Don't miss this ecologically conscious marine and research centre dedicated to sea turtles, about 2km north of St-Leu. It features exhibits, interactive displays and big tanks where you can get a close-up look at the five different varieties of turtle found in the waters around Réunion, especially the green turtle (Chelonia mydas) . Kids love the place but adults will also be blown away by this well-organised venture. Guided tours are available.
