Iglesia is a Coiba reef built around rock towers, sand cuts, and ledges that give the dive a cathedral-like feel. It rewards slow movement and good trim, with enough structure to keep the route interesting without turning it into a hard swim. The fish life is the main draw: reef sharks, turtles, jacks, snapper, barracuda, eels, and smaller reef creatures all work the cracks and open edges. A little current can sharpen the action, so the best dives are the ones where the guide lets the site breathe instead of forcing a straight line.
