Dredger Rock, Mahé - Inner Islands

Jadini is our pick for a really relaxed dive in Diani. It’s a gently sloping reef, starting around 7 meters and topping out at 15m. Perfect for taking your time. We love drifting along here, watching the resident green and hawksbill turtles munch on seagrass. You’ll also spot plenty of those longtail silverbiddies darting around, and the occasional bar-tailed flathead camouflaged on the sand. The coral formations aren't dramatic drop-offs, but they’re healthy and provide great little hideouts for a surprising number of nudibranchs, if you’ve got a keen eye. Visibility averages about 12 meters, sometimes better, but it’s rarely a washout. It’s a site that suits divers who enjoy a calm pace and don’t need the adrenaline rush of a drift or deep dive. Keep an eye out for golden trevally following larger fish, it’s always a treat to see.
