Visitor testimonials

“A faire ! Personnel top, sympa et compétent. A 9h45 nous étions 10 sur le bateau. On nous explique les fonds marins, pause baignade et c'est reparti. Idéal pour les enfants. On a même vu une tortue ! Privilégier le 1e créneau horaire pour éviter de voir plus de plongeurs que de poissons.”

“Superbe, on voyait tous les poissons et on se voyait sous l’eau pendant le moment de plongé autorisé (certains étaient dans le bateau pour voir le dessous de l’eau, pendant que d’autres étaient en train de plonger). Bref, super activité familiale :)”

“Une très belle expérience depuis Malendure pour cette sortie en bateau en coque de verre pour pouvoir admirer les fonds marins autour de l'îlet Pigeon (connue comme la réserve Cousteau). 1h15 aller retour et baignade sur place. Masques et tubas conseillers tellement c'est beau. On descend en groupe dans la cale et on admire ce monde sous-marin magique. Le capitaine est présent et explique ce que nous voyons et est toujours à disposition. Je vous recommande cette sortie.”
