About Arorangi Passage
Arorangi Passage is a high-energy passage dive on Rarotonga’s west side, where the shallow channel funnels through reef and opens to canyons and swim-throughs on the outside. The passage is dredged for small craft, so the site sits in a live waterway with strong flow and boat traffic to respect. It suits experienced divers who want structure and movement more than a relaxed reef cruise.
