Dive Site: Amirantes Atoll

About Amirantes Atoll

The Amirantes Atoll, part of Seychelles' Outer Islands, stands as a remote diving frontier, renowned for its pristine marine environment and exclusive access. This region offers a unique blend of shallow, light-filled coral gardens and dynamic drop-offs, making it a diverse underwater landscape suitable for various dive interests. Its position on a shallow plateau, interspersed with deeper channels and seamounts, creates a habitat rich in biodiversity, attracting both resident reef dwellers and migratory pelagic species. Diving here reveals a vibrant ecosystem where healthy corals thrive, supporting an abundance of reef fish. Beyond the tranquil lagoons, dramatic walls and pinnacles plunge into deep waters, patrolled by various sharks and manta rays. The unique topography around islands like Desroches, with its extensive cave systems and gulleys, further enhances the exploratory appeal of the atoll, presenting an ever-changing environment for divers. The atoll’s relative isolation ensures uncrowded dive sites, offering a sense of discovery on every descent. The calm conditions within the shallow reefs are ideal for macro photography and leisurely exploration, while the strong tidal shifts near lagoon inlets create powerful drift opportunities, often leading to exhilarating encounters with larger marine life. This contrast defines the diving experience, from serene observation to adrenaline-fueled drifts. Access to the Amirantes is typically via liveaboard, which allows for comprehensive exploration of its numerous, often seldom-visited sites. The best conditions, characterized by calm seas and excellent visibility, are found during specific transitional months, optimizing the chances for incredible marine encounters and maximizing dive opportunities across this spectacular, untouched underwater world.

Conditions & Currents

Currents in the Amirantes Atoll can vary significantly, ranging from calm conditions within shallow lagoon flats to powerful, fast-paced drifts, particularly around lagoon inlets and deeper channels. Strong tidal shifts characterize some areas, creating dynamic drift opportunities where divers are carried along by the flow. While exhilarating for pelagic encounters, these strong currents necessitate excellent buoyancy control and active finning to maintain position and avoid contact with the reef. Divers must pay close attention to pre-dive briefings, as entry and exit strategies are often current-dependent, with negative entries sometimes required. Visibility generally remains excellent, frequently exceeding 30 meters, though localized conditions and recent rainfall can cause temporary reductions. Thermoclines are generally not a significant concern, with water temperatures consistently

Dive profile & how the dive runs

Dives in the Amirantes Atoll frequently involve drift diving due to the prevailing currents. The typical profile begins with a negative entry from a Zodiac, allowing divers to quickly descend and establish neutral buoyancy to avoid being swept past the intended site. Once submerged, the dive master will lead the group along a reef wall or over a coral plateau, letting the current carry the divers. Depths often range from 15 to 25 meters, exploring coral formations, caverns, and observing pelagic life in the blue. For instance, a dive might start on a seamount at 18 meters, slowly drifting along a drop-off reaching 30 meters, before ascending gradually to shallower reef sections at 10-12 meters. Turn points are usually dictated by the current or air consumption, with safety stops performed while drifting in the blue or ascending along a protected area if available. The support vessel tracks the divers from the surface, ensuring a pick-up at the end of the drift.

Underwater photography

Underwater photography in the Amirantes Atoll offers diverse opportunities, from wide-angle reefscapes to macro subjects. For capturing the expansive coral gardens, schooling fish, and pelagic encounters, a wide-angle lens is essential. Consider a fisheye for dramatic close-focus wide-angle shots, especially around the vibrant pinnacles and deep walls. For macro enthusiasts, the calm conditions in the shallow lagoon flats are ideal for finding nudibranchs, hawkfish, and other small critters; a 60mm or 100mm macro lens will be beneficial. Dual strobes are highly recommended for illuminating corals and bringing out the true colors, particularly at deeper depths or when shooting against the sun. Given the potential for strong currents during drift dives, excellent buoyancy control is paramount to avoid disturbing delicate marine life and to maintain stable shots. Always respect marine life by maintaining a respectful distance and avoiding contact.

Getting there & logistics

Access to the Amirantes Atoll is primarily via liveaboard vessels departing from Mahé, the main island of Seychelles. Seychelles International Airport (SEZ) on Mahé is the international gateway, served by airlines such as Air Seychelles, Emirates, and Ethiopian Airlines. Trip durations typically range from 7 to 10 days, with itineraries often combining the Amirantes with other Outer Islands such as Alphonse Atoll or Desroches. While there are no specific local fees mentioned for the Amirantes alone, marine park fees are generally applicable in Seychelles, and these are usually incorporated into liveaboard package costs. It is crucial to arrange international flights to Mahé and then domestic transfers or direct liveaboard connections. Given the remote nature of the atoll, liveaboards offer the most practical and comprehensive way to explore its diverse dive sites.

Safety & environment

Diving in the remote Amirantes Atoll demands meticulous adherence to safety protocols. The nearest recompression chamber is located on Mahé, which means evacuation can be time-consuming and complex in an emergency. Divers must ensure they have comprehensive dive insurance that covers emergency medical treatment and evacuation, as rescue operations in such remote areas can be extremely costly. During drift dives, which are common here, close attention to the dive briefing is critical, covering entry procedures, descent timing, and surface signaling. Divers should always carry a delayed surface marker buoy (DSMB) and know how to deploy it, as well as an audible signaling device. Staying with your buddy and maintaining excellent buoyancy control are paramount to prevent separation and avoid accidental contact with the reef or strong currents. Given the potential for powerful currents, divers should be comfortable with these conditions; those with limited drift diving experience may find some sites challenging.
