I am currently on Oahu and I have been to Hanauma Bay 3x, and several other places around Oahu.
I have a couple days left and I would like to take a day trip centered around snorkeling. I am willing and able to fly to one of the other islands to snorkel.
I just would like the absolute best spot(s) to snorkel during this time of the year. I know marine life viewing is not guaranteed, but I would like to increase my chances. We have not seen any turtles yet, dolphins would be amazing, and I personally would like to see a juvenile shark. o_O
Also, what are the times of day/night to go?
And any other tips appreciated!
