J-3 - Cozumel

Manta Point is one of those dives that sticks with you, a cleaning station where the big oceanic mantas come in, along with their reef cousins. We’ve seen both *Mobula birostris* and *Mobula alfredi* here, each with their own patterns and markings, which is pretty special. You drop into the blue at the mouth of the pass, right where the currents meet, so it’s not a dive for the easily flustered. Visibility often hovers around 12 meters, sometimes better, sometimes a bit murky, but honestly, when a manta bigger than your car glides over, you don't really notice anything else. We love settling onto the coral at about 15 meters, just watching the show. The mantas cruise in, circle, and hover for their clean, sometimes so close you can count the remoras clinging to their undersides. It’s not just mantas either; we’ve seen dorado flashing past in the blue and the occasional sperm whale on deeper excursions further out, though that's a rare treat. This is a dive for experienced divers who are comfortable with current and want to witness the sheer grace of these giants up close.
