About Octopus Reef
Octopus Reef is a boat-only northern Guam site near Uruno Point with surge-cut channels, vertical walls, tunnels, and a steep amphitheater-shaped slope. It is usually run as a drift dive in very clear water and rewards divers who stay relaxed through the moving water and work the route instead of rushing it. The reef highlights include octopus, large wrasse, parrotfish, grey reef sharks, eagle rays, and sea-fan-and-spongy wall sections that give the site its dramatic shape.
