Swim with starfish and pelicans in Guadeloupe’s wild mangroves

You’ll get fruit juice or planter punch served right on board—or sometimes standing waist-deep in clear water before heading back ashore.

What’s the experience like?

You’re just there—bare feet on the boat deck, sun already warming your shoulders, and the water in Grand Cul-de-Sac Marin is that impossible blue-green. Our captain, Nico, grinned as he handed out masks and fins (I always struggle with the straps), then pointed out the first stop: a sandbar so white it almost hurt my eyes. “It’s where the terns nest,” he said quietly, like we shouldn’t disturb them. The air was salty-sweet and I caught a whiff of sunscreen from someone behind me. It all felt a little unreal.

We drifted past Bird Island—frigates wheeling overhead, brown pelicans looking half-asleep on the branches. Nico had binoculars for us to try but honestly I just watched with my own eyes; everything felt close enough to touch anyway. He told us how these islets formed after storms (I didn’t catch every word—my French is rough), but you could hear in his voice he cared about this place. There was a moment when we all went quiet except for the slap of water against the hull.

Swimming in the mangroves was… strange at first. The roots twist everywhere and tiny fish dart around your ankles—Nico called it a “nursery.” I kept thinking about how old these trees must be. There was juice and planter punch after (with our feet still dangling in the lagoon), and someone tried to say “merci” in Creole—Nico laughed so hard he nearly dropped his cup. I still think about that light through the leaves, greenish-gold, kind of peaceful and wild at once.
