Strolling ocean side at Lahaina, Maui, you might as well take a little dip and enjoy the warm Pacific. The water here is so clear you can see coral and goatfish from the shallows by just looking down.
When the swell picks up, surfing is good. When the swell is down, snorkeling and diving are good. If you are not an ocean person, Lahaina town is good.
Bottom line–Maui no ka oi.
