About the activity
As the sun dips below the horizon in Martinique, the landscapes of Les Anses-d'Arlet are transformed: a warm orange glow reflects off the ocean, a peaceful calm settles in, and new species begin to stir. Beneath the surface, the same transformation takes place, turning the turquoise underwater world familiar to snorkelling enthusiasts into a singular realm teeming with bioluminescent micro-organisms, lobsters, slipper lobsters, and octopuses. Meanwhile, the warm Caribbean waters — averaging 27 to 30 degrees year-round — maintain a comfortable temperature that makes night snorkelling at Les Anses-d'Arlet an irresistible prospect!
A truly unique experience led by qualified diving instructors who specialise in Martinique's marine life, this night snorkelling excursion is open to beginners and experienced snorkellers alike. There's no need to be able to swim, as buoyancy aids are provided, allowing you to float comfortably at the surface and take in the wonders of the nocturnal underwater world at your own pace. As the excursion sets off at sunset, you won't be plunged into complete darkness — quite the opposite, in fact, as you'll be able to enjoy the gradual shift in atmosphere as night slowly falls.
For your safety, your instructor will accompany you throughout the experience and share their knowledge of the species you encounter. Thanks to the small group size, the excursion lends itself to conversation and is conducted with full respect for the marine environment. Over 1 hour 15 minutes of night snorkelling at Les Anses-d'Arlet, your instructor will reveal all the magic of the underwater world after dark: the phenomenon of bioluminescence, species whose behaviour changes at nightfall, and those that only become visible once the sun has set.
Open to anyone aged 5 and above, this is a wonderful opportunity to share an unforgettable moment with family or friends. Whether you've snorkelled before or not, the beauty of this night snorkelling experience in Martinique is guaranteed to leave you speechless. Les Anses-d'Arlet await — book your spot without delay!
