Aldabra (but also Stone Town, Kilwa Kisiwani and maybe Vallée du Mai)
Here the details:
*
Ponant is doing this (among other routes all over the world that also touch remote WHSs)
* The "simplest" cabin (still total shiny luxury for what I understand) starts
from 6220 * Next dates are in
February and March 2024, then to be announced
*
13 days, 12 nights onboard
* The itinerary starts from
Stone Town, then heads to Pemba and its Misali islet (a small jewel, I can tell from experience, seemingly with a slight WHS potential...) and after that arrives at
Kilwa (with visit); then goes through Assumption Island and stops from some time at
Aldabra; then Astove and finally to the Seychelles, where it does not seem to stop at Praslin for the
Vallée du Mai (but who knows), though it passes at La Digue and finally lands at Victoria.
* Remember that you have to bring (also) formal clothes and a special dress for the Captain's night...
So 3 WHSs on a string with an easy addition (Vallée du Mai), among which the legendary Aldabra. I was myself recently considering this tour as it seems very well done, or at least presented. Dates seem good to plan for it, and hey, I for sure need a revisit to Stone Town!
