of manta behaviour and migration, and helped inform the protection of some of the Maldives’ most important marine habitats.
MantaBase now makes it easier than ever for that collaboration to continue.
Divers and snorkellers can create a free MantaBase account to upload sightings, discover the identities of the manta rays they’ve encountered, and build a personal digital logbook of their wildlife experiences. For those wanting to dive deeper into the lives of the manta rays they meet, Premium Membership unlocks additional tools and insights while directly supporting the Manta Trust’s global research, technology and conservation work.
For dive centres, resorts and liveaboards, dedicated Operator Accounts provide an opportunity to showcase their conservation contributions while engaging guests in meaningful citizen science. Operators can track sightings linked to their organisation, celebrate their impact, receive official recognition through the MantaBase support programme, and demonstrate their commitment to protecting the species that make the Maldives one of the world’s premier manta ray destinations.

Every MantaBase membership helps fund the continued development of the platform and supports the Manta Trust’s work to research and protect manta and devil rays around the world. By becoming a Premium Member or joining as an Operator, users not only gain access to exclusive features, but also help power the science and conservation initiatives that make MantaBase possible.
The launch represents another milestone towards creating the world’s largest connected database for manta and devil rays, bringing together regional conservation projects from across the globe to support international research and protection.
Whether you’re visiting the Maldives for your very first manta encounter or have spent decades diving these waters, every sighting helps strengthen our understanding of these extraordinary animals. Whether you choose a free or Premium account, every photograph you submit helps build a better future for manta and devil rays.
Together, one photograph at a time, help secure a future for manta rays.
