Olowalu. Mile Marker 14. We’ve probably parked here a dozen times, gearing up next to the road. It’s got one of the easiest shore entries on Maui, just a quick wade in. What we love about Olowalu is the scale of the coral; it's a massive, ancient reef that stretches out into these incredible canyons. You can spend a whole hour just finning through those formations, spotting arc-eye hawkfish perched on stony corals. Visibility here averages 14 metres, and it’s a pretty shallow dive, maxing out at 9m. We usually see a handful of green sea turtles – it’s definitely one of their preferred hangouts. Look closely for snakehead cowries tucked into crevices. While it’s not a drift dive, there can be a gentle push sometimes, so keep an eye on your bearings as you navigate the coral maze. It’s a site that really suits new divers or anyone who just wants a relaxed, beautiful shallow dive without much fuss.
