The Molokini Crater is located 10 miles south of Maui. This is the best snorkeling spot of all of Maui. The water visibility is always 100 to 180 feet deep. We have never encountered such clarity ever. You are not allowed to walk on it. The inside part of this crater saves you from the crushing waves and there is never a sand run off. We just wish the fish count was greater. I guess it is not what it used to be because of dozens of boat excursions there everyday.
