All diving off Maui is on the western shore - either northish or south - between Maui and Lanai. Mostly around Molokini.
Mike Stevens and Ed Robinson best dive boats operators.
Lots of coral bleaching.
Reef and white tip sharks, trops, turtles, one med. sized Manta (my first Manta!), moray eels, slipper lobster, striped shrimp.
