Whitehouse Rock is a boat-dived seamount off Havelock, rising from deep water into a series of coral-covered slopes and pinnacles. The shallowest sections turn into a bright reef garden, while the deeper faces hold fan corals, schooling fish, and hunting action. It is the kind of Andaman site that rewards slow drifting, good buoyancy, and a plan that lets you work the different sides one at a time.
