Toho II, wreck - Prony Bay

There’s a reason Neptune’s Arm keeps coming up in conversations about Mozambique diving. It's not just a healthy reef; it’s a sprawling, vibrant city of coral. We’re talking about vast fields of hard corals here, specifically the branching staghorn and the massive potato groupers that hover amongst them. Dive over a bommie and you might catch the flash of a Napoleon wrasse gliding by. We love the feeling of just drifting, watching the intricate patterns of the honeycomb corals and the subtle glow of fluorescence grass coral. Visibility is generally excellent, making it easy to spot the argus groupers lurking in the shadows. This spot suits divers who appreciate truly healthy coral ecosystems and aren’t afraid of a bit of remote travel for the reward. Dive this site mid-morning; the light plays beautifully through the water, illuminating the coral gardens.
