Introduction to Coco Island: Coco Island is located about 4 kilometers off the coast of Maliso, a village at the southwest tip of Guam. It is a small island with a total length of about 1.4 kilometers and a width of only 250 meters. With the calm sea and white-sand beach of Coco Island Lagoon on the north side, and the wave-whispering rocks of the outer reef on the south side, it is a rare resort with contrasting landscapes in Guam and a paradise for ocean sportsmen.
