Aldabra Atoll,Seychelles
UNESCO World Heritage Site and one of the world's largest raised coral atolls, Aldabra Atoll is globally important for biodiversity and conservation. It hosts the largest remaining population of the Aldabra giant tortoise, extensive near-pristine coral reefs, vast seagrass beds, and huge seabird colonies. The atoll's isolation has preserved many endemic species and unique ecosystems, making it a living laboratory for evolutionary and conservation science.
Historic Anecdotes
Local and maritime lore highlight Aldabra's remoteness and mystery. Sailors' tales once spoke of the island's 'armada' of giant tortoises and of deserted shipwrecks around the reefs. Scientific legend notes Aldabra as a celebrated example in studies of island biogeography and conservation, often cited in accounts of successful long-term protection driven by limited human interference.
Places to visit
- Aldabra Lagoon – a vast, shallow central lagoon encircled by coral and sandbanks
- Giant tortoise populations – free-roaming Aldabra giant tortoises on the islands
- Seabird colonies – large nesting grounds for terns, noddies, and frigatebirds
- Aldabra Rail – the endemic flightless bird unique to the atoll
- Pristine coral reefs and marine life – snorkeling and diving habitats (access controlled)
Unique Aspects
- Raised coral atoll structure with multiple islands and narrow channels
- High level of endemism among reptiles, invertebrates and plants
- Relatively untouched ecosystems due to restricted access and active conservation
- Important nesting beaches for sea turtles and significant seagrass beds supporting marine fauna
Things to do
- Guided eco-expeditions (by permit) led by conservation or scientific teams
- Wildlife watching – observe giant tortoises, seabirds and unique shore fauna
- Snorkeling and limited diving in designated areas with strict controls
- Photography and nature study – excellent opportunities for birding and macro photography
- Research visits – scientific fieldwork and conservation volunteer programs (by arrangement)
Festivals & Events
- There are no local festivals on Aldabra due to its uninhabited, conservation-focused status. Occasional scientific symposia or conservation events may be organized by the Seychelles Islands Foundation or partner institutions off-site.
Best Time to Visit
The drier, cooler months (roughly May to October) are generally best for sea conditions and wildlife viewing. The wet season (November to April) brings warmer weather, heavier rains and occasional rough seas.
Weather Conditions
Tropical marine climate: temperatures usually range between 24–30°C (75–86°F) year-round. Expect humidity, with wetter conditions and occasional storms/cyclones possible during the northwest monsoon/wet season.
Entry Fees & Permits
Access is strictly controlled. Visitors must obtain permits and pay any landing or research fees set by the Seychelles Islands Foundation (SIF) in advance. There are no public facilities or visitor 'opening hours'—visits are arranged as part of authorized expeditions or approved research trips. Apply for permits well in advance.
Accessibility
Aldabra is remote and not served by regular commercial transport. Access is typically by authorised scientific or eco-tour vessel from Mahé or other islands; occasional charters and specialist expedition cruises include Aldabra. Permission from SIF is required before travel. There are no tourist lodges on the atoll—only limited field accommodation for permitted personnel.
Recommended Duration
Plan for at least 3–7 days on an authorised expedition to allow for sea travel time, permits, and meaningful wildlife viewing. Researchers and volunteers will require longer stays depending on project needs.
Clothing & Gear Tips
Bring lightweight, breathable clothing, a wide-brim hat, UV-protective layers, sturdy walking shoes, reef-safe sunscreen, insect repellent, binoculars, waterproof bags, and seasickness medication. All gear must be clean and free of seeds/soil to comply with biosecurity rules.
Local Food & Souvenirs
There are no shops or commercial souvenirs on Aldabra; visitors must bring provisions as required by the expedition operator. Do not collect any natural items (shells, coral, plants, or animals) — removal is illegal. If you wish to support local communities, purchase ethically sourced Seychelles products (vanilla, local crafts) back on Mahé.
