This list has been made by a long time family friend called François. He has travelled the world many times and has visited every imaginable place, from Belgium to French Polynesia to the Bahamas to Australia … he has done it all. All of these trips were mostly in function of his passion and profession, diving.

For him the following spots are the most beautiful ones ever :

1.                   François’ absolute nr 1 would be Rangiroa (Tahiti) in French Polynesia.

2.             Fernando de Noronha, Brazil (east of Natal). If you dream of swimming with hundreds of dolphins … this is THE place to be. The only thing that could be tricky is the fact that only a certain amount of tourists per year are allowed here.
