Boss Reef - Southwest Coast

Edna’s Anchor isn't a deep dive, but it's one of our favourite spots for a relaxed morning out. You follow the reef edge along a gentle slope, maybe 20 metres down, until the sand opens up. That's where you find the anchor, a big, imposing thing wedged between two coral heads. It’s a proper piece of history, not just some random debris, and knowing the schooner Edna sank later in Atiu adds a cool dimension to it. The anchor itself is absolutely encrusted – we’re talking serious coral growth, home to countless delicate blennies poking out and small territorial damselfish darting around. Look closely and you’ll spot eroded cowries tucked into crevices. We’ve had great luck finding false-eyed pufferfish hovering nearby, almost posing. The visibility here is usually excellent, around 26 metres, so you get a really clear view of the whole scene. It's a calm dive, perfect for photographers or anyone who likes to take their time exploring a smaller site with a great story. We often finish up watching marbled parrotfish browse the nearby staghorn corals.
