AMAZING Coral!!! parrotfish, clownfish boxfish, angel fish, pufferfish, star fish, loads of sea cucumbers, bluefin trevally, moray eels, turtles (I heard you can see small whitetip reef sharks - but unfortunately we didn´t).
Current can be a bit strong, we had fins, so we were OK, but others without seemed to struggle towards the end of their snorkel trip.
Everyone keeps talking about coral shoes/booties but I think its best to go au-natural if you aren´t wearing fins as despite being told not to, people who are perhaps less comfortable, do stand on the coral
In fairness, it doesn´t seem to matter where you go, the underwater world of Rarotonga is pretty darn spectacular. From a snorkelling perspective you won´t be disappointed (unless the weather isn´t on your side, as this can affect the visibility).[googlemap][/googlemap]
