La Pointe Au Sel, Réunion: Diving the Outer Wall Drop-off

La Pointe Au Sel, also known as the Grand Tombant de la Pointe au Sel, is a deep wall dive located off the coast of Saint-Leu, Réunion. The site is defined by a steep outer reef drop-off that begins around 20 to 25 metres and plunges vertically to depths exceeding 70 metres. This is not a shallow reef system but rather a vertiginous wall with significant open-water exposure, demanding respect from the moment you begin your descent. You'll find yourself quickly moving from the calmer top of the plateau into the blue, where the water column itself becomes a dynamic environment.

The topography here is one of the more pronounced deep slopes in the region. Unlike some of the more sheltered reef dives, Pointe au Sel offers a raw, expansive feel, with the sheer face of the wall disappearing into the deep. As you follow the contour of the drop-off, the play of light changes dramatically, giving way to the deeper blues of the open ocean. This structure acts as a natural aggregation point, drawing in larger marine life that patrols the edge between the reef and the abyss, making every dive a potential encounter.

This site is consistently flagged for its currents, which can range from moderate to strong. The exposed position on the outer coast means it's directly influenced by oceanic flows, often resulting in a drift dive. When the current is running, it becomes a dynamic experience, carrying you along the wall while you focus on maintaining your position and observing the passing pelagics. Planning your dive with the current in mind is crucial for both safety and maximizing bottom time, as it shapes the entire profile.

The strong currents and deep water at La Pointe Au Sel are key factors in attracting a diverse range of pelagic species. Keep an eye out into the blue for schools of trevallies and tunas, often moving in synchronicity. Barracudas are also a common sight, either solitary or in shimmering formations. This site offers opportunities to encounter larger filter feeders such as manta rays and devil rays as they cruise the nutrient-rich currents, gliding effortlessly against the flow.

Deeper along the wall and off into the blue, the chances of spotting various shark species increase. Mako sharks and lemon sharks have been observed here, using the deep water as their hunting ground. While not guaranteed, the potential for these encounters adds to the allure of Pointe au Sel, reminding you that you are in a truly wild and active ecosystem. It's a reminder of the sheer scale of life in the open ocean, contrasting with the fixed life on the reef.

Beyond the large pelagics, the wall itself hosts resident species that are more accustomed to the deeper, current-swept environment. You might spot John Dory (Zeus faber) or the distinctive Napoleon wrasse (Cheilinus undulatus) moving along the reef structure. Triggerfish hold their ground against the current, and various jacks patrol the mid-water column, adding texture and smaller-scale activity to the grander pelagic show that often dominates this site.

La Pointe Au Sel is widely considered one of Réunion’s signature deep dives due to its dramatic wall and the consistent chance of encountering large open-ocean pelagics. Its exposed nature, greater depths, and more pronounced currents set it apart from the more sheltered reef sites found elsewhere on the west coast. This distinct character requires a specific level of experience and preparedness, making it a rewarding dive for those ready for the challenge.

The best time to experience La Pointe Au Sel is typically between June and November, when conditions often align to offer better visibility and increased pelagic activity. While visibility generally ranges from 20 to 30 metres, the sheer depth and dynamic nature of the site mean that even on days with slightly less visibility, the experience of drifting along this dramatic drop-off remains compelling. It’s a dive where you embrace the conditions and the wildness of the ocean.
