Plunge into Mayotte's legendary outer reef passes for world-class drift diving with manta rays, whale sharks (seasonal), and vast schools of hammerheads — a dive destination that serious underwater explorers rank among the Indian Ocean's finest.
What to expect
Gear up on the private jetty in Mamoudzou and head out to the outer passes — Passe en S or Passe Bandraboua — where tidal surges funnel nutrient-rich water and concentrate pelagic life in breathtaking density. Drift effortlessly past eagle rays, barracuda, and Napoleon wrasse, with the ever-present chance of a manta ray glide-by overhead. Surface intervals are spent at anchor in turquoise shallows with fresh fruit; the second dive targets coral pinnacles alive with macro life. Back on board, the dive master briefs the sightings log over cold drinks.
Good to know
PADI Open Water certification required; dive master in-water with every group. Book minimum 48 hours ahead as spaces fill quickly. Confirm morning departure (08:00) against all-aboard time — a two-tank day tour typically concludes by 13:30.
