Blue World Diving

Mafia Island, Tanzania

The team at Blue World Diving are what makes diving in Mafia Island truly shine. We’ve known them for years, and they’ve built a reputation for being incredibly knowledgeable about the local reefs, particularly around Chole Bay. If you’re looking for a dive operation that feels more like diving with friends than a commercial enterprise, they’re our pick. They’re PADI 5-star, so you know the training standards are solid, but it’s their passion for Mafia’s delicate ecosystem that really stands out. Diving with Blue World often means small groups, which we appreciate for a more intimate experience. We’ve spent many a surface interval chatting about anything from the latest shark sightings to the best local coffee. They’re fantastic at spotting the small stuff, like leaf fish swaying in the current or a well-camouflaged stonefish – details you might miss if your guide isn't paying close attention. We’d suggest opting for an early morning dive with them; the light filtering through the water into the coral bommies, often accompanied by schools of snapper waking up, is simply magical. They’re also excellent at tailoring dives to conditions, finding the sheltered spots if the wind picks up, ensuring you always get the best of what Mafia has to offer that day.
