Whale watching is a common sport most tourists partake in while here. If you visit Aitutaki between July and October, there is a good chance that you can spot them from the shorelines. Else, try going snorkeling or fishing, if you want to spot humpback whales. Kayaking is the perfect pick of activity for lazy afternoons. If you have some more energy, try going diving in the crystal clear waters of Aitutaki. You will get a good view of turtles, eagle rays, tropical fish, reef sharks and more. Snorkeling is a good way to go about exploring the diverse marine life in Aitutaki as well.
A popular activity that tourists participate in is island hopping, where they go around the lagoon and the small islands that lie along Aitutaki’s periphery in boats. This should give you some swimming and snorkeling opportunities as well. If you find some time to go shop after all the watersport activities, make sure you carry some water along, as it gets extremely hot here. You should be able to find shops selling interesting arts and crafts.
