Yellow Wall boat drift off Cocos Island with clear water and pelagics.
Yellow Wall boat drift off Cocos Island with clear water and pelagics.
Cocos East, also called Yellow Wall, is Guam's east-wall boat drift off Cocos Island, with a long reef wall, clear water, and dense yellow sea fans. It is an advanced site run only from a boat when seas are calm, and the draw is pelagic movement along the wall rather than an easy casual entry. Plan for drift control, a skipper who is reading the sea state well, and a dive that rewards patience more than quick laps around a shallow reef.
