Avana Passage is a Cook Islands passage dive that combines a sandy channel, lagoon access, and a deeper outer drop-off. The site feels like a set of connected dive sections rather than a single small reef, with rock formations, coral growth, and tidal movement shaping each option. It suits divers who want a passage, a lagoon drift, and a deeper outer ridge in one place, but it rewards good timing and an eye on the current.
