If you are looking for a quiet yet beautiful resort this is your place. We chose Etu Moana after reading the other reviews and it was amazing to find it is actually better than the photos. The villas are well designed so they all face the sea, yet are all private due to the gorgeous plants and landscaping that make Etu Moana the tropical paradise it is. I wont repeat what others have wrote so I will just write what we enjoyed the most. We booked a lagoon cruise with Aitutaki Adventures (yellow boat) which was so good, we went again two days later. The lagoon has to be seen to be believed, the colour of the water, the fish, just amazing. Also the lunch on the cruise was absolutely delicious, you wont need dinner, believe me!
There are free beach cruiser bicycles at Etu Moana, and it was so nice to ride around on them. The pool is just fantastic, so warm and great for a midnight swim too. It was quite hot but we never needed the A/C because Jim (Jim and Joanne are the owners) has designed the villas so the air flows through, so even at night, we just left all the shutters open and the insect screens closed, so it was very comfortable, especially with the huge doors and screen looking right out to the sea from our bed, just paradise. In the evening grab some torches from the office and walk along the beach for 10 minutes and there is a lovely restaurant called "Te Vaaka", then when you walk back watch the huge crabs!! There are scooters at Etu Moana, so hire one (only $25 a day) and ride around the island, then climb to the highest point for a great view. You can ride the scooter most of the way up if you like.
But dont feel like you have to do anything if you dont want to, its so nice just relaxing at Etu Moana, watching the beautiful lagoon.
So if this sounds like you, just go, you wont be disappointed, I promise.
