This dive site, Avana Passage, serves as a natural gateway into Ngatangiia Harbour on Rarotonga's east coast. Divers have the unique option to explore the outer reaches of this sandy passage or venture directly through it into the lagoon. The topography is a highlight, featuring stunning rock formations that evoke the atmosphere of an ancient underwater ruin, creating a dramatic and memorable backdrop for exploration.
The passage is particularly known for its resident lionfish and various species of eels, offering excellent opportunities for observation. Beyond these focal species, divers can expect to encounter a diverse array of reef fish typical of the Cook Islands' vibrant marine ecosystem, along with healthy coral growth clinging to the impressive rock structures.
The best time to visit Avana Passage is generally during the Cook Islands' dry season, from May to October, when the weather is stable and underwater visibility is often at its peak. This site is highly suitable for both snorkelers and freedivers due to its shallow average depth. Scuba divers should be mindful of potential variable currents, particularly when navigating through the passage, making it an engaging dive for all experience levels.
