Tarpon Caves - Lighthouse Reef

Tarpon Caves, over on Lighthouse Reef, is one of those dives that sticks with you. It’s a wall, mostly, but the real draw is the tunnel system. You drop into an entrance at 12 meters, then follow a vertical passage that opens up into a much deeper crevice, down around 30 meters. It’s a proper swim-through, not just a crack. The second chute leads you up, making for a nice ascent. We noticed fewer soft corals on the walls here compared to somewhere like Long Caye, but the hard coral structures felt more substantial. Keep an eye out for barracuda; they’re often quite curious here, following you along. It's a good pick for divers comfortable with enclosed spaces and deeper profiles.
