About Keyhole
Keyhole is an outer-reef drift site on Guam's Orote Peninsula, set between a broad upper reef plateau and a wall that drops away quickly offshore. Most recreational dives stay on the shelf, weaving past large boulders that break up the flow and hold reef fish, turtles, and passing pelagics. When conditions are manageable it works well as a guided drift for less experienced divers, while the same layout also gives experienced teams a convenient starting point for deeper wall profiles.
