About this site
Chain Wall is a stunning vertical drop-off plunging over 2,000 feet, teeming with marine life. The wall is covered in vibrant sponges, black coral, and gorgonians. Schools of horse-eye jacks, barracuda, and reef sharks patrol the blue. The top of the wall starts at 40 feet, making it accessible for divers of various experience levels. Strong currents can occur, attracting pelagics. The visibility is often excellent, exceeding 100 feet. The site is part of Lighthouse Reef, known for pristine conditions and healthy coral.
