Dive Site Overview

Imagine descending into Mango Bay, a wide, shallow expanse fringed by vibrant reefs along its coastlines. This site offers a dual experience, starting with expansive coral heads in the shallower sections, ideal for initial skill practice or leisurely observation, with depths beginning around 2 m (6.5 ft).

Taking time to observe their synchronized, fluid movements, perhaps kneeling briefly in the sand beneath them, is an experience that few people forget. Beyond this captivating spectacle, a diverse selection of hard corals provides a rich, colorful backdrop.

These formations harbor a variety of smaller reef inhabitants, ensuring that every dive offers new details to uncover. Mango Bay caters effectively to both Open Water Diver training and recreational dives.
