on the Seychelles, including speaking with people who have been. I never made it, but we blew it off on our honeymoon to spend more time in Botswana with the idea that we would get there someday. Information isn't easy to come by, but I recently read a very good article in a periodical, a journey to the southeastern (or western) islands, very remote, only accessable (unless you have your own ocean going boat) a few months of the year. I believe the article was in Skin Diver, but it may have been National Geographic.
Quite expensive. But, take some time to do the research as it is one of the most intersting travel destinations I have researched (I read a ton of off the beaten path travel information). The islands were formed when two continental plates split, and like the Galapagos, unique species literally evolved there. (Like the Galapagos they too are famous for their tortoises).
I spend a fair amount of time in Quogue, LI if you are ever in the neighborhood, I may have some information I can dig up. I gave most of my Africa information away recently to a non-diver and may have saved some Seychelles stuff.
The travel agent that specialized in that area was a guy named Phil Encarta, or Phil Something or other that sounds like that. He has a newletter and if memory serves me correctly he books from Africa. (Flights into the Seychelles are few and far between, I think there were two operators in Sept 98 when we got married... Air Seychelles that left from Nairobi and "Kenya Crash" that had flights from Nairobi, Dar Es Salaam and one other place... Mombasa maybe).
If you are looking at that type of thing, look at the Maldives too. There are some easier to get (yet still not really visitted) areas there too. Again, I'm speaking from research, not experience.
