Aroa beach, on Aitutaki Island, Cook Islands is really a stunning beach and it's in the top ten beaches in the world. Surrounded by a blue lagoon, snorkeling and scuba diving are exceptional here. Even if it's not easy to reach this beach, it's totally worth it.

Aitutaki Lagoon is an excellent South Pacific beach destination. The main island of Aitutaki is small enough to explore by bike and there are a number of good spots just for laying on the sand and swimming. The beaches along the north-west coast of the island are the most picturesque and swimming and reef exploring is also good.
