“Activity was amazing. We loved every stop, and we saw so much wildlife- turtles, sharks, starfish, loads of colorful fish and coral. The go pro was also an added bonus- we were impressed by all the photos/videos taken and shared with us day of. The only downfall we had were the snorkeling masks. Ours kept fogging up and we had to adjust constantly. Overall, we were very impressed and would definitely book again!”

“Les plus: guide expérimenté, connaît bien les lieux, tres gentil. Une personne avait le mal de mer et a reçu un traitement a bord rapidement. Le capitaine connaît également bien les lieux. Beaucoup d'espèces de poissons dont des poissons ange et des poissons peroquets, quelques tortues, flore abondante mais terne. Les moins: les palmes ne sont pas incluses dans le prix.
