Sec Jaune is a boat-accessed Réunion reef with arches.
Sec Jaune is a boat-accessed Réunion reef with arches.
Sec Jaune is a Réunion reef plateau between Saint-Leu and Etang-Salé that is best explored slowly when the sea is calm enough to read the structure. The site mixes arches, coral heads, and deeper cave-like sections, so the dive works well as a patient route with frequent pauses to scan for schooling fish and camouflaged critters. It is a boat-accessed site that rewards steady buoyancy and good timing more than speed.
