Namena: A Marine Scientist’s Perspective on One of Fiji’s Best Dive Sites

Diving Fiji's largest marine reserve

Some places underwater stop you mid-fin kick. Namena Marine Protected Area is one of them.

Rising from deep blue water off the southern coast of Vanua Levu, Namena feels alive in a way that’s increasingly rare today on coral reefs worldwide. The first thing most divers notice isn’t a single species or standout moment — it’s the abundance. Fish everywhere — Large schools of fish moving across ridges and drop-offs. Coral in exceptional condition with a spectacular diversity of marine creatures living amongst its branches. Depending on the sea conditions and season, you may also spot spinner dolphins or pilot whales being trailed by silky sharks when heading to Namena from Savusavu.

As Fiji’s largest marine protected area, Namena is not only one of the country’s most important conservation successes — it’s among the best diving Fiji has to offer.

Why is Namena Marine Protected Area so special?

Namena Marine Protected Area (MPA) is Fiji’s largest no-take marine reserve. It’s 60 km² protects a vast horseshoe-shaped barrier reef and deep-water channels that sit at a biological crossroads, where it is bathed in nutrient-rich ocean currents. The area has been fully protected since 1997 — no fishing — providing refuge for fish to flourish and multiply. That large-scale and long-term protection is key to building coral reef complexity and supporting the food webs that attract larger marine species.

Biodiversity on a spectacular scale

Namena is renowned for its vast schools of pelagics and on a good day, divers can expect:

• Regular sightings of grey reef sharks and whitetips

• Large schools of barracuda cruising near drop-offs

• Dense aggregations of trevally, unicorn fish, and fusiliers

• Occasional hammerhead shark and tuna using currents to hunt 

• Iconic reef fish like groupers and humphead wrasse, and occasionally bumphead parrotfish

What makes Namena special isn’t just the impressive species list — it’s the structure of the ecosystem. Ecologically important predators and grazers are present. Reef slopes and bommies are covered in hard corals, soft corals and gorgonians and teeming with reef life.

This high biodiversity is why Namena has rightfully earned its nickname: “Fiji’s Galapagos”.

Ridge-to-reef connection: From seabirds to coral reefs

The reserve’s benefits extend above the surface. Namenalala island is nestled within the reserve and provides important nesting habitat for the critically endangered hawksbill turtle and over 600 pairs of red-footed boobies. These seabirds play a critical role in reef health and shaped my personal connection to Namena.

As a scientist interested in connections between the land and the sea, I spent many enjoyable hours researching how seabirds on land influence the coral in the shallows below. Nutrients from seabird guano wash into surrounding waters, acting like a natural fertiliser that boosts coral growth. Corals growing below the seabird roosting sites grew four times faster than corals without guano-enriched seawater. The fish also played a key role  — because Namena has healthy fish populations, they graze the seaweed that would grow on the reef and help keep the coral healthy.

It’s a reminder that reefs don’t exist in isolation. Healthy oceans depend on healthy islands, forests, birds — and protection across the whole ecosystem.

Namena is a rare place where these ecological connections are still intact.

Experiencing Namena while staying in Savusavu

Namena is accessed by boat with several dive operators from Savusavu. When the south-east trade winds are strong, the sea conditions can be challenging to access Namena reserve. Hence I recommend that divers keen to experience Namena allow extra time in Savusavu to increase your chances of diving this premier dive area.

For guests staying with us at Latui, car pick-up can be conveniently arranged from the bottom of our drive and transport to the dive shop, making dive days seamless and unhurried — just the way they should be to enjoy your time on the reef.
