After grabbing lunch on the ultra-local Plage de la Datcha on the south of Grande-Terre, hop on an afternoon boat shuttle from the beach to nearby Îlet du Gosier. You can spot the islet from shore—and if you’re fit, you can even kayak or swim over. With a wraparound white-sand beach, shallow waters for snorkeling, and the rustic Ti’ Robinson bar for rhum cocktails and Creole dishes, it’s the perfect day trip from somewhere like Pointe-a-Pitre.
