Scuba diving at Shark Bank and Brissare Rocks
Scuba diving at Shark Bank and Brissare Rocks offers some of Mahé's most dramatic seascapes — vertical walls, isolated bommies and the chance to encounter reef sharks and large pelagics. Both sites are boat-access only, typically combined as a two-dive trip from Mahé. Visibility is usually good (10–30 m) and dives range from shallow coral gardens to deeper walls and pinnacles.

Approximately 4–6 hours total for a two-dive trip (includes surface interval and boat transit). Single dives or private charters vary; full-day trips with additional sites can run 6–8 hours.
Best Time to Visit
April to November (generally clearer, calmer seas and better visibility). Diving is possible year-round, but December–March can be windier and rougher due to the northwest monsoon.

Itinerary
Pick-up and check-in
Operator picks divers up from hotels or from the dive centre. Sign waivers, confirm dive experience and brief itinerary.
Pre-dive briefing & gear check
Detailed site briefing, buddy checks, weights and equipment setup. Discuss currents, entry/exit procedures and emergency plan.
Boat transfer to first site
Boat ride depending on launch point: typically 20–50 minutes. Light refreshments provided on many trips.
First dive (45–60 minutes)
Explore pinnacles/walls; deeper maximum depths possible — monitor air and no-decompression limits.
Surface interval
Snacks, brief rest and optional briefing for second dive; re-hydrate and prepare for next descent.
Second dive (45–60 minutes)
Often at the other site (Shark Bank or Brissare Rocks). Keep an eye on currents; remember safety stop procedures.
Return to port and debrief
Unload gear, log dives, operator may offer photos and discuss sightings. Transport back to hotels where provided.
Safety Requirements
Minimum PADI/SSI Open Water or equivalent for sheltered, shallow sections; Advanced Open Water recommended for deeper, current-affected sites.
A good recent dive history (minimum number of dives in the past year) may be requested — operators commonly require a logged dive within last 6–12 months or a refresher.
Medical fitness to dive required — complete operator medical form. Consult a doctor if you have any chronic or recent illnesses.
No solo diving — use buddy/team and follow guide instructions at all times.
Be mindful of currents and depth limits; follow the guide’s plan for entry/exit and navigation around pinnacles.
Use of surface marker buoy (SMB) recommended for certain drift sections; operator may provide or require one.
Tips
Bring your dive certification card and logbook; many operators check certification and recent dive history.
Book in advance during high season (June–September) — space on small boats fills quickly.
If you plan to take photos, bring a wide-angle housing and anti-fog inserts; lighting is helpful for shots near walls and overhangs.
Use reef-safe sunscreen and avoid touching corals — the ecosystems are fragile.
Consider Nitrox if available (for longer bottom times) and if you are certified; check with operator for fills.
Wear a light windproof layer for the boat ride and bring a towel; motion-sickness meds recommended if you’re prone to sea-sickness.
Confirm what’s included (tanks, weights, guide) and what’s extra (equipment rental, park fees, dive insurance).
Choose a reputable, locally recommended dive operator with experienced guides familiar with Shark Bank and Brissare Rocks for safety and best sightings.
