    StandoutExceptional marine biodiversity

    Heron’s Wall, a more recent find in Iron Bottom Sound, is a shallow wall dive that really delivers. We’ve found the hard and soft coral coverage particularly impressive in the shallower sections, just stunning stuff. Look for the tiny details here, like the Yellow-red Pygmygoby and the comical Red-streaked Blenny. Euna Zio, who found the site, apparently named it for the Herons flying overhead – and we believe her. It’s a solid pick for macro lovers and photographers who appreciate a healthy reef.

    Safety Notes

    Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
