Named after the East End lighthouse found directly onshore — at one of the highest points on the whole island — Lighthouse Wall is formed of jagged rocky points jutting into the blue with flowing sandy channels between them plunging into the abyss. These razor-narrow protrusions of rock are a haven for marine life. In deep water, Star Corals form horizontal plates that spread outward from the wall against the will of gravity, and divers can look around them for Longsnout Butterflyfish hanging near narrow ledges in search of invertebrates.

During the deep wall section of the dive, divers can find an old sunken rope encrusted in algae and sponge growth, still gently swaying back and forth as it pendulums above the void. The contrast between this ghostly detail and the dramatic topography all around makes Lighthouse Wall one of the more atmospheric dives on the East End. The landmark lighthouse onshore, visible as a reference point throughout the dive, is a satisfying navigational anchor for divers who like to know exactly where they are.
