Even right before setting out we noticed sea turtles, but after from dock we saw quite a few dolphins who raced together with us and small flying fish called sea robins.. SO Neat! Returning to Kauai upcoming 12 months just for this vacation. Mahalo! The beaches are rough and rocky, https://niihau-boat-tour77665.tribunablog.com/new-step-by-step-map-for-snorkeling-niihau-island-49205771
