Just heads up... Night diving was on south side of Fakarava called Tetamanu. There is only one operator offering night diving in the area. The pension is not cheap and condition is not what you expect for the price. Some people were not satisfied, but I had no problem since I prepared as much as I could.
Other than that, the divings were the best I've done so far. A lot of sharks and fish... healthy corals, mantas and napoleon wrasses. I miss the island so much that I am planning to go back in June for grouper spawning.
Meanwhile I'm going to Moorea for a week in March to check out what I missed last month. So excited!
