“Perfect snorkelling activity without needing to be up early or out on a boat for 7+ hours. This got all the major sites of Koh Tao bays with good time to see things. If I could have asked for anything, it would have been a little longer at each stop, but I think that’s the nature of the tour to give a glimpse of each. I would do this tour day one of Koh Tao, give you a glimpse of coves/beaches you may want to return to during your stay.”

“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. Il n'y a pas d'étui de fourni pour les cellulaires. Cest mieux dapporter une bouteille d'eau personnelle. Sensation de picotement lorsquon est dans l'eau mais qui disparait lorsqu'on se rince a leau fraiche. Repas: riz blanc, poulet bouilli, 3 morceaux de légumes, aucune épice. La mer étant agitée nous…”
