Gab Gab 2 is a base-access reef dive on Guam with heavy fish life.
Gab Gab 2 is a base-access Apra Harbor reef on Guam with a longer approach to a fish-heavy coral zone. It is better treated as a planned dive than a casual swim, with the main route built around coral heads, sponges, and feeding zones where jacks, nurse sharks, turtles, butterflyfish, and octopus are common. Warm water and usually workable visibility make it a steady Guam dive when the harbor is calm.
