🇨🇰 Cook Islands

The Cook Islands offer mostly saltwater diving in the South Pacific, with most trips based around Rarotonga and Aitutaki. Around Rarotonga, divers typically find reef slopes and drop-offs close to shore, with clear lagoon conditions in calmer bays and more current at exposed sites. Aitutaki’s lagoon is known for shallow-to-mid depth reef diving, where visibility is often good and you can plan both relaxed dives and deeper profiles depending on the site. Conditions vary with season and weather, so expect planning around wind and swell. If you’re comfortable with short boat rides, this is a good destination for warm-water reef diving without needing advanced logistics.
