Why dive here
With 434+ marine species recorded in the area - including barracuda, blue sharks, dolphins, dwarf minke whales and great white sharks - Big Rock, Mauritius offers some of Flic en Flac & West Coast's richest cave diving. Water sits around 28°C.
Devils Point is a surprisingly varied spot, even if the visibility isn’t always what we’d call stellar. We’ve had days here where it’s a murky 5 metres, and others where it opens right up to a comfortable 10 or 12. You’re definitely coming here for the topography. The outer pin drops away, which can create some lively currents, but we love sticking closer to the middle. That’s where you find the belly of the reef rising to 5-8 metres, an ideal spot for a leisurely safety stop while you watch the school of Pacific sardines glimmer past. Our favourite part, though, is heading towards Humbug Bay. The boulders there are fantastic, riddled with deep cracks and holes begging to be explored. You’ll find a couple of legitimate caves too, nothing too deep, just enough to feel like you’re entering another world. Inside, we’ve spotted red rock lobsters tucked away, and often catch a glimpse of a New Zealand draughtboard shark resting on the sandy bottom. Keep an eye out for longtail garfish near the surface and those cheeky striped triplefins darting amongst the kelp. It’s a great site for divers who appreciate the structure of a reef and don’t mind a bit of a hunt for smaller creatures.
