Dive Site: St. Pierre

About St. Pierre

St. Pierre Islet is a distinctive granite pinnacle rising from depths of around 25 meters, situated north of Praslin. This site is renowned for its iconic granite formations, which create a captivating underwater landscape of boulders, swim-throughs, and micro-habitats, offering a truly unique diving experience unlike the sand-and-coral atolls found elsewhere. The site works best at slack tide, providing access to its full range of features. Depths at St. Pierre range from 4 to 25 meters, accommodating both entry-level divers and those with more experience. Its eastern side features a notable cave that divers can explore, revealing various reef fish and occasional whitetip reef sharks. The surrounding boulders shelter a rich diversity of marine life, including nurse sharks, hawksbill turtles, and dense schools of snapper. While generally accessible for all experience levels, conditions can vary significantly with tidal phases, making current management an important aspect for intermediate to advanced divers. Visibility typically ranges between 15 to 25 meters during the inter-monsoon windows, offering clear views of the vibrant marine ecosystem. This site provides an ideal opportunity for divers to immerse themselves in the Seychelles' unique granitic underwater environment and observe its resilient marine inhabitants.

Conditions & Currents

Currents at St. Pierre are highly dependent on the tidal phase, making it crucial to time dives for slack tide. When strong currents are running, particularly around the northern face, the site can become challenging, moving divers faster than desired and making it unsuitable for beginners. In such conditions, intermediate to advanced diving skills are required, necessitating careful current management and potentially a surface swim back to the boat. Visibility at St. Pierre typically ranges from 15 to 25 meters, with occasional stronger currents potentially impacting clarity. Water temperatures average between 27-30°C, ensuring comfortable diving conditions despite any current challenges. Due to the variable conditions, divers should always consult with their dive guide for the day's specific current forecast and plan their dive entry and exit accordingly.

Dive profile & how the dive runs

Dives at St. Pierre are typically conducted from a boat, often timed to coincide with slack tide to mitigate strong currents. The dive begins by descending onto the granite pinnacle and its surrounding boulder formations. The initial depth for easy dives can be as shallow as 4 to 12 meters, allowing beginners to comfortably explore the upper reef. More experienced divers can venture deeper, following the granite slope to around 25 meters. A highlight is exploring the cave situated on the eastern side, which offers shelter for various reef fish and potential sightings of whitetip reef sharks. The route typically involves navigating through the unique geological formations, including swim-throughs and overhangs, while observing nurse sharks, hawksbill turtles, and large schools of snapper. The dive progresses around the islet, with the turn point determined by air consumption and current conditions. The safety stop is usually performed in the shallower, calmer sections of the reef, often among the upper boulder fields before ascending to the boat.

Underwater photography

St. Pierre offers excellent opportunities for wide-angle photography, capturing its dramatic granite topography and dense schools of fish. A wide-angle lens is recommended to frame the large boulder formations, arches, and the cave entrance effectively. For macro subjects found within crevices, such as lobsters, crabs, and cryptic species, a macro lens can be rewarding. Given the typical visibility of 15-25 meters, natural light is often sufficient in shallower areas, but strobes are beneficial for color rendition and illuminating subjects in the cave or deeper sections. Pay close attention to buoyancy, especially when navigating close to the granite formations, to avoid stirring up sediment or disturbing marine life. Patience is key for capturing shy cave dwellers or specific reef inhabitants like turtles and sharks.

Getting there & logistics

Access to St. Pierre typically involves flying into Seychelles International Airport (SEZ) on Mahé, then taking an inter-island flight or ferry to Praslin. St. Pierre Islet is located north of Praslin and is easily reached by boat from dive centers on Praslin, with typical boat rides being relatively short. Day trips to St. Pierre are commonly offered by local dive operators. Many dive centers on Praslin also offer PADI courses, and equipment rental is widely available. The site is often included in half-day or full-day diving excursions that might combine it with other nearby sites, depending on conditions and diver preferences. Marine park fees are typically around $15 per dive.

Safety & environment

The nearest recompression chamber is located on Mahé, about 44 km away, necessitating prompt evacuation by boat and then potentially by air or road in case of a serious dive emergency. Divers should ensure they have comprehensive dive insurance that covers emergency medical treatment and evacuation. Site-specific hazards at St. Pierre primarily include strong, unpredictable currents, especially outside of slack tide. Divers must be proficient in current management and maintain excellent buoyancy control to avoid being swept away or colliding with the granite formations. It is crucial to always dive with a local guide who is familiar with the daily tidal patterns and current predictions. Pay attention to briefings and follow the dive plan. Given the presence of a cave, appropriate training and experience for overhead environments are advised if planning extensive penetration.
