Lovely! Bora Bora! On my bucket list, as is Palau.
I have had the good fortune to live overseas on 5 continents over a 20 yr period before returning home last year. It’s a close tie for me. I think I’d have to say Chongoene in Mozambique, beyond the town of Xai-Xai. The coast of Mozambique is utterly unspoilt, utterly empty, and beautiful. Evenings watching whales making their way southwards, and days wandering completely empty and beautiful heaches. Having said that….there are some island beaches off the east coast of Malaysia, and one or two in Japan that almost take the prize for me..although if forced I’d say Mozambique.
