Dive Site: Brissare Rocks (Mahé)

About Brissare Rocks (Mahé)

Brissare Rocks, located just north of Mahé, is a renowned dive site in Seychelles, widely considered one of Mahé's top five. These two rocky inlets are easily accessible; it's only a 15-minute boat ride from Beau Vallon, a popular beach on Mahé. The site is frequently paired with Dragon's Teeth for a two-tank dive due to their close proximity. Underwater, Brissare Rocks features the distinctive granite rock formations found throughout the Inner Islands, creating caves, overhangs, and swim-throughs that provide diverse habitats. This unique topography contributes to the site's rich biodiversity. Visibility at Brissare Rocks typically ranges from 15 to 30 meters, and depths can reach around 20 meters. Divers at Brissare Rocks encounter an abundance of marine life. Massive schools of Bengal snapper often surround divers, while moray eels peek from granite crevices and batfish glide by. Trumpetfish, wrasses, jacks, banded butterflyfish, and various tangs are common sights. The site is particularly known for attracting larger pelagic species, including sharks, rays (such as whitetip reef sharks and eagle rays), and barracudas, thanks to the currents that sweep through the area. Other frequently spotted creatures include groupers, triggerfish, lobsters, angelfish, glassfish, and several species of starfish and corals. While Brissare Rocks is celebrated for its vibrant marine ecosystem, it can experience strong currents, especially attracting the pelagic species it's known for. Divers should be prepared for varying current conditions, which can make for an exciting drift dive, though good buoyancy control is advisable. Despite the potential for strong currents, the rich corals, sponges, and teeming sealife make it an incredibly rewarding dive experience suitable for certified divers comfortable with current.

Conditions & Currents

Brissare Rocks is known for its potentially strong and unpredictable currents, which are a primary factor in attracting the large pelagic species that frequent the site. These currents can change direction rapidly, necessitating excellent buoyancy control and awareness from divers. Entry is typically a live drop to manage the conditions effectively, with the dive often evolving into a drift. Divers should be prepared for varying levels of surge, particularly around the rocky inlets. Visibility is generally good, ranging from 15 to 30 meters, though strong currents can occasionally stir up particulate matter. There are no notable thermoclines within typical recreational dive limits. This dynamic environment rewards experienced divers with thrilling encounters but requires careful dive planning and adherence to safety protocols.

Dive profile & how the dive runs

Dives at Brissare Rocks typically begin with a live drop from the boat onto the main granite formations, often around 10-15 meters, especially if currents are strong. From here, divers can explore the intricate network of archways, swim-throughs, and crevices that characterize the site's unique granite topography. The dive usually progresses to depths around 20-25 meters, where schools of reef fish are abundant and larger pelagics patrol. Depending on current direction and strength, the dive may be a drift along one side of the rocks, or divers may circumnavigate a specific pinnacle. The deepest areas can reach 40 meters, but the richest biodiversity is typically found in shallower zones. Turn point is determined by air consumption and no-decompression limits. The safety stop is generally conducted in the blue at 5 meters, with careful attention to surface support for pickup due to potential currents.

Underwater photography

Brissare Rocks offers excellent wide-angle photography opportunities, especially to capture its unique granite formations and the potential for large pelagic encounters. A wide-angle or fisheye lens is ideal for showcasing the dramatic underwater landscape and schooling fish. For smaller subjects like moray eels tucked into crevices, a macro lens or a mid-range zoom can be effective, though the primary focus here is on the grander scale. Natural light is often sufficient in shallower areas given good visibility, but strobes are highly recommended to bring out the vibrant colors of corals and fish, especially in deeper sections or when shooting against the sun. Maintain impeccable buoyancy to avoid disturbing sediments and to navigate the currents smoothly. When approaching larger marine life, observe from a respectful distance to minimize disturbance.

Getting there & logistics

Access to Brissare Rocks typically originates from Mahé, the largest island in Seychelles, which hosts the Seychelles International Airport (SEZ). Divers usually fly into SEZ, with direct connections available from major hubs like Dubai, Doha, and European cities. Day trips to Brissare Rocks are commonly arranged from dive centers on Mahé, particularly around Beau Vallon. For more extensive diving, Brissare Rocks is a frequent inclusion in Inner Islands liveaboard itineraries departing from Victoria Harbour on Mahé. These liveaboards often combine multiple Mahé-area sites over 7- to 10-day trips, sometimes extending to nearby islands like Praslin and La Digue. No special permits beyond standard dive tour arrangements are typically required, but confirming park fees with your operator is advisable.

Safety & environment

Diving at Brissare Rocks requires careful attention to safety due to its exposed location and potential for strong, unpredictable currents. All divers should have valid dive insurance that covers emergency evacuations and recompression treatments. The nearest recompression chamber is located on Mahé. In case of an emergency, evacuation would typically involve boat transfer to Mahé, followed by land transport to medical facilities, which can be time-consuming. Divers must maintain excellent buoyancy control and stay close to their buddy and group, especially during drift dives. Always follow your dive guide's instructions regarding entry points, exit procedures, and current management. Conduct rules include avoiding contact with marine life and refraining from feeding fish, to preserve the delicate ecosystem.
