Nanas Reef - Halmahera

Purple Reef, just a quick boat ride from Taveuni, definitely earns its name. Drop down and you’re immediately enveloped in a soft, lilac glow, thanks to the vast fields of lavender-hued soft corals. It's not just a splash of colour, it’s an entire landscape painted in shades of violet. We love drifting along the reef edge, watching the reef gently slope away into the blue. The rock formations here are fantastic, creating countless nooks and crannies where we’ve spotted everything from inquisitive moray eels poking their heads out to sleepy turtles tucked into ledges. While the visibility averages a decent 18 metres, we find it’s even better on a calm morning, when the sun filters through the water and really makes those purples pop. Keep an eye out for the smaller stuff too, like the ornate pitar venus clams nestled in the sand patches. It’s a great site for photographers, especially macro lovers, but honestly, anyone who appreciates a truly distinctive coral landscape will enjoy this one.
