Aldabra lies outside the Indian Ocean’s cyclone belt, so there’s no true off season, but conditions are calmest during the April and October shoulder months, when winds ease to 5-10 knots and visibility often exceeds 30 metres. The steady southeast trade winds from May to September suit more experienced sailors, while the northwest monsoon from November to March brings brief afternoon showers and warmer, more humid air.
There’s no airstrip on Aldabra itself, so access is by sea only, typically a three to four day passage by private yacht from Mahé, more than 700 kilometres away. An alternative is a charter flight to nearby Assumption Island followed by a boat transfer for a single-day visit. Every visit, however you arrive, requires advance permission from the Seychelles Islands Foundation, which manages the atoll.
Aldabra has no marina or fixed moorings, and the lagoon’s tidal channels run too strong for comfortable overnight anchoring, so yachts typically lie off the reef near the Seychelles Islands Foundation’s research station at La Gigi on Picard Island. From there, tenders carry visitors ashore and through the calmer channels at slack tide, always accompanied by an SIF ranger.
Most itineraries build in at least two to three full days on the atoll itself, enough time to explore Picard, Grande Terre and the lagoon’s channels by tender, on top of the six to eight days of sailing to and from Mahé. Given how remote and weather-dependent the passage is, Aldabra tends to feature as the centrepiece of a longer Seychelles expedition rather than a quick stop.
Yes. Aldabra is a strictly managed nature reserve, and only private yachts, live-aboard dive boats and small expedition vessels that have secured prior permission from the Seychelles Islands Foundation may visit. A staff ranger accompanies every group ashore, visits are limited to designated areas, and the tortoises, birds and reef are otherwise left undisturbed, which is precisely what has kept the atoll so pristine.
