    Irvin's Mantas lives up to its name, though not always in the way you might expect. It’s a good spot to catch mantas cruising by, especially on an incoming tide when the current brings them in for a clean. We’ve found the best strategy is often to find a good vantage point, settle in, and let the show come to you. You'll likely see Hayashi's cardinalfish darting amongst the staghorn corals, and if you have an eye for the small stuff, look for the adorned dwarfgoby. This isn't a high-adrenaline drift, but more a patient wait for those majestic fly-bys, making it ideal for photographers or divers who prefer a more relaxed approach.

    Safety Notes

    Strong currents typical this month (avg 35 cm/s). Good buoyancy control essential.
