There's enough on Maui to keep you busy above ground, but things can get overwhelming when you start looking below sea level. There are colonies of sea turtles, pods of dolphins, living coral reefs and hundreds of species of tropical fish. Makena Charters show you just a small portion of what there is to see: underwater caves, the reefs off Molokini, a sunken World War II tank, Turtle Town and more. The underwater action is nonstop. This is one of the last remaining six-person dive boats. Beginners and certified divers are welcome.
