Unique in the Antilles, this aquarium in the marina near Pointe-à-Pitre is a good place to spend an hour. Its motto is: "Visit the sea." The well-planned facility has an assortment of tropical fish, crabs, lobsters, moray eels, coffer fish, and some live coral. It's also a turtle rescue center, and the shark tank is spectacular. A restaurant serves kid-friendly fare, snacks, salads, pastas, etc. A small shop stocks marine toys and souvenirs.
The aquarium also offers a half-day ecotour, in which small boats travel through the mangroves, reefs, and a lagoon, with a biologist guide and a diving instructor on board. Leaving daily at 8:30 am and 1 pm, the tours are €59. Snorkeling gear is included, and kids are more than welcome. A full-day ecotour includes lunch and a visit to the aquarium (€95).
