Snorkel two contrasting aquatic worlds in one day: a shallow ocean inlet rich with reef life, then a crystal cenote fed by freshwater. Small-group guiding and included equipment make this a hands-on, accessible coastal tour near Cozumel.

You step from an air-conditioned minivan onto hot coral rock; the wind off the Caribbean pulls at your hat and the lagoon ahead holds a green-blue calm that seems to breathe. At Yalku, seawater pools into a shallow inlet, riffed with patches of seagrass and small reef outcrops. Nearby, a limestone cenote waits—fresh, cool, and glass-clear—its walls carved by millennia of rain.
