Schweriner See - Bornholm

Hakau Mounu is one of those spots we always make time for when we’re in Tongatapu. It's not about big pelagics here, though we’ve seen a few curious reef sharks pass through. This site is all about the reef itself, particularly the sheer density of small, colourful fish against the vibrant hard corals. Drop in and you're immediately enveloped by schools of Blue Green Chromis, a shimmering, living cloud. We love drifting along the reef edge, keeping an eye out for the Dotted Wrasse and the shy Black Blenny darting amongst the coral heads. Look closely, and you’ll often find a Freckled Anglerfish perfectly camouflaged on a sponge – they’re masters of disguise. The coral formations here are impressive, especially the Staghorn, providing endless nooks for juvenile fish. We’ve found the best light for photography is usually mid-morning, around 10 am, when the sun isn't directly overhead but still bright enough to make the colours pop. It’s a gentle dive, perfect for photographers or anyone who just wants to slow down and truly observe reef life.
