We had so much fun at Kaneohe Sand bar. It's a tiny island only visible on low tide but when its high tide the water is still shallow, Shallow like just on your thigh deep. It's famous for spring brake boat party.
We stayed there for a day and on the water the whole time. During summer the water is warm and turquoise, so inviting that you cannot get out of the water. We wanted to go back there so soon. It's the most beautiful place that I've ever been in Hawaii.
