Why dive here
With 183+ marine species recorded in the area - including barracuda, dolphins, sea turtles, sperm whales and lionfish - Criminal Rock offers some of Inner Islands's richest wall diving. Water ranges 27-30°C, warmest March, April, May.
Criminal Rock, just north-east of Praslin, is one of those sites that always delivers. It’s a granite boulder field, pure and simple, but the way the rocks are piled creates these fantastic swim-throughs and gullies, all at a really comfortable depth, usually maxing out around 17 metres. We love dropping in here on a sunny morning; the light filters down through the cracks, making the water sparkle. You'll see so many fusiliers here, especially the Blue and Gold, schooling so thick they sometimes block out the view of the next rock. We’ve had a few calm days where the barracuda hung around the deeper edges, watching the chaos. Keep an eye out for the smaller stuff too: we've spotted Flaming Blennies tucked into crevices and Zebra Eviotas darting around the sandy patches between the rocks. It’s a great spot for photographers who like to get up close with reef fish, and it’s generally sheltered enough that even newer divers will feel comfortable. Just be mindful of the boat traffic if you're exploring the shallower tops of the rocks.
