Named after the condo development directly onshore and its position on the island's northern shore, Northern Lights features a gently sloping bottom of alternating sand channels and sponge-encrusted coral fingers leading to a drop-off at 55–60 feet. Divers make their way down this slope and back up again, watching for a curious free-swimming Green Moray Eel that frequents the area. Looking far below while along the drop-off, divers can make out the faint outline of a shelf at around 200 feet — a vertigo-inducing sense of scale.

The narrow channels and overhangs along the wall are packed with abundant sponge growth, with long and stringy Rope Sponges growing in such numbers they form a tangled, alien-like mess of shapes and colors — some glowing neon green. A dive light is highly recommended here; the deeper you go, the more color is absorbed by the water, and restoring that light reveals the true vividness of the sponges and algae coating the wall.
