Zoe:
I guess you have good flight connections from Europe, Air France?
Air France has weekly flights from Paris indeed, but I fly Kenya Airways Amsterdam - Nairobi - Bangui because its schedule connects with the charter flight on Sunday from Bangui to Sangha NP.
Zoe:
Anyway so I take it no plan to visit St Floris?
I don't believe that's accessible at all at the moment and it lies in a much more dangerous area in the border region with Tchad.
