Best for beginner divers, 3-45m, boat entry, moderate current.
Waelmu Cave on Wangi-Wangi Island offers a combination of reef and cave diving with depths ranging from 3 to 45 metres. The site features a consistent visibility of 30 metres and warm water temperatures between 26 and 30C. As an overhead environment, the cave requires divers to remain close to their guide and avoid direct ascent. While the site is accessible to beginners, the deeper sections and potential for moderate currents require careful planning. The surrounding reef habitat supports a variety of reef fish and invertebrates. Boat access is required to reach the site, and morning departures are recommended for more predictable currents and optimal lighting.
