Dive-site story
Located off the rugged limestone cliffs of western Guam, Barracuda Rock features dramatic volcanic and coral formations that plunge toward the ocean floor. Divers descend along stepped reef terraces and rocky ledges undercut by surge channels and small caverns. Clear oceanic water frequently sweeps past the promontory, attracting pelagic predators that cruise along the drop-off while macro critters find shelter inside crevices along the rock face.

Caverns and swim-throughs carved into the hard limestone structure
