“Great snorkelling opportunities. Got to see baby sharks and turtles. Crew on the boat were really friendly and helpful. I did feel sorry for the turtles - we were told not to swim above the turtles or too close to them, but I felt people swarmed the turtles and got way too close to them, all for a photo! Just be mindful not to get too close!!”

The crew was amazing—so kind and attentive. Chart and his wife were fantastic hosts, and the food she prepared was delicious! A lovely bonus was Koko, their adorable baby dog!

“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.

La mer étant agitée nous…”
