Conditions & Currents

Humann Nature is characterized by significant ocean currents, making it primarily a drift dive site. These currents can be strong, requiring divers to be proficient in drift diving techniques, including negative-buoyancy entries. The dive briefing will detail current direction and entry procedures, often involving entering the water as the boat reverses and immediately descending to avoid surface currents. Physical cues like the direction of fish swimming and soft coral movement help gauge current direction and strength underwater. Visibility can be exceptional, particularly during the cooler months, though warmer periods may see a reduction due to plankton blooms. Divers must pay close attention to air consumption and maintain strong situational awareness, as conditions can change rapidly. The boat tracks divers from the surface, ensuring safe pickup at the end of the dive, minimizing t

Dive profile & how the dive runs

Divers at Humann Nature typically execute a negative buoyancy back-roll entry, immediately descending to avoid strong surface currents. The dive leader will often enter first to assess the current, then guide the group along a wall, keeping the reef either to the left or right. The profile is multi-level, starting deeper, potentially around 32 meters (100 feet), then progressively ascending shallower as the dive progresses. Divers should stay close to the dive leader, avoiding going deeper or ahead. Observations of fish behavior and coral orientation provide clues about current direction and potential upwellings or down-currents. The dive concludes with a three-minute safety stop, usually around 5 meters, with the boat positioned approximately 100 yards from the wall to facilitate a surface pickup.

Underwater photography

Drift diving at Humann Nature presents unique challenges and opportunities for photographers. Due to potentially strong currents, cradling your camera during the back-roll entry is crucial, and rapid descent is often required. Wide-angle lenses are ideal for capturing the expansive wall formations and the schools of fish often present in the currents, while macro lenses can be used for the diverse critter life found during warmer months. Mastering buoyancy and finning techniques is paramount to avoid contact with the reef and to maintain stable shots while moving with the current. Keep an eye on your surroundings, as large pelagics like manta rays or sharks can appear from the blue side of the wall. Streamlining your gear, including strobes, is also important to reduce drag and conserve air during the drift.

Getting there & logistics

Access to Humann Nature is typically via liveaboard, which are best for reaching remote sites in Fiji's Bligh Water region. These trips often depart from major Fijian ports, with international flights arriving at Nadi International Airport (NAN). Liveaboards commonly offer itineraries lasting between 7 to 10 days, combining sites like Humann Nature with other renowned diving areas to showcase Fiji's diverse marine environments. There are no specific park fees mentioned for this site, but general liveaboard costs cover permits and logistics. Divers should confirm their trip details with their operator.

Safety & environment

Diving at Humann Nature involves drift diving in potentially strong currents, necessitating advanced dive skills and excellent buoyancy control. Divers should ensure their insurance covers drift diving and potential medical evacuation. The nearest recompression chamber is located in Suva, requiring potentially significant travel time in an emergency. Always adhere strictly to the dive briefing, stay with your group, and monitor your air consumption carefully. If you surface unexpectedly or have a problem, signal the boat and wait for pickup; do not attempt to swim back to the reef against the current. Due to the dynamic nature of the site, prior experience with drift diving is highly recommended to ensure both safety and enjoyment.
