Our amazing snorkel spot the last day of the cruise-Ni'ihau Island, near Kauai. I saw amazing fish, sharks, and the best part-we swam with spinner dolphins spontaneously when we came upon a huge pod of them. When I was snorkeling I could hear them under water. And when we were just watching them they were jumping a few feet out of the water and spiraling and slapping back down, going on their backs and slapping their tails, and jumping in rainbow like arcs...it was AMAZING.
