Heron’s Wall - Iron Bottom Sound

Los Mogotes consistently ranks high on our list for Jardines de la Reina, and for good reason. It’s got that classic Caribbean feel, but elevated. You drop down to a mini wall, maybe 18 metres max, and the first thing you notice is the health of the coral. We're talking massive heads of Boulder Brain and Great Star Coral, a real testament to the park's protection. The real magic happens around the cavern overhangs. We've spent entire dives just exploring these, looking for the shy Graysby tucked into a crevice or watching a gang of Schoolmasters drift past. The big draw here, for us, is the schooling tarpon. They hang in the gloom of the overhangs, their silver scales catching the light just so, and it’s a genuinely impressive sight. Keep an eye out for schooling reef sharks too, they’re often patrolling the deeper edge of the wall. We love seeing the huge rainbow parrotfish crunching away at the reef, their colours just popping against the blue. This is a site that suits anyone comfortable with a gentle drift and a bit of cave exploration, offering plenty to see whether you’re peering into nooks or just admiring the wider reef scene.
