    Tarpon Channel is a lot more than just a nursery for silvery torpedoes, though we’ll get to those. It’s a proper channel dive, sitting between the two Corn Islands. That means currents. Not ripping, but enough to make it a drift, often with a slight chill as deeper water funnels through. We usually drop in just off Little Corn, letting the push carry us toward the open ocean. The depth is perfect for newer divers, generally staying around 12-15m. Our favourite part? The sheer density of schooling fish. French grunts form shimmering walls, so thick they sometimes make the light dance. Look closely at the channel floor; we’ve spotted massive Florida cones inching along and those surprisingly camouflaged rockfish. And yes, the tarpon. They’re usually there, circling in the deeper parts of the channel, sometimes twenty strong, sometimes just a few massive individuals gliding past, their scales catching the light like hammered silver. We often see barracuda too, sleek and still, eyeing the commotion. It’s a simple dive, but incredibly rewarding for its big fish encounters and the immersive feel of being swept through a living corridor. Best done on an incoming tide for the clearest water and a gentle drift.
