Why dive here
Keauhou Bay is a drift dive where divers can encounter blue sharks, sea turtles and sperm whales. Water ranges 25-28°C, warmest August, September, October.
Keauhou Bay, right off the Sheraton, is a solid little spot for an easy beach entry, especially if you’re staying nearby. We’ve always appreciated how straightforward it is to gear up and just walk in. The reef maxes out around 17 meters, so it’s a calm, shallow dive, perfect for stretching out a long bottom time. During the day, we often see parrotfish munching away on the coral, and the occasional whitetip reef shark cruises by. Keep an eye out for eagle rays gliding past in the blue. Our favorite time to dive Keauhou, though, is after sunset. That’s when the mantas often come to feed on the plankton attracted by the resort lights. Descending into the darkness and having one of those giants gracefully circle just inches away is a moment that genuinely sticks with you. You'll want to watch for boat traffic in the middle of the bay, but closer to shore, it’s usually clear. This is a great dive for anyone looking for a relaxed outing, day or night, without the hassle of a boat trip.
Safety Notes
Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.
