Agakauitai – Gambier Islands

Site Overview

Agakauitai is a submerged pinnacle rising from the deep waters of the Gambier lagoon, creating a dramatic underwater seamount that concentrates pelagic and reef life in a relatively small area and produces some of the most exciting diving available in this remote archipelago. The pinnacle rises from the lagoon floor to within a few metres of the surface, its vertical faces covered in colourful corals and filter-feeding organisms that create thriving habitat for diverse marine communities. Massive schools of jacks form dense aggregations around the pinnacle, their silver bodies creating shimmering clouds of fish that patrol the water column above the formation in coordinated hunting patterns. Dogtooth tuna use the pinnacle as a cleaning and hunting station, their powerful torpedo-shaped bodies rocketing through bait fish concentrations with explosive speed. Whitetip reef sharks rest on the sandy areas at the base of the pinnacle, their distinctive white-tipped fins and relaxed demeanour creating excellent photographic opportunities in the clear Gambier waters. Eagle rays make regular passes around the pinnacle, their broad wings carrying them gracefully through the nutrient-rich water as they search for food on the sandy areas between coral formations. The isolation of the pinnacle means that marine life remains completely undisturbed by human activity, creating authentic encounters with wild animals behaving naturally in their pristine habitat.
