Dive Site Location & Key Facts
Dive Site Overview
Manta Bommie, named for the iconic Manta Lodge, functions as a critical marine hub centered around three prominent rock outcrops, known as 'The Group'. This dive location offers a primary depth range of 5-15 m (16-50 ft), making it suitable for Open Water, Advanced, and even snorkeling experiences.
During the austral summer, from October through April, these bommies become dynamic cleaning stations, actively drawing in migrating reef manta rays for exceptional close encounters. The interaction between cleaners and large pelagics is a highlight, unfolding consistently at shallower depths. Beyond the peak manta season, divers can often spot large Black Blotched Rays, Leopard Sharks, and various octopuses, frequently seen seeking mates among the formations.
Year-round, the site consistently hosts resident green turtles, bamboo sharks, wobbegong sharks, and a diverse array of other rays. While its vibrant marine life is a significant draw, this exposed area is frequently prone to significant current and swell.
These conditions present a challenging dive, demanding careful planning and appropriate experience to navigate successfully.
