Tarpon Alley

Tarpon Alley is a wall dive on Grand Cayman's North Wall, one of a cluster of signature sites — alongside Babylon and Eagle Ray Pass — along a sheer vertical drop that plunges thousands of feet along the edge of the North Sound. It is one of 234 permanently moored sites maintained by the Cayman Islands Department of Environment around Grand Cayman, anchoring being banned in Marine Parks.

The wall top sits at roughly 60–65 feet (18–20 m), where the reef edge gives way to a sheer vertical face dropping into deep blue. The site is a boat dive, accessed via mooring, and is reached on calmer days when wind permits North Wall trips.

Tarpon Alley is known for large marine life: eagle rays, tarpon, reef sharks, and turtles cruise the blue water off the wall. Visibility is frequently excellent, commonly exceeding 100 ft (30 m) in the island's clear water.
