Efate divides neatly into two distinct sub-areas: Port Vila, which holds the bulk of sites and includes the region's wreck collection, walls, and bommies, and Moso Island, a smaller cluster offering reef diving and strong drift conditions. The site mix runs from shallow beginner reefs to deep advanced wrecks such as the Tasmin Flying Plane and the Star of Russia. Reef life is well documented, with the Chromodoris Nudibranch, Blackback Clownfish, Crocodile Fish, and Giant Moray consistently observed. Currents at Moso Island demand some experience, while sheltered Port Vila sites suit newer divers well.

Water stays warm throughout the year, peaking in the early months before cooling slightly through the southern-hemisphere winter. April and November stand out as particularly favoured periods, likely reflecting a balance between settled conditions and good visibility. The cooler mid-year months are still comfortable for diving, though sites exposed to current, such as Moso Drift Dive, will demand more care.

The Chromodoris Nudibranch and Blackback Clownfish are among the most frequently sighted, while the Crocodile Fish, Giant Moray, Turkey Moray, and Titan Triggerfish are all commonly encountered. Indian Lionfish and Regal Angelfish round out the reef character, and the Day Octopus turns up with reasonable regularity.
A good portion of Efate's sites are rated beginner-friendly, including Mele Reef, Pango Wall, Hideaway Island, and Konanda Reef. These offer accessible depths and manageable conditions. Intermediate and advanced divers are catered for with drift diving at Moso Island and deeper wrecks such as the Semele Federsen and the Star of Russia, so the region works across a range of experience levels.
Port Vila accounts for the majority of sites and offers the greatest variety, from shallow beginner reefs and cave systems like Cathedral to deep wrecks including the Tasmin Flying Plane. Moso Island has a smaller number of sites focused on reef diving and is characterised by stronger currents, making the Moso Drift Dive a highlight for intermediate divers seeking a more dynamic experience.
The majority of Efate's sites require a boat to reach, and several operators serve the region, including Big Blue Dive Shop, Hideaway Dive Shop, and Tranquility Island Eco And Dive Resort. Hideaway Island is a notable exception, offering both shore and boat entry, making it one of the more flexible access points in the region.
