Cook Islands: Rarotonga – snorkeling at Aro’a Beach

The entire western shore of the Rarotonga island is a marine reserve where boats are not allowed and the fish is abundant behind the line of coral reef. While the corals here are not as produce or beautiful as on some other pacific islands, the fish of most unimaginable rainbow colors are everywhere and almost swim up to you – butterflyfish, angelfish, pufferfish, parrotfish, goatfish, moorish idol, unicornfish and so many other. The most bizarre colored ones are called Picasso Triggerfish.
