Black Rocks Lagoon

Black Rocks Lagoon, despite its name, is more of a sheltered bay punctuated by dramatic volcanic rock formations. We love its versatility; the shallow inner lagoon, fringed with kelp, is a mellow spot to just drift and watch snapper cruise through, sometimes even finding a green wrasse peeking from the weeds. Then you've got the outer reef, a series of rocky pinnacles and gullies that really open up a different experience. We've had some memorable encounters here, particularly with shortfin makos on the deeper edges – not an everyday sight, but it happens. Visibility can vary, often around 10-12m, but the light filtering through the kelp forests even on an overcast day is something special. Our pick for an afternoon dive is to start shallow, exploring the crags where oblique-swimming triplefins dart, then venture out if conditions allow. Just be mindful of the swell on those outer pins; it can get pretty lively out there.
