Why dive here
With 177+ marine species recorded in the area - including barracuda, bull sharks, dolphins, eagle rays and nurse sharks - Agua Negra Cozumel offers some of Cozumel's richest reef diving. Water ranges 27-30°C, warmest August, September, October.
Agua Negra isn't your typical reef dive; it's Cozumel’s blackwater offering, and honestly, we’re completely hooked. You head out a few miles from shore, drop in at dusk, and spend your dive at a maximum of 18 meters, drifting in the inky blackness. It feels like you’re floating in space, with only the glow of your torch to illuminate the incredible miniature world migrating up from the deep. We've seen some utterly bizarre and beautiful things here. Think tiny larval crabs and squid, transparent eel larvae, and juvenile fish like baby swordfish or sailfish, no bigger than your finger. The way they reflect your light, darting through the darkness, is mesmerizing. It’s a completely different rhythm to reef diving, quieter, more focused. We’d recommend it for divers who are comfortable with good buoyancy and night diving, and who appreciate the truly unique, delicate side of marine life. It’s a special kind of hunt, spotting those almost invisible creatures in the vast open ocean.
