Roche Grand Maman

Roche Grand Maman sits off Praslin, a granite boulder field that feels like diving through a submerged sculpture park. We usually find ourselves exploring depths from 12 to 20 metres here, weaving through massive, rounded rocks covered in soft corals and sponges. Sunlight filters through gaps in the boulders, creating these incredible shafts of light that dance on the sand patches below. It’s a site where you really need to slow down, peer into every crevice, because that’s where you’ll find the Small-eyed Squirrelfish tucked away or a grumpy Bennett's Pufferfish trying to blend in. Visibility is generally excellent, often 25 metres plus, especially if you get there before the afternoon winds pick up. We’ve had some cracking encounters with Giant Trevally here, often circling the deeper edges of the rock formations, and the schools of fusiliers can be so thick they genuinely block the view for a moment. Keep an eye out for the Hound Needlefish cruising just below the surface, too. Roche Grand Maman is perfect for divers who appreciate intricate topography and a slower, more observational dive, rather than chasing pelagics in the blue. It’s a site that rewards repeat visits; you always spot something new.
