Makena Landing has good parking, lots of kayaks and snorkelers in the area. You surface swim to the right just at the first house and dive down. This is a great place to dive with lots of sea turtles to film and plenty of triggers, wrasse, puffers etc. We explored one of the caves but missed the first cave where there were 5 sleeping reef sharks. Take your time as there's so much to explore and every turn is an amazing view of coral, light and fish.
