La Passe St. Jacques is a classic Le Morne drift that runs along a shallow start before carrying divers past pinnacles, coral, and open current. It suits experienced scuba divers who want a committed route with strong flow and a real sense of motion rather than a relaxed reef circuit. The site is known for sharks, rays, barracudas, tuna, and giant lobsters, so the dive rewards steady buoyancy and good team discipline. Plan it as a current-led boat dive with an operator brief and a firm exit plan.
