Napili bay is located in Oahu, Hawaii. It is a beautiful place to be and enjoy the beautiful waters of Hawaii. There are so many beautiful turtles you can see, snorkel and take pictures with. It was probably one of the most amazing things I have seen in my life. It is so beautiful to see the turtles in their natural habitat. It is amazing how calm and comfortable around people they are. It is a great place to go with friends and family I hope you get the chance to experience it someday.
