This dive site, Tongatok reef, is primarily utilized for Deep Diver Training due to its unique topography. The reef initiates at a shallow 5 meters and descends rapidly to depths exceeding 40 meters, offering varied depth profiles for training and exploration. The extensive sandy slope is adorned with vibrant and healthy coral formations, creating a scenic underwater environment for divers.
The marine life at Tongatok is consistently observed, with sand eels frequently spotted, even in the deeper sections of the sandy slope. Triggerfish and lionfish are common residents, appearing on nearly every dive, contributing to the site's biodiversity and photographic opportunities. The healthy corals also provide a habitat for various smaller reef fish and invertebrates.
While specific seasonal highlights are not provided, the consistent presence of marine life and healthy corals suggests good diving conditions year-round. Divers should be mindful of the rapid depth changes, especially during training. Its suitability for deep diver training also makes it an excellent site for freedivers looking to practice deeper dives, while the shallower reef top offers good conditions for snorkeling.
