Reserve rules and boat access make a local guide or operator the practical option.
Ilet Requin is a shallow boat-access site off Cul-de-sac near Anse Marcel, centered on a rocky outcrop with sand and turtle grass around it. Small canyon-like cuts and a simple layout make it a solid choice for training or relaxed discovery dives when the sea is settled, with a mixed reef profile rather than a dramatic wall.
