On my list:

2 km south of Tadine, on the side of the road, this natural aquarium looks like a small portion of the lagoon trapped in a coral wall encircled with plants. This shallow pool with its emerald tones – it is forbidden to swim there – communicates with the sea through a siphon. During the cyclonic period, fish and turtles come to find refuge there. Just across the road from the natural aquarium, Wi Dongo is home to a variety of centuries-old endemic mangrove trees.
