Star Cliff is a captivating dive destination located off the northern coast of Mauritius, not far from the popular diving hub of Grand Baie. The site takes its evocative name from the dramatic cliff-like reef structure that defines the underwater landscape. Sheer walls and steep drop-offs characterise this dive, creating a sense of weightlessness as you hover alongside vertical faces encrusted with marine growth. This is not an entry-level site – the wall diving and potential for current make it best suited to intermediate and advanced divers who are comfortable managing their buoyancy and air consumption in dynamic conditions. That said, the reward for the more experienced diver is exceptional.
The topography at Star Cliff is truly impressive. The reef begins in the shallows before plummeting steeply, offering both shallow reef exploration and deeper wall diving in a single entry. Rocky outcrops, ledges and swim-throughs punctuate the cliff face, providing sheltered niches where marine life congregates. Visibility is generally excellent in this part of Mauritius, often exceeding 20 metres on calm days, which allows divers to fully appreciate the scale and grandeur of the underwater cliffs.
The nutrient-rich waters around Star Cliff support a diverse and thriving ecosystem. The walls themselves are festooned with colourful soft corals, delicate sea fans and sponges in a kaleidoscope of orange, purple and yellow. Look closely and you will find nudibranchs, flatworms and juvenile fish sheltering among the coral growth.
The combination of wall, reef and open-water habitats within a single dive makes Star Cliff one of the most biodiverse sites in the north of Mauritius.
Conditions at Star Cliff can vary and divers should be prepared for some current, especially on the deeper sections of the wall. Surface conditions are generally calmer during the dry season, but the open-water exposure of the site means swells can build quickly if the wind picks up. Water temperature ranges from around 24°C in the cooler austral winter months (June to September) to a warm 28–29°C in the southern summer (December to March). A 3mm wetsuit is sufficient for most of the year, though a 5mm suit is appreciated in the winter months.
Visibility is a highlight of this site, frequently reaching 20–30 metres in good conditions. The best dives are typically made in the morning when the light is optimal and surface conditions are at their calmest.
Star Cliff can be dived year-round, but the most favourable conditions are found from April to November, spanning the transition from the wet season through the dry winter months. October and November offer a particularly excellent combination of warm water, calm seas and exceptional visibility. The summer months (December to March) can bring stronger winds and occasional cyclone-related swells, which may limit access on certain days, though the warmer water and increased fish activity can make those dives that do go ahead truly memorable.
