Walk along the bottom of the ocean
For non-divers and non-swimmers, the underwater sea walk is a great way of seeing the island’s marine life. Trips leave from the beach at Grand Baie, 15 minutes’ drive around the headland from Calodyne. Small groups get to put on spacemen-type diving helmets, then tread the ocean floor, surrounded by coral gardens and glamorously dressed fish. It’ll feel like you’re walking on the moon.
