Dive-site story
Situated along the outer reef near the entrance to Apra Harbor, Blue and White offers a mix of hard coral formations, gentle sand flats, and outer drop-offs. The site takes its name from nearby navigational markers that guide vessels past the reef line. Divers commonly encounter sea turtles resting among massive Porites coral heads and schooling reef fish feeding in the coastal current.
Extensive hard coral gardens along the outer harbor slope
Regular encounters with green sea turtles and resting whitetip reef sharks
Clear oceanic visibility typical of outer reef formations in western Guam
Location
