In the Cook Islands, the snorkeling off Aitutaki Island is known for its magnificent lagoons with diverse coral and marine life. Most of the waters are a protected marine reserve, so there are few boats around. The lagoons are the remnants of a sunken volcano. When snorkeling at Aitutaki Island, keep an eye out for the masked butterfly fish and blue chromis.
The best snorkeling on Aitutaki Island can be found just north of the Pacific Resort, which is popular for spotting the dangerous stonefish. Another good snorkeling dive site is the O'out Beach off little Akitua Island.
To reach the Aitutaki Island snorkeling by air, fly into the Rarotonga International Airport (RAR) located on the northwest side of the Rarotonga Island. There are direct flights at least once a week from Sydney, Auckland, Tahiti (Air Tahiti) and Los Angeles. In addition, there are inter-island flights on Air Rarotonga to the main Cook Islands including Aitutaki. There is no separate depature tax since it is included in the international airline tickets.
Overall, Aitutaki Island is the 2nd most popular snorkel dive spot of all 3 snorkeling dives in Cook Islands.
