Merci Marvyn pour cette excursion au top ! La météo était capricieuse mais n'a enlevé en rien la beauté des paysages ! On retiendra le "pa ni pwoblem", l'apéro à l'îlet de la biche les pieds dans l'eau au milieu des poissons (un régal pour les yeux et pour l'estomac) sans oublier ton ti'punch, ta bonne humeur, tes anecdotes et ta simplicité ! Je vous le recommande comme guide, vous êtes sûr de passer un excellent moment ! Mési ;)

Grand Cul-de-Sac Marin Immersion – Mangroves, Islets & Snorkelling – Full Day
The experience
Set off to explore the Grand Cul-de-Sac Marin with Marvyn: mangroves, unspoilt islets, an underwater shipwreck, snorkelling and a Creole lunch with your feet in the water – an immersive day out in Guadeloupe.
Meet at 8.15 am at the jetty by the harbour master’s office at Gosier Marina, where Marvyn will welcome you and go through the itinerary and safety instructions. The boat then sets course for the Rivière Salée: as you glide through the mangroves, your guide will explain the vital role of the mangroves and help you spot birds and crustaceans. You’ll board at 8.30 am at pontoon 7 at Gosier Marina, where Marvyn will welcome you and go over the programme and safety instructions. The boat then sets course for the Rivière Salée: as you glide between the mangroves, your guide will explain the vital role of the mangrove forest and help you spot birds and crustaceans. At around 9.30 am, you’ll reach the shores of Caret Islet. Its calm, shallow waters are ideal for a peaceful swim: enjoy the natural setting, breathe in the sea air and relax as you gaze out over the turquoise sea. At 10.30 am, head for the half-submerged shipwreck: grab your mask and snorkel for a fascinating snorkelling experience, amidst schools of tropical fish and the reefs that have formed around the hull. At 11.30 am, set off for Îlet de la Biche to enjoy an aperitif made with local produce, followed by a Creole lunch with your feet in the water, looking out over the azure horizon. Refreshed, you’ll continue at 2 pm with a stop to explore the “starfish spot”, then enjoy one last spot of free snorkelling. At the end of the day, the return journey to Gosier Marina is accompanied by music, adding a convivial and festive touch to this immersive experience.
